How to compress an image for free
Pick one or several photos, drag the quality slider, and cutbg re-encodes them to smaller files — instantly, with a live before/after size. Drop a whole batch and download them all as a zip.
Does my image get uploaded?
No. Compression runs entirely in your browser using a web worker, so the files never leave your device and there's no upload wait.
