About the MOBI format

MOBI — Mobipocket eBook

MOBI is the ebook format developed by Mobipocket, which Amazon acquired to form the basis of Kindle formats. While largely superseded by Amazon's KFX and AZW3 formats on modern Kindles, MOBI files remain widely distributed and are supported by older Kindle devices.

Common uses

  • Kindle-compatible ebook distribution
  • Reading ebooks on older Amazon Kindle devices
  • Converting ebooks for Kindle compatibility
  • Self-publishing ebook workflows

About the BZ2 format

BZ2 — Bzip2 Compressed File

BZ2 is a single-file compression format using the bzip2 algorithm (Burrows-Wheeler transform + Huffman coding). It consistently achieves 10-15% better compression ratios than gzip for text and source code, making it preferred for bandwidth-sensitive distributions. Like gzip, it compresses only a single file — directories must be bundled with TAR first.

Common uses

  • Compressing large text files and source code archives
  • Linux package distribution (.deb source packages)
  • Scientific data compression
  • Bandwidth-sensitive file distribution
