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 upscales every paid render to 4K and offers 8K on Pro plans.
