EPUB to PDF Converter

EPUB books reflow to fit a phone or e-reader, which is great for reading but useless when you need fixed pages — to print a chapter, annotate it on a tablet, or send it to someone without an e-book app. This converter lays the book out as a real PDF: each chapter starts on a new page, headings, lists, quotes, links and pictures are kept, and chapter bookmarks and page numbers are added. It works on DRM-free books, entirely in your browser.

How to use this tool

1. Choose the .epub file (it must be DRM-free).
2. Pick the page size, font and text size — A5 with 11 pt reads like a printed paperback.
3. Choose margins, justification and whether to include pictures, the cover, bookmarks and page numbers.
4. Download the PDF.

Formula

Chapters are read in the order of the book's spine (its reading order). Lines are filled word by word: a word goes on the current line if the line width plus a space plus the word stays within the text width; otherwise a new line starts. Justified lines share the leftover width equally between the spaces.

Text width = page width − 2 × margin. Line height is 1.45 × the text size for paragraphs and 1.25 × for headings (1.9 × the text size for a top-level heading). Pictures are shrunk to the text width and never enlarged.

Example

A 60,000-word novel converted to A5, 11 pt Times with 15 mm margins, gives roughly 180–220 pages: up to 31 lines of about 12 words on a full page (fewer words when the book has many short paragraphs or lines of dialogue), with every chapter starting on a fresh page and a bookmark for each chapter title from the book's table of contents.
