Image Compress

Higher = better quality, bigger file. PNG uses internal mapping to 0-9.

Note: PNG compression using PHP-only methods is limited. For best PNG results install pngquant or optipng on the server and call it after GD saving.

How to use
  • Select an image and set quality.
  • For JPEG/WebP choose quality 60-85 to get good compression with acceptable quality.
  • For PNG, prefer converting to WebP for best compression if browser support is fine for your users.

If you want me to add server-side tools like pngquant, I can add optional execution (requires shell access).
