Frequently asked questions
Why did my image come back "already optimized"?
Some images, especially already-compressed PNGs, get larger when re-encoded. In that case the tool keeps the original. Try JPG or WebP as the target, or smaller max dimensions.
How do I make a PNG smaller?
Reduce the maximum dimensions or convert it to JPG or WebP. Photos shrink far more in those formats.
