Convert PDF to EPUB Online Free

Stop pinch-zooming PDFs on your e-reader.

A PDF page is a fixed A4 sheet, so on a 6-inch screen it's tiny or cut off. An EPUB is just text and pictures that flow to fit any screen at any size. Resize the reader below and compare how each copes.

The whole A4 page is shrunk to fit. On a 6.8″ screen the body text is about 3 px: readable only by zooming and panning, line by line.

~/convert-and-count

Convert it, then count what came through.

Chapters, words, styling, cover and metadata are counted in your book, and again in the converted file after reading it back. DRM-protected books are detected and refused. Everything happens in this tab.

lockAbout DRM: books bought from stores like Kindle or Kobo are usually copy-protected. This page reads encryption.xml and the MOBI header and refuses encrypted books; font obfuscation (used by many DRM-free EPUBs to protect embedded fonts) is not DRM and is allowed.

~/what-kind-of-pdf

A novel converts beautifully. A textbook fights back.

The more a PDF relies on exact page layout, the less it gains from flowing. Pick the kind of document to see what the EPUB will be like, and whether it's worth converting at all.

Things that belong to paper, removed before they reach your reader.

A PDF is full of print leftovers that make no sense once text flows. Without cleanup, an EPUB has "Page 47" and the book's title every few paragraphs. Switch each fix off to see what it prevents.

Frequently Asked Questions

Is converting PDF to EPUB free?

Yes, PDF to EPUB conversion is completely free with no signup, no watermark, and no usage limit. Convert as many files as you need.

Are my files uploaded to a server?

Your PDF to EPUB file is sent over an encrypted connection to our servers, converted, and returned to you. Files are processed only to perform the conversion and are not stored or retained afterward, so they are removed automatically once your download is ready.

How long does PDF to EPUB conversion take?

Most PDF to EPUB conversions finish in under a minute. A large file takes longer in proportion, though the work happens on your machine, so nothing waits on a sign-up.

Will the conversion reduce file quality?

Depends which formats. Lossless in, lossless out, and the file you get back is identical. Convert to something compressed and you trade a little quality for a smaller file, which is usually the trade you wanted.

Does this work on mobile devices?

Yes. The PDF to EPUB converter works on phones, tablets, and desktops in any modern browser including Chrome, Safari, Firefox, and Edge.
