What is Image Compressor?
The Image Compressor shrinks file sizes of JPEG, PNG, and WebP images by up to 80% without noticeable quality loss. By applying smart chroma subsampling, metadata stripping, and quantization locally in your browser, your photos load faster on web pages without compromising privacy.
