Our free online image compressor offers a powerful, browser-based solution to reduce image file size by up to 80% without visible loss in quality.
Not all compression is created equal. Our photo optimization tool uses advanced "Smart Compression" algorithms that selectively remove metadata and apply subtle color quantization. The result?
