Frequently asked questions

How does AI upscaling work?

AI upscaling uses deep learning models trained to predict what higher-resolution detail would look like. It adds realistic detail rather than just stretching pixels.

Is upscaled resolution the same as original high-resolution?

No. Upscaling adds estimated detail, not real captured data. The result looks sharper than a simple resize but cannot recover detail that was never in the original image.

What types of images benefit most from upscaling?

Portraits, product photos, and artwork with clear subjects. Very blurry or heavily compressed images may not improve significantly.

Does upscaling increase file size?

Yes. A 4x upscale produces an image with 16 times the pixel count, which results in a much larger file.
