Frequently asked questions
How much smaller will my images get?
Photos usually shrink by 50–80% at 75–85% quality with no visible difference. Screenshots and graphics vary more.
Why didn't my PNG get smaller?
PNG is lossless, so re-saving it in the browser barely changes the size. Convert it to WebP, which keeps transparency, or to JPG if it has none.
What does target size do?
It finds the highest quality that fits under the size you set. If an image can't get there, limit its longest side as well.
Does compression change the dimensions?
No, unless you turn on Limit longest side. Then large images are scaled down proportionally.
Are my images uploaded?
No. Compression happens in your browser and files never leave your device.
Need more than a quick edit?
