FAQ
How image compression works
Will compression always make the file smaller?
No. PNG or already-optimized images can become larger. The result shows the real size so you can choose the better file.
Does the image leave my device?
No. The image is decoded, drawn, and exported in this browser tab. The original file is never overwritten.
