img-compress#

Batch image compression tool based on Pillow(PIL).

Quick Usage#

bash

# Compress images over 100KB to 80KB
sudo python3 skills/img-compress/scripts/compress_img.py /path/to/images

# Custom target size (KB)
sudo python3 skills/img-compress/scripts/compress_img.py /path/to/images 150

Compression Rules#

• JPG/JPEG: Gradually reduce quality (85→50) + optimize until under target size
• PNG: Pillow PNG compression (limited), recommend pngquant for better results
• Files under target size are skipped
• Overwrites original files (in-place)

Dependencies#

• Python3
• Pillow: pip3 install Pillow
