Compression runs on your device using the browser's image engine. Your photo is never uploaded to a server.

About the Image Compressor

A modern phone photo can easily exceed six megabytes, which is far more than a web page, a job application form or a messaging app needs. The Image Compressor re-encodes your picture at a quality level you choose and shows the size saved before you commit to the download.

Because you can see the compressed preview next to the original size, it is easy to find the point where the file is small enough but the picture still looks right. Most photographs survive a drop to around seventy percent quality with no visible difference on screen.

How to use the Image Compressor

  1. 1Choose an image file, or drop it onto the upload panel.
  2. 2Move the quality slider; lower values mean smaller files.
  3. 3Optionally pick an output format, such as WebP for the smallest result.
  4. 4Compare the original and compressed sizes shown beneath the preview.
  5. 5Download the compressed image when you are happy with it.
