Image Compressor is a free online tool that reduces image file sizes by converting them to optimized JPEG format with adjustable quality. Simply upload any image, adjust the quality slider to find the perfect balance between file size and visual quality, and download the compressed result. The tool shows a side-by-side comparison of your original and compressed images with detailed size information. You can see exactly how much space you're saving — typical photos can be reduced by 50-80% with minimal visible quality loss at quality settings between 60-80%. All compression happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy. The compressed output is in JPEG format, which provides excellent compression for photographs and images with gradients.
