Baoyu Compress Image

Compresses and converts images to WebP, PNG, or JPEG using whichever optimizer is available on your machine.

UtilitiesBeginner★ 24,749⑂ 2,764AI score 7/10Last updated: Jul 4, 2026

What it does

Compresses images to WebP (default), PNG, or JPEG. It auto-detects the best available tool in the order sips → cwebp → ImageMagick → Sharp, so it works with little to no setup.

  • Control quality (0–100), output path, and target format
  • Batch process folders, including subfolders with -r
  • Preserve originals with --keep, emit machine-readable results with --json
  • Pin default format, quality, and keep-original policy via EXTEND.md at project, XDG, or home scope

Who it's for

  • Writers and documenters who need lighter screenshots
  • Web developers bulk-converting assets to WebP for faster page loads
  • Content creators tired of manually optimizing images

Examples

  1. "Compress this screenshot" → image.png becomes image.webp with output like 245KB → 89KB, 64% reduction
  2. "Recursively compress ./images at quality 75" → handles nested folders in one pass
  3. "Keep PNG format and don't delete the original" → runs with -f png --keep for a safe optimization
