Lepton is a special-purpose compression algorithm and file format, developed by Dropbox. It only compresses JPEG files.

[edit] Identification

Files begin with 0xcf 0x84 (lepton), or 0xce 0xb6 (zlib compressed lepton).

The lepton software appears to also support a format it calls "UJG", which starts with ASCII "UJ".
