Why use a browser-based image tool?

Most online image tools upload your photos to a server. ImageTool.us works differently: your browser does the conversion, compression, resizing and cropping on your own device. That means no waiting in an upload queue, and no copy of your image sitting on someone else's server. Convert between JPG, PNG and WebP, compress photos before emailing them, resize images to exact pixel dimensions, and crop to common shapes — all free, with no watermark and no signup.
