Optimage optimizes JPEGs and PNGs by losslessly recompressing them and removing
unnecessary metadata (EXIF, comments, etc), making the web faster and your repo



* `jpegtran <>`_
* `jpegoptim <>`_


* `pngcrush <>`_
* `optipng <>`_

Example usage

$ optimage test_data/valid1.png
File can be losslessly compressed to 67 bytes (savings: 52 bytes = 43.70%)
Replace it by running either:
optimage --replace test_data/valid1.png
optimage --output <FILENAME> test_data/valid1.png

$ optimage --replace test_data/valid1.png
File was losslessly compressed to 67 bytes (savings: 52 bytes = 43.70%)

$ optimage --output /tmp/valid1.png test_data/valid1.png
File was losslessly compressed to 67 bytes (savings: 52 bytes = 43.70%)
