How does the image upscaler increase resolution without losing quality?

The engine uses bicubic interpolation combined with Contrast-Adaptive Sharpening (CAS) and high-pass convolution kernels. This reconstructs edge gradients, sharpens blurred contours, and removes compression noise without muddying textures.

What upscaling factors are available?

You can upscale images by 2x (200% resolution boost) or 4x (400% resolution boost), up to ultra-high-definition 4K prints.

How does the interactive Before/After comparison slider work?

After enhancement, an interactive vertical divider appears across your image. Drag the divider left and right to inspect the sharp enhanced clarity directly against your original unedited photo in real time.

Are my images processed privately?

Yes. All image tensor math and canvas sharpening algorithms execute locally on your device CPU/GPU. Your personal or client photos are never uploaded to any cloud server.
