AI Glossary / Upscaling

🎨 Image, video and audio

Upscaling is enlarging an image with AI help: instead of simply stretching pixels (which causes blur), the model "draws in" missing details based on how similar textures, edges, and faces typically look. A small graphic becomes a sharp high-resolution version. It's a standard final step when working with generators (which often create at lower resolution) and a lifesaver for old photos. Worth remembering that added details are guessed - an upscaler can "improve" a face so much it stops looking like the person.
