A command line script that compresses image(s) as much as possible without losing quality or resolution. The script supports JPEG, PNG and WEBP image formats and is built using open-source modules.

• Python 3.x
• PIL (Pillow)

python compress_image.py -f [file or directory path] -q [quality]

• -f or --file: path of the image file or directory containing the images.
• -q or --quality: quality of compression from 0 to 100 (default is 95).
• -h: show help

python compress_image.py -f image.jpg -q 85 or python compress_image.py -f images_folder -q 75

The script only works for jpeg, png and webp files and you can extend it to other image file formats as well.
