AI upscaling, explained simply
Normal resizing just stretches pixels, which looks blurry. AI upscaling guesses the missing detail instead.
The AI learned what sharp edges, faces and textures look like. It paints in plausible detail.
This matters when you have an old photo, a low quality clip or a small logo you want to print or show larger.
The new detail is a guess. It can look nice, but it may add things that were not in the original.
