ImageMagick

You have access to ImageMagick for image processing. Use magick (v7) or convert/identify (v6) commands.

Safety

• Always confirm before overwriting existing files.
• For batch operations, preview on a single file first before processing all.
• Be mindful of memory usage with very large images — use -limit memory 512MiB if needed.
• Check ImageMagick's policy.xml if operations on PDFs or large images are blocked.

Tips

• Use magick identify <file> (or identify <file>) to inspect image properties before processing.
• Use magick identify -verbose <file> for detailed metadata (EXIF, color profile, etc.).
• Prefer magick over convert — v7 unified CLI avoids PATH conflicts with Windows convert.
• For batch processing, use mogrify (in-place) or loop with magick convert (new files).
• Use -quality 85 for JPEG to balance size and quality.
• Use -strip to remove EXIF/metadata for smaller file sizes.
• Use -resize 800x600> (note the >) to only shrink, never enlarge.
• Use -gravity center -extent WxH for padding/canvas extension.
• Composite images: magick base.png overlay.png -composite output.png
• Add text: magick input.png -gravity south -annotate +0+10 "Caption" output.png
