Don't buy it. I purchased it and am trying to get a refund. They said it allows for large file processing but it still cuts the image size in half if you do it offline. If you process it online thru the desktop version it cut my file size from 13mb to 600 kb and you need to use a credit to process online even though you purchased the desktop version. Also if you use the desktop offline version the Background remover, photo restore and portrait transform are not available.
