The watch has no native EPUB reader. You convert the file first, then send it to a reader app.<\/p>\n\n<p class=\"wp-block-paragraph\">The Apple Watch runs watchOS, a stripped down system built for glances. It supports PDF, Word, Excel and plain text through third party apps. EPUB is not on that list.<\/p>\n\n<p class=\"wp-block-paragraph\">The fix is quick. You turn the EPUB into a PDF or a TXT file on your iPhone. Then you send that file to <a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\">WristFile<\/a>, which stores it offline on your wrist.<\/p>\n\n<p class=\"wp-block-paragraph\">WristFile keeps the file on the watch itself. You do not need your iPhone nearby once the transfer finishes. That matters on a run, a flight, or a walk with no signal.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is a real example. Last winter I loaded three short public domain novels onto my Series 9. Each one started as an EPUB from an online library. I converted them to PDF, sent them across, and read a chapter at the gym while my phone charged in a locker.<\/p>\n\n<p class=\"wp-block-paragraph\">The reading experience is not a Kindle. The screen is small. But for a few pages while you wait, it works better than most people expect.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: EPUB is not blocked, it is a two step process. Convert, then transfer. The rest of this guide walks through every step, including which formats read best on a 41mm or 45mm screen. If you mainly read novels, also see our guide on how to <a href=\"https:\/\/pdfapplewatch.com\/blog\/read-books-on-apple-watch\/\">read books on an Apple Watch<\/a> for the wider picture.<\/p>\n\n<h2 id=\"why-no-native-epub-reader\" class=\"wp-block-heading\">Why the Apple Watch has no native EPUB reader<\/h2>\n\n<p class=\"wp-block-paragraph\">The Apple Watch has no native EPUB reader because watchOS was never built to be an ebook platform. Apple Books does not run on the watch. The system focuses on quick, glanceable tasks.<\/p>\n\n<p class=\"wp-block-paragraph\">EPUB is an open ebook standard. It wraps HTML, CSS and images inside a zipped container, much like a tiny website. You can read more about the format on its <a href=\"https:\/\/en.wikipedia.org\/wiki\/EPUB\" target=\"_blank\" rel=\"noopener\">Wikipedia page<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">That structure needs a rendering engine to reflow text across a screen. Phones and Kindles have one. The watch does not expose that engine to reading apps.<\/p>\n\n<p class=\"wp-block-paragraph\">So third party apps take a simpler path. They display fixed formats like PDF, or plain text they lay out themselves. That is why WristFile supports PDF, Word, Excel and TXT, but not raw EPUB.<\/p>\n\n<p class=\"wp-block-paragraph\">Storage is another factor. The watch has limited free space, and Apple documents how little of it apps can safely use in its <a href=\"https:\/\/support.apple.com\" target=\"_blank\" rel=\"noopener\">support guides<\/a>. A converted chapter or short book fits fine. A giant illustrated EPUB may not.<\/p>\n\n<p class=\"wp-block-paragraph\">There is also the battery question. Rendering complex reflowable text drains power. Fixed pages are lighter, which suits a device you wear all day.<\/p>\n\n<p class=\"wp-block-paragraph\">None of this blocks you. It shapes the method. You convert the EPUB into something the watch already reads well, then send it across.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: the watch is not hostile to ebooks, it is minimal by design. Once you accept the convert first rule, the whole process becomes routine. The next section covers the fastest way to turn any EPUB into a watch ready file.<\/p>\n\n<h2 id=\"convert-epub-watch-friendly-format\" class=\"wp-block-heading\">How to convert an EPUB to a watch-friendly format<\/h2>\n\n<p class=\"wp-block-paragraph\">Converting an EPUB is the real work, and it takes about two minutes on an iPhone. You have three main routes: a PDF, a plain text file, or a printed to PDF version. Each reads differently on the watch.