About this tool

Smaller images load faster. This tool re-encodes your image on your own device, so the file is never uploaded.

How to use Image Compressor

  1. Choose or drop an image.
  2. Pick the output format and quality.
  3. Compare the sizes and download the compressed file.

Frequently asked questions

Is my image uploaded to a server?

No. All processing happens in your browser using the canvas API.

Which format compresses best?

WebP and JPEG give the smallest files for photos. Use quality 70 to 85 for a good balance.
