Supports: EPUB
EPUB is a reflowable ebook format — text rewraps to fit whatever screen it lands on. PDF is the opposite: a fixed page that looks identical everywhere and prints exactly as shown. Converting EPUB to PDF freezes the book onto a chosen page size (A4 by default), which is ideal for printing, annotating, or sharing a file anyone can open without an e-reader app. The trade-off: text no longer reflows, so a fixed PDF reads less comfortably on a small phone than the original EPUB did.

|---|---|---|
| Screen (Best) | Highest image quality, larger file | Reading on a monitor or tablet, image-heavy books |
| Ebook | Moderate image downsampling | A balanced, email-friendly file size |
| Printer | Tuned for paper output | Printing at home or at a copy shop |
| Prepress | Preserves color fidelity for print production | Sending to a professional print service |
| Default | Standard balance of size and quality | A general-purpose PDF when unsure |
EPUB is built for dynamic layout — the W3C EPUB 3 specification describes content as "intended to be formatted on the fly rather than being typeset in a paginated manner in advance." PDF (ISO 32000) is a fixed-page format, so the conversion has to "freeze" the flowing text onto set pages. That is exactly why a PDF prints and shares predictably, but it also means the text can no longer rewrap to a smaller screen.
Text content and the basic structure — headings, paragraphs, bold and italic, and embedded images — carry over. In our testing, a plain-prose EPUB converted cleanly into flowing A4 pages with chapter headings intact. Highly designed EPUBs (comics, magazines, fixed-layout children's books with precise positioning) are the ones most likely to shift, because their pixel-exact placement does not always survive the move to a standard page size.
By default the book is laid out on A4 portrait pages, which suits most reading and printing. Desktop tools such as Calibre default to U.S. Letter instead — if you are printing in North America, Letter may waste less paper, so check the paper your printer is loaded with before a long print run.
Choose the "Ebook" compression preset, which downsamples images to a lighter size. If the PDF is still too large for an attachment limit — Gmail caps attachments at 25 MB — run the file through our PDF compressor afterward to squeeze it further without re-converting.
Yes. Your EPUB is uploaded over an encrypted connection, converted on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. Need the reverse direction? Use our PDF to EPUB converter to turn a PDF back into a reflowable ebook, or convert MOBI to PDF for Kindle-format books.
