Frequently asked questions
Is this image compressor free?
Yes. You can compress images here for free without creating an account.
Are my images uploaded to a server?
No. The compression runs in your browser, so the image file is not sent to our server by this tool.
Which format should I choose?
WebP is a good default for smaller web images. JPG is useful for photos and PNG is useful when you need lossless output or transparency.
