Commands

Resize Images

python scripts/main.py resize ./images/ --width 1200 python scripts/main.py resize ./images/ --format instagram # 1080x1080 python scripts/main.py resize ./images/ --format linkedin # 1200x627

Compress Images

python scripts/main.py compress ./images/ --quality 80 python scripts/main.py compress ./images/ --max-size 500 # Max 500KB

Remove Background

python scripts/main.py remove-bg photo.jpg python scripts/main.py remove-bg ./products/ --output ./transparent/

Add Watermark

python scripts/main.py watermark ./images/ --logo logo.png --position bottom-right python scripts/main.py watermark ./images/ --text "© 2024 Company" --opacity 0.3

Convert Format

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
