Compress an image online

Shrink the file size of JPG, PNG, or WebP images without losing much visible quality — ideal for web and email.

Reduce the file size of a JPG, PNG, or WebP image while keeping it looking sharp — see exactly how many kilobytes you saved.

How image compression works here

The image is re-saved at the quality you pick using format-appropriate settings: JPG and WebP use lossy compression, where lower quality means a smaller file; PNG is optimised losslessly. The tool reports the size before and after so you can judge the saving.

For photos, quality around 70–80 is usually indistinguishable from the original on a screen at a fraction of the size.

Pixels matter more than quality

A 4000-pixel-wide phone photo shown at 1200 pixels on a website is mostly wasted data. Resize Image first, then compress, for the biggest reduction.

How to use this tool

  1. Upload the image you want to shrink.
  2. Choose a quality level.
  3. Download the compressed image and see the size reduction.
