What is the Image Compressor?
The ToolKy Image Compressor reduces the file size of your JPG, PNG and WebP images using a quality slider you control. You see the original size, the compressed size and the exact percentage saved before you download anything.
Large images are the number one cause of slow websites. Page speed affects your search ranking, your bounce rate and how many people ever see your content. A typical phone photo is three to six megabytes; the same image compressed sensibly is often under 300 kilobytes with no visible difference on screen.
Compression here runs entirely in your browser using the canvas API. Your images are never uploaded to a server, never stored and never seen by anyone else — which matters for client work, unreleased product shots and anything personal.
