Which image formats are supported?

The skill supports WebP (as the default), PNG, and JPEG formats for both input and output.

How do I set my own default quality settings?

You can create an EXTEND.md file in either your project's .baoyu-skills/baoyu-compress-image/ directory or your user home directory to define custom quality and format defaults.

Will my original files be deleted?

By default, the tool replaces the original file with the compressed version. To keep the original, use the --keep or -k flag during execution.

What tools are required for this skill to work?

It uses a fallback system to find the best available tool on your machine, checking for sips (macOS), cwebp, ImageMagick, and Sharp in that order.

Can I process multiple images at once?

Yes, you can provide a directory path and use the --recursive or -r flag to process all images within that folder and its subdirectories.
