Why use these image tools?

  • Private by design — images are processed on your device, so personal photos and screenshots never hit a server.
  • Practical for the web: compress to cut page weight and convert to WebP for smaller, faster-loading images.
  • OCR turns a screenshot or scan into selectable, copyable text without any external service.
