PDF to EPUB Converter

How to Convert PDF to EPUB Online

1. Upload Your PDF: Drag and drop a PDF, or click "+ Add Files" to select one from your device. Batch conversion is supported, and files stay on our servers only long enough to process.
2. Confirm the Output Format: EPUB is already selected. The default settings are tuned to produce a reflowable EPUB 3 file with the PDF's text content, headings, paragraphs, lists, and embedded images mapped into XHTML chapters.
3. (Optional) Add More PDFs to Batch: Queue several files in the same session — each one converts independently and downloads as its own .epub.
4. Convert and Download: Click "Convert", then download the .epub. Sideload it to a Kindle via Send to Kindle, drop it into Apple Books, Calibre, Kobo, Nook, or any EPUB-compatible reader.

Why Convert PDF to EPUB?

PDF was designed in 1993 to print and display a page exactly as authored — fixed page size, fixed line breaks, fixed font positioning. That works on paper and on desktop screens, but a 6" Kindle, a phone, or a smartwatch can't reflow PDF text without ugly pinch-zoom and horizontal scrolling. EPUB is an open IDPF/W3C standard built around reflowable XHTML inside a ZIP container, so the text adapts to whatever screen and font size the reader prefers.

• Reflowable text on small screens — Adjust font size, family, line height, and margins on a Kindle Paperwhite, Kobo Clara, or iPhone without re-rendering the PDF's fixed page geometry.
• Native e-reader format — Apple Books, Kobo, Nook, Google Play Books, Tolino, and PocketBook all use EPUB as their primary ingest format. PDFs technically open but are second-class citizens.
• Kindle now accepts EPUB — Amazon's Send to Kindle service began accepting .epub files in mid-2022 and retired MOBI uploads on December 20, 2023. EPUBs are converted server-side into Kindle's modern KF8/KFX format on delivery.
• Accessibility and night mode — Screen readers, text-to-speech, dyslexia-friendly fonts, and dark themes all work on EPUB because the underlying content is real XHTML, not a flattened page image.
• Smaller files for text-heavy books — A 400-page novel exported from Word as PDF is often 5-15 MB; the same content as EPUB is typically under 2 MB because there's no per-page font/layout overhead.
• Annotations sync across devices — Highlights and bookmarks made in Apple Books or Kobo sync to your account; PDF annotations are usually trapped on whichever app made them.

PDF vs EPUB — Reading Experience Compared

E-Reader and App Compatibility

Reflowable vs Fixed-Layout EPUB

Our converter produces a reflowable EPUB, which is the right choice for novels, reports, articles, manuals, and most text-heavy PDFs. Reflowable means text rewraps to fit the screen; line breaks, page breaks, and column layouts from the original PDF are not preserved verbatim — by design.

If your PDF is a magazine, comic, children's picture book, photo book, or form with pixel-precise positioning, a fixed-layout EPUB (or keeping the file as PDF) is usually a better fit. Fixed-layout EPUB hard-codes each page's geometry and is supported by Apple Books and Kobo but only partially on Kindle.

Works well: novels, non-fiction prose, technical manuals, single-column reports, articles, theses.

Works less well: magazines with multi-column spreads, scanned PDFs without OCR, forms, comics, layout-heavy designed PDFs. For scanned PDFs, run OCR first (in Acrobat, ABBYY FineReader, or Calibre's OCR plugin) so the EPUB contains real text rather than page images.

Frequently Asked Questions

Will my PDF's exact page layout be preserved?

No, and that's intentional. EPUB is a reflowable format — text rewraps to fit whatever screen, font size, and orientation the reader chooses. Headings, paragraphs, bold/italic styling, bulleted lists, and inline images carry over. Multi-column layouts collapse to a single column, page numbers and running headers are dropped, and pixel-precise positioning is replaced by CSS flow.

Can I send the EPUB to a Kindle?

Yes. Amazon's Send to Kindle (web, email, iOS/Android app, Mac/PC desktop app) has accepted EPUB uploads since mid-2022 and dropped MOBI support entirely on December 20, 2023. Email your .epub to your @kindle.com address or drop it into the Send to Kindle web app; Amazon converts it to KF8/KFX on its servers before delivering to your device. The file must be DRM-free.

What about scanned PDFs — will the text be searchable?

Only if the PDF already contains an OCR text layer. A scanned PDF is a sequence of page images; without OCR the converter has no real text to extract, and the resulting EPUB will either be empty or contain those images with no searchable text. Run OCR first (Acrobat Pro, ABBYY FineReader, or a free tool like Tesseract) and then convert the OCRed PDF here. Calibre's conversion docs explicitly note that PDFs without an embedded text layer cannot be converted to reflowable EPUBs.

Do images and chapter structure transfer?

Embedded images are extracted and re-referenced inside the EPUB's OEBPS folder. Chapter structure is derived from heading styles and bookmarks when present in the PDF — if the PDF has no heading marks or table of contents, the converter falls back to splitting on page breaks. For best chapter detection, export PDFs from Word, Pages, or LaTeX with real heading styles rather than oversized bold text.

How does this compare with Calibre for PDF-to-EPUB conversion?

Calibre is the most powerful open-source option and is excellent if you want to tune heuristics, edit metadata, and batch hundreds of files locally. It also has a steep learning curve and requires installing a 250+ MB desktop app. Our online converter is a faster choice when you have a handful of files, don't want to install anything, and are happy with reasonable defaults. Both produce reflowable EPUBs from the same source PDF; results on heavily designed PDFs will be imperfect either way.

Will fonts from the PDF carry over?

Generally no — and you usually don't want them to. EPUB readers prefer to honor the reader's chosen font (system serif, sans-serif, or a dyslexia-friendly face) so the file stays small and accessible. The converter preserves font weights and styles (bold, italic) via CSS, but the actual typeface is left to the e-reader unless you edit the EPUB later in Calibre or Sigil to embed a font.

Can I combine multiple PDFs into one EPUB?

Not directly in a single click — each PDF converts to its own EPUB. If you need one combined ebook, first use Merge PDF to join the PDFs into one file, then convert that merged PDF to EPUB here.

Is there a file size limit?

The free tool handles typical ebook-sized PDFs comfortably; very large scanned PDFs (hundreds of megabytes) may time out in-browser before they finish uploading. If you hit a limit, OCR and downsample the scan first, or split the PDF into smaller chunks before converting.

What's the difference between EPUB, MOBI, and AZW3?

EPUB is the open W3C standard used by Kobo, Apple Books, Nook, and modern Kindles. MOBI is Amazon's legacy Mobipocket-based format, retired for new Send to Kindle uploads on December 20, 2023. AZW3 (KF8) is Amazon's proprietary follow-up to MOBI, still used internally on Kindle devices but not as a sideloading format. For new conversions in 2026, EPUB is the right target — Kindle accepts it directly and every other major reader treats it as the native format. If you specifically need MOBI for an older Kindle, see PDF to MOBI.
