Image Compressor Free Online

Compress JPG, PNG and WebP images free in your browser. No upload, no sign-up – files stay on your device.

Your image stays on your device: it is processed in your browser and never uploaded.

How to use it

  1. Choose a JPG, PNG or WebP image.
  2. Pick the quality (75 is a good start), and optionally convert to WebP or reduce the longest side.
  3. Click Compress, check how much smaller it is, then download.

Common questions

Is it free?
Yes. It is free with no sign-up and no watermark, as many times as you like.
Are my files uploaded?
No. Everything happens in your browser, so your files never leave your device.
Which formats are supported?
JPG, PNG and WebP. You can keep the format or save as WebP or JPG for a smaller file; WebP keeps transparency.
How much smaller will my image get?
Photos usually shrink by 50–80% at quality 75 with no visible difference. PNG is lossless, so saving it again rarely helps: choose WebP or JPG, or reduce the image size.
