About:
ImageOptim is a macOS utility that optimizes images by removing unnecessary metadata and applying advanced compression algorithms. It reduces file sizes without noticeable quality loss, making images load faster on websites and take up less storage space. The tool supports multiple formats including PNG, JPEG, and GIF, and can process batches of files efficiently.
Key Features:
  • Lossless compression using advanced algorithms
  • Batch processing of multiple files and folders
  • Removes unnecessary metadata and color profiles
  • Supports PNG, JPEG, GIF, and WebP formats
  • Integration with Finder for drag-and-drop workflow
Use Cases:
  • Optimizing website images for faster page load times
  • Reducing storage space for photo libraries and design assets
Alternatives:
  • TinyPNG – Web-based service vs local app; requires internet connection
  • ImageAlpha – Specialized for PNG only vs ImageOptim's multi-format support
  • Squoosh – Web-based with visual comparison vs native macOS app
