On Androiddevices, reading such books can turn into a convenient process - if you choose the right application and customize it to your needs. However, many users encounter problems: from the lack of format support in standard apps to incorrect display of text on high-resolution screens.

In this article we will examine not only best applications for reading EPUB on Android, but also the nuances of setting them up - from choosing fonts to synchronizing bookmarks between devices.

And for those who prefer minimalism, here are instructions for reading EPUB through Google Play Books without third-party apps.

Why EPUB is better than PDF for reading on a smartphone

The main advantage EPUB over PDF — text adaptability to the screen size. Unlike the rigid layout of PDF, EPUB books automatically adjust to fit the width of your display, allowing you to change the font size without losing readability. This is critical for smartphones, where the screen is 2-3 times narrower than that of a tablet or e-reader.

Other advantages of EPUB:

  • 📱 Support hyperlinks and tables of contents (they often do not work in PDF).
  • 🎨 Custom styles: you can change the font, line spacing and background color.
  • 🔍 Text search works faster than in PDF.
  • 📚 Smaller file weight at the same content.

The only case when PDF is preferable is if the book contains complex tables, diagrams or layout (for example, mathematics textbooks or technical manuals). In all other situations, EPUB wins.
