Utility Scripts

optimize-images.py

Compresses images in the assets/images/ directory to reduce file sizes without significant quality loss.

Requirements:

pip install Pillow

Usage:

# Optimize all images in assets/images/
python scripts/optimize-images.py

# Check what would be optimized without modifying files
python scripts/optimize-images.py --check-only

# Optimize with custom JPEG quality (1-100)
python scripts/optimize-images.py --quality 90

# Optimize images in a different directory
python scripts/optimize-images.py --path path/to/images

What it does:

• PNG files: Lossless optimization using PIL’s optimize flag
• JPEG files: Quality-based compression (default: 85)
• Only replaces images if savings > 5%
• Preserves original image dimensions and format
