What to expect
- DRM blocks conversion - AZW3 files purchased from the Kindle Store are locked and cannot be converted by Calibre or any other tool.
- Complex CSS styling, fixed layouts, drop caps, and custom fonts are lost because FB2 is a simpler semantic format; plain prose converts well.
- Images from the AZW3 are included in the FB2 output, but their placement may shift.
Frequently asked questions
Can I convert a Kindle purchase to FB2?
No. Amazon-purchased AZW3 files are DRM-locked; only DRM-free AZW3 files can be converted.
Will images survive the conversion?
Yes - Calibre embeds images as base64 data inside the FB2 file, which is the standard FB2 approach.
How much formatting is lost?
Simple prose and chapter headings carry over cleanly; complex CSS, drop caps, and precise spacing are lost because FB2 does not support them.
Can I compress the output FB2 file?
Yes - FB2 is XML-based and compresses well; many e-readers also accept
.fb2.zip directly.Programs that convert AZW3: Hamster Free eBook Converter · Calibre · Calibre for Mac · Calibre for Linux
