PDF vs EPUB

PDF vs EPUB: what authors need to know before exporting a book.

Print books and ebooks do not use the same layout logic. A good publishing workflow treats PDF and EPUB as related outputs with different checks.

Print PDF

PDF is about fixed pages.

A print PDF preserves page size, margins, typography, image placement, page numbers, headers and footers. That makes it suitable for print interiors and proofing, but it also means every page geometry decision matters.

  • Trim size and margins are central.
  • Image resolution and bleed affect print quality.
  • Final page count affects gutter and cover setup.

EPUB ebook

EPUB is about structured reflow.

An EPUB adapts to the reader’s device, font size and reading app. That makes semantic structure, clean chapters, metadata, table of contents and image behavior more important than exact page placement.

  • Chapters and headings should be consistent.
  • Navigation and metadata need care.
  • Images should be optimized for screen reading.

Format decisions

Use the right checks for the right output.

PDF checks

Trim size, margins, gutter, page count, bleed, headers, footers and image resolution.

EPUB checks

Metadata, table of contents, chapter structure, semantic headings, links and validation.

Shared checks

Clean manuscript text, correct chapter order, image references and front/back matter.

FAQ

PDF and EPUB questions

Is PDF or EPUB better for publishing?

They solve different problems. PDF is used for fixed print interiors and proofs. EPUB is used for reflowable ebooks that adapt to reading devices.

Can one manuscript produce both PDF and EPUB?

Yes, but the export settings and checks are different. Print needs page geometry; EPUB needs structure, metadata, navigation and reflow-friendly content.

Why should authors proof both formats separately?

A page that looks good in PDF can still behave poorly as a reflowable ebook, and an EPUB that reads well may not meet print requirements.
