Compress image by percentage
Shrink an image by a percentage you choose — from a light 10% trim to an aggressive 95% reduction. Percentage compression is useful when you care about relative size rather than hitting an exact KB figure.
Drag the slider, preview the change, and download the smaller image without leaving your browser.
