Frequently asked questions
Is this image compressor really free?
Yes. There are no limits, watermarks or sign-ups. The compression runs entirely in your browser, so it costs us nothing to serve you.
Are my images uploaded to a server?
No. Your images are processed locally on your device with the browser's built-in codecs and never leave your computer.
Which formats can I compress?
JPG, PNG and WebP are supported. For JPG and WebP you can control the quality level; PNG is re-encoded losslessly.
