  • Reflowable Text: EPUB supports dynamic text adjustment based on screen size.
  • E-reader Compatibility: Works seamlessly with popular e-readers.
  • Customizable Reading Experience: Readers can change fonts, spacing, and themes.
  • Smaller File Sizes: EPUBs often compress more efficiently than PDFs.
  • Accessibility Features: Better support for screen readers and accessibility options.

Converting a PDF into an EPUB not only enhances readability but also opens up possibilities for broader distribution and easier access across different platforms. For publishers, authors, educators, and students alike, mastering the process of PDF to EPUB conversion is crucial.
