Frequently Asked Questions

How do I reduce a photo to 50 KB without losing quality?

Choose the 50 KB target. The tool first lowers JPEG quality step by step, then reduces the resolution only if necessary, so faces and text stay as sharp as possible.

What format is the result?

JPG, the format accepted by almost every online form. Transparent PNG areas become white.
