Convertir un PDF en ebook ePub
This tool converts any PDF file into EPUB format, the open e-book standard supported by virtually every e-reader, including Kobo, Apple Books, and Adobe Digital Editions. The conversion extracts text and structure from your PDF and reformats it into a reflowable document that adapts to any screen size or font setting.
Your files never leave your device. The entire conversion runs locally in your browser using WebAssembly, no server upload, no account required, no file size logged anywhere. Close the tab and nothing persists.
PDF to EPUB conversion is useful when you want to read a document comfortably on an e-reader or mobile app: a research paper that's painful to scroll on a Kindle, a novel or report shared as a PDF that you want to reflow to your preferred font size, or an older e-book distributed in PDF format that you need in a format your reading app actually supports. It also works well for educators packaging course materials into a format students can annotate on their devices.
EPUB is a reflowable format, which means it intentionally drops fixed page layouts in favor of text that adapts to the reader's screen and settings. Simple formatting like headings, paragraphs, bold, and italics is preserved. Complex multi-column layouts, figures with precise placement, or heavily designed PDFs will reflow and may look different, this is expected behavior for any PDF-to-EPUB tool, not a limitation specific to this converter.
Scanned PDFs contain images of text rather than actual text data. Without OCR (optical character recognition), a scanned PDF will convert to an EPUB with embedded images rather than readable text. For best results, use a PDF that was created digitally (exported from Word, LaTeX, InDesign, etc.). If you only have a scanned file, run it through an OCR tool first to generate a text-based PDF, then convert that to EPUB.
EPUB is supported by Kobo, Apple Books, PocketBook, Tolino, Onyx Boox, and most Android reading apps including Moon+ Reader, ReadEra, and Lithium. Amazon Kindle does not natively support EPUB on older hardware, but Kindle devices running firmware 5.16.2.1 or later (released 2022) support EPUB directly. If you have an older Kindle, you would need to convert the EPUB to MOBI or AZW3 as a second step.
Because processing happens entirely in your browser, the practical limit depends on your device's available memory rather than a server-side cap. Most PDFs under 50 MB convert without issue on a standard laptop or desktop. Very large PDFs (hundreds of pages with embedded images) may be slow on older devices or mobile browsers. There is no artificial limit imposed by the tool itself.
Some PDFs embed text as vector paths or use non-standard font encoding, which makes the underlying text inaccessible to extraction tools. This is common with PDFs exported from certain design software or protected with editing restrictions. If your output EPUB is missing content, check that the original PDF allows text selection (try selecting text in a PDF viewer first). If it doesn't, the PDF may need to be processed with OCR before conversion produces usable output.
