Yes. Most professional photo editing and management software has built-in functionality or an add-on for lens distortion correction. However it either requires having the original photo, or at least a non-cropped version with the exif data, or some knowledge of what body and lens and focal length was used. This utility doesn't require the original non-cropped area nor any other information about the picture that was taken. You could scrape a bunch of pictures from Instagram or Facebook and batch process away.
