How to convert EPUB to PDF
- Choose your .epub file. The title, author, cover and number of chapters appear, so you know it opened correctly.
- Pick the page size (A5, 6 × 9 in, A4, US Letter or A6), the margins and the text size. Leave page numbers on if you plan to print.
- Press Convert to PDF. Each chapter is laid out in turn; the PDF downloads when it's ready, with a preview of its first pages.
How the book is laid out
Your browser lays out each chapter with the book's own style sheet, the same way a reading app would, at the width of the page's text area. The chapter is then cut into pages between lines, never through a line of text or a picture, and a heading is kept with the line that follows it. Every word is placed in the PDF exactly where the browser put it. EPUB 2 and EPUB 3 books both work, including fixed-layout picture books, where each page keeps its own design and is scaled to fit the paper, and fonts the publisher has scrambled for embedding, which are restored as the EPUB standard describes.
Example: a novel on A5 pages
An A5 page is 419.5 × 595.3 points (148 × 210 mm). Normal margins of 18 mm take 51.0 points from each side, which leaves a text area of 317.5 × 493.2 points. A CSS pixel is 0.75 points, so the book is laid out 423 pixels wide and 657 pixels tall per page, and body text set at the usual 16 pixels prints at 12 points. With Larger text (115%) the same page is laid out 368 pixels wide and everything is scaled up by 1.15, so the body text prints at 13.8 points and there are fewer words to a line.
Tips
- For a printed booklet, choose A5 and print two pages per sheet on A4 (or 6 × 9 in on Letter).
- If a chapter starts with a cover picture already, the extra cover page is skipped automatically; untick Cover as the first page to leave it out anyway.
- Very long books take longer: a few hundred pages usually takes well under a minute on a laptop, longer on an older phone. You can cancel at any time.
