File Size Filtering

Only compress files larger than 5MB

Only compress files smaller than 10MB

feather input_dir/ -r --max-size 10M -o output_dir/

Compress files between 5MB and 10MB

feather input_dir/ -r --min-size 5M --max-size 10M -o output_dir/

Quality Settings

# Set JPEG quality (1-100, default: 85)
feather input.jpg --jpeg-quality 90 -o output.jpg

# Enable PNG lossy compression with quality (1-100)
feather input.png --png-lossy --png-quality 80 -o output.png

# Set WebP quality (1-100, default: 80)
feather input.webp --webp-quality 85 -o output.webp

Image Resizing

# Resize to maximum width of 1920px
feather input.jpg --max-width 1920 -o output.jpg

# Resize to maximum height of 1080px
feather input.jpg --max-height 1080 -o output.jpg

# Set both width and height constraints
feather input.jpg --max-width 1920 --max-height 1080 -o output.jpg

# Only process JPEG files
feather images/ -r --glob-pattern "*.jpg" -o output/

# Process multiple patterns
feather images/ -r --glob-pattern "*.{jpg,jpeg,png}" -o output/
