Why Convert EPUB to MOBI?

Older Kindle Compatibility

Kindles manufactured before 2022 don't support EPUB natively. MOBI is the traditional Kindle format that works on every Kindle model ever made — including Paperwhite (1st-10th gen), Voyage, Oasis, Keyboard, and basic Kindle.

Send to Kindle Email

MOBI files can be emailed directly to your Kindle's email address (found in Settings → My Account → Send-to-Kindle Email) for wireless delivery. This works on all Kindle models.

Sideloading via USB

MOBI files can be transferred to any Kindle via USB cable — just copy to the "documents" folder. This works even without WiFi.

Do You Still Need MOBI?

Amazon has been phasing out MOBI in favor of EPUB and KPF formats:

• Kindles 2022+ support EPUB natively via Send to Kindle
• Send to Kindle service stopped accepting MOBI uploads in 2023
• Kindle Direct Publishing no longer accepts MOBI for new books

If you have a newer Kindle (2022+), you can use EPUB directly. For older Kindles, MOBI remains the only option for sideloaded e-books.

Frequently Asked Questions

Will formatting be preserved?

Yes — basic formatting (headings, paragraphs, bold, italic, images, chapter structure) is preserved. Complex CSS styling may render slightly differently on Kindle.

Can I convert DRM-protected EPUB files?

No. DRM-protected e-books (from Adobe Digital Editions, Kobo, etc.) cannot be converted. Only DRM-free EPUB files can be converted.

Do newer Kindles support EPUB?

Yes — Kindles from 2022 onward support EPUB. For these devices, you may not need to convert to MOBI at all.

Is it free?

Yes. Completely free with no watermarks, no sign-up required.

Does it work on mobile?

Yes. Works in any modern browser on all devices — no app installation required.
