How It Works
Our compressor uses the HTML5 Canvas API to reduce file sizes directly in your browser. When you upload an image, it's displayed as a preview, drawn onto a hidden canvas, and re-exported at your chosen quality level. Lower quality means smaller file size, but the difference is often invisible to the human eye. Since everything runs locally, your images never leave your device — complete privacy guaranteed.
