Leanify is a lightweight lossless file minifier/optimizer. It removes unnecessary data (debug information, comments, metadata, etc.) and recompress the file to reduce file size. It will not reduce image quality at all.
- Support recursive minifying. (e.g. aPNGinside anAPKinside aZIP)
- Support a wide variety offile formats.
- Lightweight, one file, under 1MB, no external dependency.
- Everything is done in memory, no temporary files.
- Cross-Platform, support Windows, Linux, Mac.
- Support traverse directory recursively.
- Ability to identify file format by its data instead of name.
I'm not respossible for any consequence of using Leanify.
PLEASE BACKUP THE FILE BEFORE USING LEANIFY!
It is based onZIP.
Note that modifying files insideAPKwill break digital signature.
To install it, you'll have to sign it again.
If you don't want to modify any files insideAPK,use-d 1option.

Usage: leanify [options] paths
-i, --iteration <iteration> More iterations produce better result, but
use more time, default is 15.
-d, --max_depth <max depth> Maximum recursive depth, unlimited by default.
Set to 1 will disable recursive minifying.
-f, --fastmode Fast mode, no recompression.
-q, --quiet No output to stdout.
-v, --verbose Verbose output.
-p, --parallel Distribute all tasks to all CPUs.
--keep-exif Do not remove Exif.
