Free image compression that runs locally
Upload one or more images and choose the output quality. The tool uses the browser's Canvas API to decode, resize, and encode images. Modern browsers support exporting canvas content as common formats such as JPEG and WebP.
JPG vs WebP
JPG is a familiar choice for photographs and broad compatibility. WebP can offer efficient compression and is widely supported by modern browsers. PNG is best when you need lossless-style output or transparency, although changing a PNG to JPG removes transparency.
Private by design
Images are processed on your device. That means you can use the tool for photos and documents without sending them to a remote compression service.
