  1. Add your .SNB file - drop it in the box above or click to browse.
  2. Convert it to .MOBI in a few seconds.
  3. Download your new .MOBI file.

What to expect

  • MOBI does not support all EPUB formatting features; complex layouts or custom fonts from the source .snb may render differently in the output.
  • The .snb extension is also used by Samsung S Note (early Galaxy Note devices); those are note-taking files, not ebooks, and cannot be converted to MOBI.
  • For modern Kindles running firmware 5.10.3 or later, converting to EPUB instead of MOBI is usually a better choice - Send to Kindle supports EPUB directly.

Frequently asked questions

Do I need to install anything to convert SNB to MOBI?
No - our free converter above handles it without any install. If you prefer to convert locally, Calibre is the only desktop tool that reads .snb.
Will images and the table of contents transfer to the MOBI file?
Yes. Calibre preserves embedded images, cover art, and chapter structure when converting from .snb.
Is EPUB a better output format than MOBI?
For most modern e-readers, yes. Choose MOBI only if you specifically need the older Kindle-native format; otherwise EPUB has broader support.
My `.snb` file fails to convert - what could be wrong?
If the file came from a Samsung Galaxy Note device, it is an S Note file, not a Bambook ebook, and is not supported. Only Bambook .snb ebook files can be converted to MOBI.
