Free online image compressor compress JPEG, PNG & WebP

Compressify reduces image file sizes by up to 90% without visible quality loss. Unlike most online compressors that upload your files to a remote server, everything here runs in your browser using the Canvas API. Your photos never leave your device verifiable via the browser DevTools Network tab.

Use the quality slider to control how aggressively files are compressed. At 80–85%, the visual difference is imperceptible to most people while the file size reduction is dramatic. Converting to WebP gives you an additional 25–35% reduction on top of JPEG at equivalent visual quality.

Why WebP is the best choice for web images

WebP is supported by all modern browsers Chrome, Firefox, Safari, and Edge. Switching your website images to WebP is one of the fastest ways to improve Google PageSpeed scores and Core Web Vitals, both confirmed ranking factors in Google Search.
