Choosing an Ebook Format

Use EPUB when text should adapt to the reader's screen. Consider PDF when page layout must stay fixed for distribution or print.

Which format should you choose?

Choose by the role each file plays in your workflow.

  • Text adapts to the device → EPUB
  • Fixed pages and print → PDF
  • Check the reader and delivery platform

Separate reading experience from page layout

Reflowable EPUB adapts text to different screens. PDF preserves a fixed page layout. Choose according to the content and the target reading system.

Formats to consider

EPUB

Good for: Text-focused books on ebook readers

Less suitable for: Print delivery requiring exact page layout

PDF

Good for: Fixed-layout sharing and printing

Less suitable for: Reflowing long text on a small screen

Before you export

  • Test EPUB in the target reading systems.
  • Conversion to PDF may change reflow and accessibility.