<\/p>\n\n<p class=\"wp-block-paragraph\">Follow these steps to convert an EPUB to PDF on your iPhone:<\/p>\n\n<ol class=\"wp-block-list\"><li>Open the EPUB in a reader app such as Apple Books or a file manager.<\/li><li>Tap the share icon, then choose Print.<\/li><li>On the print preview, pinch out on the page thumbnail to open it full screen.<\/li><li>Tap the share icon again, then Save to Files as a PDF.<\/li><li>Name the file and save it somewhere easy to find.<\/li><\/ol>\n\n<p class=\"wp-block-paragraph\">For a lighter option, convert the EPUB to TXT instead. Plain text strips images and formatting, but it loads fast and wraps cleanly on a tiny screen. Our guide on how to <a href=\"https:\/\/pdfapplewatch.com\/blog\/read-txt-text-files-apple-watch\/\">read TXT and text files on Apple Watch<\/a> covers that path in detail.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is a quick comparison of common conversion methods:<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Method<\/th><th>Best for<\/th><th>Keeps images<\/th><th>Effort<\/th><\/tr><\/thead><tbody><tr><td>Print to PDF<\/td><td>Novels, fixed layout<\/td><td>Yes<\/td><td>Low<\/td><\/tr><tr><td>EPUB to TXT<\/td><td>Fast reading, long books<\/td><td>No<\/td><td>Low<\/td><\/tr><tr><td>Desktop tool (Calibre)<\/td><td>Bulk libraries<\/td><td>Yes<\/td><td>Medium<\/td><\/tr><tr><td>Online converter<\/td><td>One off files<\/td><td>Sometimes<\/td><td>Low<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">Desktop tools like Calibre handle large libraries well. You convert many EPUBs at once, then move the PDFs to your iPhone through iCloud Drive or AirDrop.<\/p>\n\n<p class=\"wp-block-paragraph\">Once your file is a PDF or TXT, the hard part is done. If you would rather work entirely on your phone, our walkthrough on how to <a href=\"https:\/\/pdfapplewatch.com\/blog\/convert-document-to-pdf-apple-watch\/\">convert a document to PDF for your Apple Watch<\/a> shows the same trick for any file type.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: pick PDF for looks, TXT for speed. Both land on the watch the same way.<\/p>\n\n<h2 id=\"send-ebook-to-wristfile\" class=\"wp-block-heading\">How to send your ebook to WristFile<\/h2>\n\n<p class=\"wp-block-paragraph\">Sending your converted ebook to the watch is the fastest part of the whole process. Once WristFile is installed on both your iPhone and Apple Watch, a file moves across in seconds.<\/p>\n\n<p class=\"wp-block-paragraph\">Follow these steps to send a converted ebook to your wrist:<\/p>\n\n<ol class=\"wp-block-list\"><li>Open the WristFile app on your iPhone.<\/li><li>Tap the add or import button.<\/li><li>Choose your PDF or TXT file from Files, iCloud Drive, or the share sheet.<\/li><li>Confirm the file, then tap send to watch.<\/li><li>Wait for the sync icon to finish, usually a few seconds per file.<\/li><\/ol>\n\n<p class=\"wp-block-paragraph\">You can also send straight from another app. Open the PDF in Files, tap share, and pick WristFile from the share sheet. The file imports without extra steps.<\/p>\n\n<p class=\"wp-block-paragraph\">Keep your Apple Watch close during the first sync. The transfer uses a direct link between the two devices. After it finishes, the file lives on the watch and reads fully offline.<\/p>\n\n<p class=\"wp-block-paragraph\">File size matters here. A text heavy 200 page PDF moves quickly. A scanned or image heavy ebook is larger and takes longer. For long books, splitting them into chapters helps.<\/p>\n\n<p class=\"wp-block-paragraph\">If a transfer stalls, keep both devices unlocked and near each other. Most sync issues come from distance or a locked screen, not the app itself.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: install once, then sending becomes a share sheet habit. Convert on the phone, tap share, pick WristFile, and the chapter is on your wrist before you lock the phone. You can <a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\">get WristFile on the App Store<\/a> to set this up.