Compress Images Online — Free Image Compressor
Large images slow down websites, bloat emails, and eat storage on your phone. QuickPixel's image compressor fixes that without asking you to install anything: drop in a file, choose a quality level or a target size, and download a smaller version in seconds.
Behind the scenes, the compressor uses your browser's own Canvas engine to re-encode the image, the same technology used by professional photo tools. For JPG and WebP you control the balance between file size and sharpness with a quality slider; PNG stays lossless, so use the target-size option if you need a PNG that's guaranteed to fit a specific limit.
Because nothing is uploaded, compression starts the instant you drop a file in, and it works just as well on a slow mobile connection as it does on fiber — there's no queue and no file waiting on a server somewhere.
