Frequently Asked Questions
How do I convert an ebook for free?
Pick the tool that matches your formats (for example EPUB to MOBI), upload your ebook, pass the quick security check, and download the converted file. No sign-up, no watermarks, and no fees.
Which format should I use for my Kindle?
Modern Kindles work best with AZW3 (KF8). Older Kindle devices use MOBI. If you are unsure, MOBI offers the widest backward compatibility.
What is the difference between EPUB, MOBI and AZW3?
EPUB is the open standard used by most readers (Kobo, Apple Books, Google Play Books). MOBI is Amazon’s older format, and AZW3 (KF8) is Amazon’s modern format with richer styling.
Do these tools remove DRM?
No. Our converters only work with DRM-free ebooks. They never bypass or strip digital rights management.
Is there a file size limit?
You can convert ebooks up to 250 MB, far larger than virtually any text-based book.
Are my ebooks private?
Yes. Every conversion runs in an isolated, in-memory process. Your file is never stored, never shared, and is deleted the instant your download is ready.
