Add Watermark

python scripts/main.py watermark ./images/ --logo logo.png --position bottom-right

python scripts/main.py convert ./images/ --format webp
python scripts/main.py convert ./images/ --format avif --quality 80

Examples

Example 1: Prepare Product Images for E-commerce

# Remove backgrounds
python scripts/main.py remove-bg ./raw-products/ --output ./transparent/

# Resize to standard size
python scripts/main.py resize ./transparent/ --width 1000 --height 1000 --fit contain

# Compress for web
python scripts/main.py compress ./transparent/ --quality 85 --format webp

# Output: ./transparent/*.webp (optimized, transparent background)

Example 2: Social Media Image Kit

# Create multiple sizes from one source
python scripts/main.py resize hero-image.jpg --format instagram --output hero_ig.jpg
python scripts/main.py resize hero-image.jpg --format linkedin --output hero_li.jpg
python scripts/main.py resize hero-image.jpg --format twitter --output hero_tw.jpg
python scripts/main.py resize hero-image.jpg --format facebook --output hero_fb.jpg

# Or batch process entire folder for one platform
python scripts/main.py resize ./campaign-images/ --format instagram --output ./instagram/

Example 3: Website Image Optimization

# Convert all images to WebP
python scripts/main.py convert ./website-images/ --format webp --quality 80

# Ensure no image exceeds 200KB
python scripts/main.py compress ./website-images/ --max-size 200

# Results in 60-80% smaller file sizes
