Upscaling a photograph to 4K is the process of enhancing its resolution to ultra-high-definition (UHD) – normally 3840 x 2160 pixels. Compared to basic resizing, which stretches images, AI resizing is based on machine learning to recover lost detail, refine edges, and deblur.

And the result is a naturally detailed, professionally enhanced image even when blown up 4x or more. The AI-powered upscalers maintain the texture, light, and realism. without any difficulty regardless of whether you are working on the portraits, product pictures, or artworks.

  • Sharper Edges: Ideal with landscapes, faces or products.