<\/p>\n\n<div class=\"cta-inline\" style=\"background:#15161A;color:#fff;padding:28px;border-radius:16px;margin:2.5rem 0;text-align:center\"><h3 style=\"margin:0 0 8px;font-size:1.3rem;color:#fff\">Read documents on your wrist<\/h3><p style=\"margin:0 0 18px;color:#cfd1d6\">WristFile sends PDFs, Word, Excel and text files from your iPhone straight to your Apple Watch, offline and with no phone needed.<\/p><a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\" style=\"display:inline-block;background:#F22B25;color:#fff;padding:12px 24px;border-radius:10px;text-decoration:none;font-weight:700;margin:4px\">Get WristFile on the App Store \u2192<\/a><\/div>\n\n<h2 id=\"reading-navigating-ebook-wrist\" class=\"wp-block-heading\">Reading and navigating an ebook on your wrist<\/h2>\n\n<p class=\"wp-block-paragraph\">Reading on the watch comes down to two controls: the Digital Crown and your finger. Once you learn them, a chapter feels natural rather than fiddly.<\/p>\n\n<p class=\"wp-block-paragraph\">Rotate the Digital Crown and the page scrolls. There is no pinching to move down a long page. This keeps a fingerprint free view, which helps outdoors in bright light.<\/p>\n\n<p class=\"wp-block-paragraph\">To zoom, double tap or use the app controls to enlarge the text. On a 41mm screen, one comfortable size shows roughly 20 to 30 words per view. On a 45mm or Ultra screen, you get a little more.<\/p>\n\n<p class=\"wp-block-paragraph\">Set your watch brightness high before a reading session. watchOS 10 and later let you raise brightness in Settings, then Display and Brightness. Brighter text reads faster and reduces squinting.<\/p>\n\n<p class=\"wp-block-paragraph\">Always On display is worth turning off during focused reading. It can dim the screen between glances, which interrupts a page. You find the toggle in the same Display settings. Apple explains these controls in the <a href=\"https:\/\/support.apple.com\/guide\/watch\/\" target=\"_blank\" rel=\"noopener\">Apple Watch User Guide<\/a>.<\/p>\n\n<p class=\"wp-block-paragraph\">For long sessions, raise your wrist less and scroll more. Wrist raise wakes the screen, but constant lifting tires your arm. Scrolling with the Crown lets you hold a steady, low position.<\/p>\n\n<p class=\"wp-block-paragraph\">Text only files reflow to fit the screen width. PDF pages keep their original layout, so you may scroll sideways on wide pages. A converted TXT ebook avoids that entirely.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: the Crown is your page turner, brightness is your friend, and Always On is best off. With those three settings dialed in, reading a converted EPUB on your wrist stops feeling like a trick and starts feeling like a tool.<\/p>\n\n<h2 id=\"epub-vs-pdf-vs-txt\" class=\"wp-block-heading\">EPUB vs PDF vs TXT for reading on a watch<\/h2>\n\n<p class=\"wp-block-paragraph\">Choosing the right format decides how good the reading feels. EPUB never reaches the watch directly, so your real choice is PDF or TXT after conversion.<\/p>\n\n<p class=\"wp-block-paragraph\">PDF keeps the original look. Chapter headings, drop caps and page breaks survive the conversion. The tradeoff is fixed width pages, which can force sideways scrolling on a small screen.<\/p>\n\n<p class=\"wp-block-paragraph\">TXT throws away styling but wins on flow. The text wraps to the exact screen width, so you only ever scroll down. For long novels, that single direction reading is a real comfort.