What it does

  • Triggers on requests like "compress image", "optimize image", "convert to webp", or "reduce file size".
  • Auto-selects the best available compressor: sips → cwebp → ImageMagick → Sharp.
  • Supports format (webp/png/jpeg), quality 0–100, keeping the original, recursive folder processing, and JSON output.
  • Lets you pin defaults (format, quality, keep-original) through an EXTEND.md file at project, XDG, or home scope.

Who it's for

  • Writers and bloggers shrinking screenshots before publishing.
  • Web developers optimizing assets for faster page loads.
  • Anyone who needs to batch-convert hundreds of images at once.

Usage examples

  1. "Compress screenshot.png to WebP" → image.png → image.webp (245KB → 89KB, 64% reduction)
  2. "Recursively compress everything in ./images at quality 75"
  3. "Optimize but stay PNG and keep the original" (-f png --keep)
