Compress Images Without Quality Loss
Large image files slow down websites and increase bandwidth costs. Our browser-based image compressor lets you reduce JPG, PNG, and WebP files by up to 90% without uploading a single byte to any external server. Everything is processed entirely using the HTML5 Canvas API in your own browser tab — your images never leave your device.
How Does Browser-Side Compression Work?
When you upload an image, it is decoded into a pixel array and re-drawn onto an invisible HTML5 Canvas element at your chosen maximum dimensions. The canvas is then re-encoded at your specified quality level (a number between 10% and 100%). Lower quality values discard more image data, producing smaller files. WebP and JPEG both support this lossy quality slider, while PNG uses lossless encoding.
