'''Lepton''' is a special-purpose compression algorithm and file format, developed by Dropbox. It only compresses [[JPEG]] files.<br />
<br />
== Identification ==<br />
Files begin with {{magic|0xcf 0x84}} (lepton), or {{magic|0xce 0xb6}} (zlib compressed lepton).<br />
<br />
The lepton software appears to also support a format it calls "UJG", which starts with ASCII "{{magic|UJ}}".<br />
