Optimage optimizes JPEGs and PNGs by losslessly recompressing them and removing unnecessary metadata (EXIF, comments, etc), making the web faster and your repo smaller.
$ 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%)
You can install, upgrade or uninstall optimage with these commands:
$ pip install optimage $ pip install --upgrade optimage $ pip uninstall optimage
You'll also want to install (note that libjpeg-turbo-progs below is for jpegtran):
$ apt install libjpeg-turbo-progs jpegoptim pngcrush optipng zopfli
Python 2.7, 3.3, 3.4 and 3.5 are supported.
