What the Image Compressor does
The image compressor shrinks your images to reduce page weight and improve load speed, all without uploading them to a server.
How it works
The tool redraws your image to a canvas and re-encodes it at your chosen quality and format. Lower quality means a smaller file, and switching to WebP often cuts size further at the same visual quality.
Because everything happens in your browser, your images stay private and the process is instant.
