Convert EPUB to PDF

Lay a reflowable ebook out on fixed pages — your paper size, your margins, your type size — and save it as a PDF you can print or annotate.

Everything happens on your own machine. The file is never sent anywhere.

EPUB and PDF answer opposite questions. An EPUB carries text that reflows to fit whatever screen it lands on, which is why the same book looks right on a phone and on a 13-inch reader. A PDF fixes every line in place on a page of a stated size, which is why it prints predictably and why annotation tools can point at a spot and expect it to stay there.

So converting EPUB to PDF is not a translation between two ways of storing the same thing. It is a decision: somebody has to choose the paper size, the type size and the margins, because the ebook never had them. On this page that somebody is you, and the three controls above are the whole decision.

The layout is done by your own browser's print engine rather than a JavaScript PDF library. That is a deliberate choice. Your browser is a real typesetter with justified text, hyphenation, orphan and widow control, and — the part that matters most — access to every font installed on your machine. A JavaScript writer has to embed a font file for every script it supports, which either bloats the download or silently drops characters. Vietnamese, Chinese, Japanese, Korean, Greek, Cyrillic and Arabic all come out right this way.

EPUB and PDF, side by side

What it does EPUB PDF
Layout Reflows to any screen Fixed pages at a stated size
Type size The reader chooses You choose, once, at conversion
Best for Reading on a phone, tablet or e-ink reader Printing, annotating, archiving, submitting
Page numbers None — there are no pages Real and stable
File size Smaller; text and images only Larger; fonts are embedded too
Editing later Structure is easy to re-flow Hard — the layout is baked in

What actually changes

Someone has to decide where the pages break

An EPUB has no pages; it has text that flows. Making a PDF means choosing a paper size and a type size, and those choices are yours. The result will not look like the publisher's own PDF edition, because that was designed page by page and this is laid out from the ebook's markup.

What survives

  • Headings, emphasis, lists and block quotes
  • Justified text with real hyphenation
  • Every font your system has, including Vietnamese and CJK
  • Chapter breaks on new pages
  • Images that live inside the EPUB

What does not

  • The publisher's own stylesheet and page design
  • Reflowability — a PDF is fixed forever
  • Interactive links to elsewhere in the book
  • The EPUB's own table of contents as a clickable index

How it works

Three steps, no waiting room

Drop the EPUB in

Read on your machine, as always. Its title, author and chapter count appear straight away.

Choose paper, margins and type size

The book is laid out with justified text, hyphenation and proper orphan and widow control.

Print, and choose “Save as PDF”

Your browser writes the PDF itself, with the fonts embedded correctly.

FAQ

Questions about EPUB & PDF

Why a print dialog instead of a download button?

Because it produces a better file. Your browser contains a real typesetting and PDF engine with access to every font installed on your machine. In the dialog, set the destination to “Save as PDF” rather than a printer, and the file is written to disk exactly as you would expect.

Will Vietnamese or Chinese text come out right?

Yes — that is the main reason for this approach. JavaScript PDF writers must embed a font file for every script they support, which either bloats the page or drops characters silently. Your browser already has the fonts installed, so the text renders correctly whatever the writing system.

Can I change the page size?

Yes: A4, US Letter, A5 and B5, each with your own margins and type size. A5 at 10pt with narrow margins is close to a mass-market paperback; A4 at 14pt with wide margins is a large-print edition.

Do images survive?

Yes. Images stored inside the EPUB are rendered by the browser alongside the text and are embedded in the PDF it writes.

How do I do this on a phone?

Both iOS and Android can save a printed page as a PDF from the share or print sheet. The layout step is identical; only the final save differs, and your phone will offer “Save to Files” or a similar destination.

Why does my PDF look different from the publisher's edition?

Because the publisher's PDF was designed page by page by a typesetter, and this is generated from the ebook's markup. The words are the same and the reading is comfortable, but line breaks, page breaks and any decorative page furniture will differ.

Can I convert an EPUB I bought from a store?

Only if it is DRM-free. A book locked to a store account cannot be opened by this tool, and removing DRM is not something we support. Books from Project Gutenberg, Standard Ebooks, most indie publishers and your own manuscripts all work.

Or read it in two languages instead

A bilingual EPUB puts the original and the translation side by side, paragraph by paragraph — and you can still export a PDF afterwards.
