Our AI enhancer increases resolution by 4x. For example, a 1080p image (1920 x 1080 pixels) will become 4K (3840 x 2160 pixels). Smaller images can still be enhanced, with the output being 4 times larger than your original.
Our AI technology enhances image quality during the upscaling process by analyzing and improving details. The final quality will depend on your original image – better input generally leads to better output.
