ImageMagick 7+ Usage

Critical: Use `magick`, Not `convert`

In ImageMagick 7+, the convert command is deprecated. Use magick instead:

# Wrong (generates warnings)
convert input.png output.jpg

# Correct
magick input.png output.jpg

# Also correct (explicit tool)
magick convert input.png output.jpg

Common Operations

Format Conversion

magick input.png output.jpg
magick input.jpg -format webp output.webp

Resize

magick input.jpg -resize 50% output.jpg
magick input.jpg -resize 1920x1080 output.jpg
magick input.jpg -resize 1920x1080^ output.jpg  # Minimum dimensions

Compress/Quality

# JPEG quality (0-100, higher is better quality, larger file)
magick input.png -quality 85 output.jpg

Strip Metadata

magick input.jpg -strip output.jpg

Batch Processing

for file in *.png; do
  magick "$file" "${file%.png}.jpg"
done

Key Flags

Flag	Description
`-quality N`	JPEG compression (0-100)
`-resize WxH`	Resize to dimensions
`-strip`	Remove metadata
`-format FMT`	Specify output format
`-auto-orient`	Fix orientation from EXIF
`-compress type`	Compression type (lossy, lossless, none)

ImageMagick 6 vs 7

IM 6: Uses convert, mogrify, identify as separate commands
IM 7: All tools available via magick <tool> (e.g., magick convert, magick mogrify)
IM 7 standalone commands still work but emit deprecation warnings

Version Check

magick --version

Important Notes

Always quote filenames with spaces: "$file"
Use -strip to reduce file size by removing EXIF/metadata
Default JPEG quality is 92; use -quality 85 for web images
IM 7 maintains backward compatibility but warns about deprecated usage