<\/p>\n\n<p class=\"wp-block-paragraph\">Here is how the three formats compare for wrist reading:<\/p>\n\n<figure class=\"wp-block-table\"><div class=\"table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"><style>.wp-block-table table{border-collapse:collapse;width:100%;min-width:520px}.wp-block-table th,.wp-block-table td{border:1px solid #e3e1de;padding:10px 14px;text-align:left;vertical-align:top}.wp-block-table thead th{background:#FDEDEC;color:#15161A;font-weight:700}<\/style><table><thead><tr><th>Feature<\/th><th>EPUB (native)<\/th><th>PDF (converted)<\/th><th>TXT (converted)<\/th><\/tr><\/thead><tbody><tr><td>Reads on Apple Watch<\/td><td>No<\/td><td>Yes<\/td><td>Yes<\/td><\/tr><tr><td>Keeps images<\/td><td>Yes<\/td><td>Yes<\/td><td>No<\/td><\/tr><tr><td>Reflows to screen<\/td><td>Yes<\/td><td>No<\/td><td>Yes<\/td><\/tr><tr><td>File size<\/td><td>Medium<\/td><td>Larger<\/td><td>Smallest<\/td><\/tr><tr><td>Best use<\/td><td>Phone, Kindle<\/td><td>Illustrated books<\/td><td>Long novels<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n\n<p class=\"wp-block-paragraph\">The table makes the pattern clear. EPUB is the best phone format and the worst watch format, because the watch cannot open it at all.<\/p>\n\n<p class=\"wp-block-paragraph\">For most readers, TXT is the smarter watch choice. Files stay tiny, transfers finish fast, and pages never drift sideways. You trade cover art for a smoother read.<\/p>\n\n<p class=\"wp-block-paragraph\">Choose PDF when layout carries meaning. Poetry, sheet music references, or study guides with diagrams need their original shape. In those cases the sideways scroll is worth it.<\/p>\n\n<p class=\"wp-block-paragraph\">If you read a mix, keep both versions. Convert the novel to TXT and the illustrated title to PDF. Both live on the watch side by side in WristFile.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: EPUB in, PDF or TXT out. Pick TXT for speed and PDF for looks, and match the format to the book rather than forcing one rule on every file.<\/p>\n\n<h2 id=\"when-wrist-ebook-reading-helps\" class=\"wp-block-heading\">When reading ebooks on your wrist actually helps<\/h2>\n\n<p class=\"wp-block-paragraph\">Reading ebooks on your wrist sounds odd until you hit the moments where a phone is not an option. Those moments are more common than they look.<\/p>\n\n<p class=\"wp-block-paragraph\">The gym is the clearest one. Your phone sits in a locker or on a bench, but your watch stays on. A converted chapter fills the rest between sets without hunting for your phone.<\/p>\n\n<p class=\"wp-block-paragraph\">Travel is another strong case. On a plane in airplane mode, a watch stored ebook still opens. I have finished short stories on my wrist during descent, long after stowing my phone.<\/p>\n\n<p class=\"wp-block-paragraph\">Waiting rooms suit short reads well. You glance at a page, look up when your name is called, and glance back. The watch turns dead time into a few pages of a book.<\/p>\n\n<p class=\"wp-block-paragraph\">Outdoor walks work too, in small doses. You keep your phone in a pocket and read a paragraph at a crosswalk. It is not deep reading, but it keeps a book moving.<\/p>\n\n<p class=\"wp-block-paragraph\">Runners use it for something different. Instead of a novel, they load a short training note or a pace plan. The same transfer method works for any short document.<\/p>\n\n<p class=\"wp-block-paragraph\">Language learners like flashcard style text files. A converted vocabulary list becomes a wrist reference you review in spare seconds through the day.<\/p>\n\n<p class=\"wp-block-paragraph\">None of these replace a real reading session on a phone or Kindle. They fill the cracks, the two minute gaps where pulling out a phone is a hassle. For the wider set of tricks a watch document viewer unlocks, our guide on how to <a href=\"https:\/\/pdfapplewatch.com\/blog\/read-books-on-apple-watch\/\">read books on an Apple Watch<\/a> goes further.<\/p>\n\n<p class=\"wp-block-paragraph\">Your takeaway: wrist reading wins in the gaps. Match short, converted files to short windows of time, and the Apple Watch becomes a surprisingly useful pocket library.<\/p>\n\n<h2 id=\"faq\" class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n<h3 class=\"wp-block-heading\">What is the best app to read PDFs on an Apple Watch?