About this tool
Drop in an image, type the dimensions you want, and download the result. The aspect ratio lock keeps proportions intact by default so you don't accidentally squish anything. You can also pick the output format and tune the quality for JPG and WebP to balance file size vs. sharpness. All resizing happens on your device using the Canvas API, so nothing gets uploaded anywhere.
