Frequently Asked Questions

How does AI upscaling work?▼

AI upscaling uses machine learning to intelligently add pixels when increasing resolution. Unlike basic resizing which creates blurry images, AI predicts what the higher-resolution version should look like.

What scale factors are available?▼

2x (doubles width and height) and 4x (quadruples resolution). A 500x500 image becomes 1000x1000 at 2x or 2000x2000 at 4x.

Will upscaling improve blurry photos?▼

AI upscaling can improve perceived sharpness of low-res images, but it cannot recover detail that wasn't captured. It works best with images that are small but clear.
