How does the image compressor work?
Unlike most online tools, our compressor runs entirely inside your browser using the HTML5 Canvas API. Your image is never uploaded to any server — it stays on your device throughout the entire process. This means it works even offline, and there are no privacy concerns.
We redraw your image at the quality level you choose and encode it as JPG or WebP. For PNG files, JPG compression typically reduces file size by 60–80%. WebP produces the smallest files with the best quality-to-size ratio and is supported by all modern browsers.
