Frequently asked questions
How much smaller will my image get?
It depends on the image and quality setting, but photos typically shrink by 40–80% with little visible difference.
Does compression happen on your servers?
No — compression is done in your browser, so nothing is uploaded and there are no limits.
Will PNG transparency be kept?
Yes. PNG output keeps its alpha channel; for maximum compression, try converting to WebP instead.
