Learn the key EPUB vs. PDF differences, advantages and best use cases for each file format.

The key EPUB vs. PDF difference is that EPUB uses a flexible, reflowable layout for digital reading, while PDF preserves a fixed layout for consistent viewing, sharing, and printing. This core distinction influences each format’s file size, compatibility, interactivity, editability, and security. In turn, choosing the wrong format can lead to several issues, such as excessive zooming on small screens or content breaking into awkward flows.

In this guide, we will explain EPUB vs. PDF differences in more detail and cover common use cases for both formats to help you choose the best one for your needs.

An EPUB file uses reflowable text to adapt to different screen sizes and devices, making it suitable for reading long-form content like e-books and textbooks.

A PDF file is a digital document format that preserves layout, formatting, and design so the content looks the same across devices and when printed.

EPUBs are typically smaller than PDFs, which makes them a better choice for sharing and storage; on the other hand, they don’t have the same universal compatibility and consistency as PDFs.

To decide whether EPUB or PDF is a better fit, you should think about whether consistent formatting, printing, sharing, or flexible digital reading is the priority.

If you want to distribute content through e-book platforms with account-based DRM, EPUB is often the preferred format; PDF is suitable for creating documents to collect signatures or apply them.

PDF/UA (ISO 14289) for universal accessibility and assistive technology

PDF/R (ISO 23504) for multi-page raster-image documents

PDF/E (ISO 24517) for engineering workflows

official documents, contracts, resumes, and reports
