About this tool

A private browser-based image compressor for reducing photo and graphic file sizes without sending files to a server. Quality, format, transparency and batch output are controlled on your device.

Example: lower JPEG quality to reduce a 2 MB photo before emailing it. PNG screenshots may already be smaller than a re-encoded copy.
