The ToolZone Image Resizer lets you set exact pixel dimensions, choose whether to preserve aspect ratio, and download the result immediately without uploading your file to a server. For profile photos that must be perfectly square, use the Image Cropper first and then resize to the correct dimensions.
Always start with a high-resolution source because resizing down produces better results than resizing up. Use PNG for images containing logos or text. After resizing, compress the result using the Image Compressor for faster uploads and better mobile performance.
