How does in-browser super-resolution work?

It uses high-precision bicubic resampling combined with edge sharpening convolution kernels to increase pixel density without blurriness.

What is Pixel-Art mode?

Pixel-Art mode disables interpolation to maintain razor-sharp pixel edges for logos, retro game art, and pixel icons.
