Image compressor and converter
Choose one or more images, pick a format and quality, and download smaller copies. Everything runs in your browser. The files are never uploaded.
How it works
Each image is decoded by your browser, drawn onto a canvas at the chosen size, and re-encoded with the browser’s own encoder. JPEG and WebP use the quality setting; PNG is lossless, so quality does not change its size, but a size limit does. Transparent areas become white when saving as JPEG. Re-encoding removes camera metadata such as location tags, and an animated GIF becomes a single still frame. A converted file can occasionally come out larger than the original, usually when a small, already-optimized image is saved as PNG; the list marks those so you can keep the original. Format support depends on the browser: if a format is missing from the result, that browser cannot encode it, and the tool says so.
