How much smaller will my images get?

Phone photos often shrink by 60–90% with no visible difference. PNG screenshots and graphics usually shrink by 50–80%.

Can I compress an image to a specific size like 100 KB?

Yes. Choose Target size and enter the size in KB, or use one of the presets. Each image is saved at that size or smaller.

Does compression keep PNG transparency?

Yes. PNGs are compressed with smart colour reduction (pngquant) that keeps transparency.
