This image compressor resizes and re-encodes your photos to JPEG or WebP with a quality slider, to shrink a file before emailing it, publishing it on the web or sharing it. You see the final size before downloading.
Processing happens entirely through the browser canvas: your images never leave your device, no upload, no tracking and no ads.
