WOW!! THIS ONE BROUGHT BACK A REALLY BLURRY OLD PHOTO AND MADE IT LOOK SO MUCH CLEARER!! I LOVE THAT IT RUNS LOCALLY TOO, SO I DON’T HAVE TO WORRY ABOUT UPLOADING PERSONAL PICTURES. IT CAN’T FIX EVERY WEIRD DETAIL, BUT FOR A FREE TOOL THIS IS REALLY IMPRESSIVE!!

Ann P Jun 4, 2023 v@ initial release

Very good job. File size concerns me, it was 10.2mb from a 1.63mb file. That was only one image, what if I had 50?
