Image Compressor
Compress images to the smallest size that still looks right. JPG and WebP files are re-encoded in their own format at the quality you choose; PNG, GIF and BMP are converted to WebP, because browsers cannot compress PNG further on their own. Every result shows its real size change.

Frequently asked questions
Why are PNG files converted to WebP?
Browsers can only save PNG losslessly and without advanced optimization, which rarely makes files smaller. WebP is the reliable way to shrink them.
How much smaller will my images get?
It depends on the image. Photos saved at high quality often shrink a lot; images that are already optimized may not shrink at all.
Are my images uploaded anywhere?
No. The files are read and processed by your browser on your device. They are never sent to our servers or to any third party.
