EPUB to PDF Converter

About the EPUB to PDF Converter

Turn an e-book without DRM into a PDF: EPUB (2 and 3), Kindle MOBI and AZW3, FB2 and CBZ comics. The whole book is laid out on the page size you choose — A5 for a book-like PDF, A4 or Letter for printing at home — with your margins and text size, a cover page and a contents page whose entries link to the chapters. Every chapter starts on a new page, and pictures and fixed-layout pages are fitted to the page.

With a pass, the PDF is made by your browser’s own print engine (Save as PDF), so the text stays real, selectable and searchable text in every script your device can show. The book is read on your device and never uploaded, and anything in it that could run — scripts, event handlers, embedded frames — is removed before it is laid out.

Common uses

• Printing an e-book, or part of one, on paper at home or at a print shop.
• Reading a book on a device or app that opens PDFs but not EPUB.
• Sharing a book you wrote as a PDF proof that looks the same everywhere.
• Keeping a PDF copy of a book without DRM, with its pictures and contents.

How the book is laid out

The documents of the book are taken in its reading order (from the EPUB package’s spine — see W3C EPUB 3.3), followed by documents outside the reading order such as notes. Each starts on a new page and keeps its own stylesheet, which is limited to that document so one chapter’s styles can’t change another’s. Links inside the book — footnotes, cross-references, the contents page — point to the right place in the PDF.

A document that is only a picture (a cover, a full-page illustration, a comic page) becomes one page with the picture as big as fits. Fixed-layout pages (picture books, some cookbooks and comics) keep their layout and are scaled down to fit one sheet each. When you add a cover page, the book’s own cover page is left out so it doesn’t appear twice; a book without a cover picture gets a title page with its title and author instead.

Page size, margins and text size

The preview is exactly as wide as the printable area of the page (page width minus margins, at 96 CSS pixels per inch), so it wraps lines as the PDF will. Text size scales the book’s text from 70 % to 200 %; books that set their sizes in pixels or points change less. Where pages break inside a chapter is decided by your browser, which avoids breaking right after headings and inside pictures. Page numbers are printed in the bottom margin by Chrome and Edge (version 131 and later); in other browsers, turn on the print dialog’s own page numbers or headers and footers if you want them.

What happens to your book

Nothing is uploaded: the book is unpacked and laid out in this page on your device. Each document is cleaned before it is shown — scripts, event-handler attributes, frames, objects and javascript: links are removed — and laid out in a frame that isn’t allowed to run scripts. Pictures, stylesheets and fonts come only from the book’s own files; nothing is fetched from the web. Archives are checked before they are unpacked: books that would unpack to more than 2 GB, or with files that expand suspiciously far (zip bombs), are refused.

Limitations

• DRM-protected books (Adobe, Readium LCP, Apple Books, Kindle Store) can’t be converted, and neither can KFX files.
• Very long or heavily illustrated books take a while to prepare and need plenty of memory: up to 60 MB of text and markup and 5,000 documents are laid out at once.
• Audio, video and interactive content don’t carry over; scripts in a book never run.
• Fixed-layout two-page spreads are printed as single pages.
• Whether page numbers, background colours and links make it into the PDF depends on your browser’s print engine; Chrome and Edge keep all three.
• The cleaner that makes books safe to show loads on first use, so the first conversion needs an internet connection.
