In today’s digital age, e-books have become a popular way to consume literature, technical manuals, and other reading materials. However, many documents are still distributed as PDFs, which aren’t always the most convenient format for e-readers. Converting PDFs to EPUB, a format optimized for e-book reading, is a great way to enhance your reading experience. In this article, we'll explore how to convert PDFs to EPUB online using the best tools available.

Why Convert PDFs to EPUB?

PDFs are designed for printing and maintaining fixed layouts, making them less flexible for e-readers. EPUB, on the other hand, is designed specifically for e-books, allowing text to be reflowed, resized, and adapted to different screen sizes. Converting PDFs to EPUB improves readability on devices like Kindle, iPad, and other e-readers.

Criteria for Selecting the Best PDF to EPUB Converters

When choosing a tool to convert PDFs to EPUB, consider the following criteria:

• Conversion Quality: Ability to retain the original content, formatting, and layout as much as possible.
• Ease of Use: User-friendly interface with a straightforward conversion process.
• Speed: Quick conversion times, especially for large documents.
• File Size Limits: Ability to handle large files effectively.
• Cost: Availability of free and paid options with various features.
• Security: Ensures the privacy and protection of uploaded files.
