How it works

Upload any image and choose your resize constraints and quality level. The tool uses browser-image-compression — a WebWorker-based library — to resize and compress the image entirely inside your browser. Nothing is sent to any server.

Resize modes

  • Max dimension — scales the image so that neither width nor height exceeds the given value, preserving aspect ratio.
  • Exact width — resizes to the specified width, preserving aspect ratio.
  • Exact height — resizes to the specified height, preserving aspect ratio.

Output formats

  • WebP — best compression for photos and graphics. Supported in all modern browsers.
  • JPEG — universal compatibility, ideal for photographs.
  • PNG — lossless compression, best for screenshots and images with transparency.
