PDF to EPUB

Amazon, Apple Books, Kobo, and Google Play Books all accept EPUB. None of them accept PDF as a publishable ebook format. So if you wrote your book in Word, exported it to PDF, and now want to distribute it across multiple ebook platforms, the PDF is a dead end. EPUB is the ISO-standardized open format that every major ebook platform and reading app understands natively. Converting your PDF to EPUB is the step between having a finished document and having an actual ebook that readers can buy, download, and read on any device they own. This browser-based converter handles it locally with custom title and language metadata embedded, and nothing uploaded to any server.

How It Works

1. Upload your PDF: Click or drag the file into the drop zone. Files up to 50MB are accepted. PDF.js loads the document directly in your browser. No data leaves your device at any point in the process.
2. Configure your ebook metadata: Enter a custom title for the ebook so it displays correctly in any reader's library, select the document language (English, Urdu, Spanish, or French) for proper text rendering and metadata tagging, and set a custom page range if you only need specific sections converted rather than the full document.
3. Convert and download: The tool extracts text from each PDF page using PDF.js, structures it as reflowable XHTML content, writes the required content.opf package file and toc.ncx navigation document, packages everything according to the EPUB 2 specification into a ZIP-based .epub archive, and delivers it for immediate download. The output opens natively in Apple Books, Kobo, Google Play Books, and Kindle via Send to Kindle.

Compatibility and Support

Supported Input and Output Formats

• Input: Standard digital (text-selectable) PDF files up to 50MB, single-page and multi-page
• Output: EPUB ebook file compatible with Kindle (via Send to Kindle), Apple Books, Kobo, Google Play Books, and any EPUB-reading app including Adobe Digital Editions and Calibre
• Metadata: Custom ebook title and language embedded in the EPUB package file
• Page range: All pages or a custom range

Unsupported Formats

• Scanned PDFs (image-only pages): There is no extractable text in scanned documents. The resulting EPUB will be empty. Run OCR on the PDF first to add a text layer before converting. Test quickly by trying to select text in the PDF with your cursor before uploading.
• Password-protected PDFs: Encryption blocks PDF.js from accessing the content. Remove the password before conversion.
• Non-PDF inputs: Other formats need to be in PDF form first. For a Word manuscript going directly to EPUB, convert it to PDF via the Word to PDF converter, then convert to EPUB.

File Size Limits

The tool supports PDFs up to 50MB. Since all processing runs in your browser, image-heavy PDFs near the limit may take a few seconds longer on low-RAM devices. For large documents, converting in sections using the custom page range and combining chapters afterward in Calibre is a practical workaround.

Who Should Use This Tool?

• Students: A graduate student who has their dissertation or thesis in PDF and wants to add it to their Kobo or Apple Books library for comfortable reading during a long commute. EPUB text reflows to the screen width and allows font size adjustment; the same document as a PDF requires constant zooming and horizontal scrolling on a 6-inch e-ink screen.
• Freelancers: An indie author who finished their novel, has the final manuscript as a formatted PDF, and wants to upload it to Draft2Digital or Apple Books for distribution. EPUB is the required upload format for both platforms and most ebook retailers.
• Office Professionals: A corporate trainer who wrote a comprehensive training manual in PDF and needs to distribute it as an ebook employees can read on their personal devices through Google Play Books or Apple Books without needing to print it.
• Developers: A developer building a content distribution platform who needs to convert user-uploaded PDFs to EPUB for delivery to a reading app. Browser-side conversion means no server infrastructure for file processing and no third-party handling of user content.

Why This Tool Beats the Alternatives

• No account creation or email required to access any feature
• No watermarks or promotional text inserted into the EPUB output
• No server upload; competing tools send manuscript content to remote servers even on their free tiers
• Custom metadata fields for title and language, not just a raw format conversion with no ebook identity
• Immediate browser-side processing with no queue or server wait time
• Page range selection for chapter-level conversion, not forced full-document output every time

Pro Tips

• Before uploading your manuscript PDF, check that it has selectable text. Open it and try to highlight a sentence. If you cannot select individual words, the PDF is image-based and will produce an empty EPUB. A quick OCR pass fixes this. If you can select text, the conversion will extract it cleanly.
• For self-publishing distribution, open the converted EPUB in Calibre (free desktop software) before uploading to any platform. Calibre's EPUB viewer shows exactly how the file will render on different screen sizes and lets you edit the metadata, add a cover image, and validate the file structure before submitting to Apple Books, Kobo, or Google Play Books.
• If you are converting a book with chapters, use the custom page range setting to convert each chapter separately and then combine the resulting EPUB files in Calibre using its merge function. Chapter-by-chapter conversion gives cleaner paragraph breaks and avoids the page-header and footer text from the PDF appearing as body content between sections.

Upload your PDF, enter your ebook title, pick a language, and download a distribution-ready EPUB in seconds. If you need to edit the source document before converting, the PDF to Word converter gets you an editable version first, and the PDF compressor can reduce file size if your source PDF is approaching the 50MB limit.
