About This Tool
Image Compressor reduces file size for PNG, JPG, WebP, and other formats by adjusting compression quality. Compress a single image or a whole batch at once, with a live size comparison before downloading.
For JPG and WebP, lower quality values produce smaller files with some visual loss. PNG compression is lossless and reorganizes data without discarding pixels. WebP typically achieves 25-35% smaller files than JPEG at equivalent quality.
All compression happens in your browser using the HTML5 Canvas API. No images are uploaded anywhere. Your files stay private on your device.
