EPUB to AZW3 — Convert EPUB to Kindle Format

Older Kindle devices do not support EPUB natively, requiring conversion to Amazon's AZW3 format. The MyPDF EPUB to AZW3 converter makes your EPUB ebooks Kindle-ready in seconds.

How to Convert EPUB to AZW3

1. Upload your EPUB file by dragging it onto the converter.
2. Configure output options like metadata (title, author) and cover image.
3. Download your AZW3 file and transfer it to your Kindle via USB or email.

Practical Tips

• Send to Kindle via email. After converting, email the AZW3 file to your Kindle's unique email address for wireless delivery.
• Verify the cover image. Some EPUB cover images may need to be re-embedded during conversion. Check that it displays correctly on your Kindle.
• Test on your specific Kindle model. AZW3 rendering can vary slightly between Kindle Paperwhite, Oasis, and Fire devices.

Will the table of contents work?

Yes. The EPUB's navigation structure is converted to a Kindle-compatible table of contents that works with the Kindle's built-in navigation.

Can I convert DRM-protected EPUBs?

No. DRM-protected ebooks cannot be converted due to digital rights restrictions. Only DRM-free EPUBs can be processed.

Do newer Kindles need AZW3?

Kindle devices from 2022 onward support EPUB natively. If you have an older Kindle, AZW3 conversion is still necessary.