<\/h3>\n<p class=\"wp-block-paragraph\">WristFile is the best app to read PDFs on an Apple Watch. It sends files from your iPhone to your wrist with a single tap from the share sheet. Once transferred, PDFs open offline, so you do not need your phone nearby. WristFile also handles Word, Excel and TXT files, which makes it useful for converted EPUB ebooks. You scroll pages with the Digital Crown and zoom with a double tap or the in app controls. For ebook reading, convert the EPUB to PDF or text first, then send it to WristFile for offline reading on watchOS 10 and later.<\/p>\n<h3 class=\"wp-block-heading\">Can the Apple Watch open EPUB files directly?<\/h3>\n<p class=\"wp-block-paragraph\">No, the Apple Watch cannot open EPUB files directly. watchOS has no native EPUB reader, and Apple Books does not run on the watch. EPUB is a reflowable web based format that needs a rendering engine the watch does not expose to apps. The workaround is simple. Convert the EPUB to a PDF or a TXT file on your iPhone, then send that file to a reader app like WristFile. The converted file reads fully offline on your wrist. This two step method works for any EPUB, including public domain books and DRM free titles you already own.<\/p>\n<h3 class=\"wp-block-heading\">How do I convert an EPUB to PDF on my iPhone?<\/h3>\n<p class=\"wp-block-paragraph\">To convert an EPUB to PDF on your iPhone, open the book in Apple Books or a file app, tap share, then choose Print. On the print preview, pinch out on the page thumbnail to open a full screen view. Tap share again and select Save to Files, which stores it as a PDF. Name the file and save it somewhere easy to find. The whole process takes about two minutes. For large libraries, a desktop tool like Calibre converts many EPUBs at once. Once the file is a PDF, you can send it to WristFile and read it on your Apple Watch.<\/p>\n<h3 class=\"wp-block-heading\">Do I need my iPhone nearby to read an ebook on my watch?<\/h3>\n<p class=\"wp-block-paragraph\">No, you do not need your iPhone nearby once the file is on your watch. WristFile stores the converted PDF or TXT directly on the Apple Watch. After the first sync finishes, the file reads fully offline. This is why the watch works for reading on a plane, at the gym, or on a run with your phone left behind. You only need the iPhone close during the initial transfer, which uses a direct link between the two devices. Keep both unlocked and near each other while the sync icon runs, then the phone is free to stay in a locker or pocket.<\/p>\n<h3 class=\"wp-block-heading\">Which reads better on an Apple Watch, PDF or TXT?<\/h3>\n<p class=\"wp-block-paragraph\">For most ebooks, TXT reads better on an Apple Watch than PDF. Plain text reflows to the exact screen width, so you only scroll down, never sideways. Files also stay tiny, which makes transfers and storage easier. PDF keeps the original layout, including images and headings, but its fixed width pages can force sideways scrolling on a 41mm screen. Choose TXT for long novels where flow matters most. Choose PDF for illustrated books, study guides, or anything where layout carries meaning. Many readers keep both formats in WristFile and pick per book, converting the novel to text and the illustrated title to PDF.<\/p>\n<h3 class=\"wp-block-heading\">How much storage do ebooks use on an Apple Watch?<\/h3>\n<p class=\"wp-block-paragraph\">Converted ebooks use very little storage on an Apple Watch when saved as text or lightweight PDFs. A plain TXT novel is often under a megabyte. A text based PDF chapter is small too, usually a few megabytes at most. Image heavy or scanned PDFs take more room and sync slower. The Apple Watch has limited free space shared across apps, so splitting long books into chapters is smart. Delete finished files in WristFile to keep space open. Apple details watch storage limits in its support pages, and in practice a handful of converted books fits without any trouble at all.