Upscaling
Enlarging an image to higher resolution while restoring or inventing detail.
AI upscalers (ESRGAN, SwinIR, 4x-UltraSharp, Topaz Gigapixel) take a 1024px image and produce a 4K or 8K result with believable extra detail — not just blurry interpolation. Synexa renders up to 2K and does not upscale beyond that.
