AI upscaling

Increasing an image or video's resolution using models that infer plausible detail rather than simple interpolation.

Definition

AI upscalers reconstruct fine detail when enlarging media, improving sharpness for print or high-resolution display. They are built into many image generators and available as standalone tools, and video upscalers apply the same idea frame by frame. Results can invent detail, so faces and text need review.

Why it matters when choosing a tool

Upscaling makes generated or low-resolution assets usable for print and large screens without re-shooting or regenerating.