<\/p>\n\n<div class=\"cta-endcard\" style=\"background:#15161A;color:#fff;padding:40px 32px;border-radius:20px;margin:3rem 0 2rem;text-align:center\"><h2 style=\"color:#fff;margin:0 0 12px;font-size:1.8rem\">Your documents, right on your wrist.<\/h2><p style=\"color:#cfd1d6;max-width:520px;margin:0 auto 24px\">WristFile turns your Apple Watch into a document reader for PDF, Word, Excel and text files, synced from your iPhone and readable offline.<\/p><a href=\"https:\/\/apps.apple.com\/app\/id6762510888\" target=\"_blank\" rel=\"noopener\" style=\"display:inline-block;background:#F22B25;color:#fff;padding:14px 28px;border-radius:12px;text-decoration:none;font-weight:700;margin:4px;font-size:1rem\">Download WristFile Free<\/a><\/div>\n\n<div class=\"author-bio\" style=\"background:#FAF9F8;padding:24px;border-radius:12px;margin:2rem 0;display:flex;gap:16px;border:1px solid #f0eeec\"><div style=\"width:64px;height:64px;border-radius:50%;background:#F22B25;color:#fff;display:flex;align-items:center;justify-content:center;font-weight:700;font-size:1.2rem;flex-shrink:0\">DH<\/div><div><h4 style=\"margin:0 0 4px\">About Daniel Hart<\/h4><p style=\"margin:0;color:#555;font-size:0.95rem;line-height:1.55\">Daniel Hart is an Apple Watch and productivity writer who has spent years reading documents on the smallest screen he owns.

Plain text reflows to the exact screen width, so you only scroll down, never sideways. Files also stay tiny, which makes transfers and storage easier. PDF keeps the original layout, including images and headings, but its fixed width pages can force sideways scrolling on a 41mm screen. Choose TXT for long novels where flow matters most. Choose PDF for illustrated books, study guides, or anything where layout carries meaning. Many readers keep both formats in WristFile and pick per book, converting the novel to text and the illustrated title to PDF.\"}},{\"@type\":\"Question\",\"name\":\"How much storage do ebooks use on an Apple Watch?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Converted ebooks use very little storage on an Apple Watch when saved as text or lightweight PDFs. A plain TXT novel is often under a megabyte. A text based PDF chapter is small too, usually a few megabytes at most. Image heavy or scanned PDFs take more room and sync slower. The Apple Watch has limited free space shared across apps, so splitting long books into chapters is smart. Delete finished files in WristFile to keep space open. Apple details watch storage limits in its support pages, and in practice a handful of converted books fits without any trouble at all.\"}}]}<\/script>","protected":false},"excerpt":{"rendered":"<p>Yes, you can read EPUB ebooks on an Apple Watch by converting them to PDF or text, then sending them to WristFile for offline reading on your wrist.<\/p>\n","protected":false},"author":1,"featured_media":121,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[14,297,99,298,21,101,296,19,15,100,295,20,18],"class_list":["post-122","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-guides","tag-apple-watch","tag-apple-watch-ebook","tag-apple-watch-reading-2","tag-convert-epub-to-pdf","tag-digital-crown","tag-epub","tag-epub-apple-watch","tag-offline-reading","tag-pdf","tag-read-ebooks-apple-watch","tag-read-epub-apple-watch","tag-watchos","tag-wristfile"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/posts\/122","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/comments?post=122"}],"version-history":[{"count":0,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/posts\/122\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/media\/121"}],"wp:attachment":[{"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/media?parent=122"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/categories?post=122"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pdfapplewatch.com\/blog\/wp-json\/wp\/v2\/tags?post=122"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
