Frequently asked questions

How do I compress a photo to exactly 50KB?
Enter 50 KB as the target. The tool adjusts compression to land at or under that size.
Why does my image look soft at a very small size?
Hitting a very small KB target forces heavier compression. Resize the image smaller first so it can reach the target with less quality loss.
