How much can I reduce image file size?

Results vary by image content and format. JPEG images can often be reduced by 50–80% with minimal visible quality loss. PNG compression depends on how much redundant data is in the image.

Does compression affect image quality?

You control the quality level with a slider. Lower quality means smaller files. For most web use cases, a quality setting of 70–85% is imperceptible to the human eye.
