4K Converter
Image to 4K keeps the original shape
The Image to 4K target brings the short edge to at least 2160 pixels. The image upscaler preserves the source aspect ratio, so a 16:9 landscape becomes 3840 × 2160 while portrait and square images keep their own shape.
For Image to 4K, if the source is already large enough, we keep its original dimensions instead of shrinking it.

Image to 4K cannot restore every detail
An image upscaler can make a source look clearer, but it cannot recover every face, letter, texture, or edge that is missing from the original.
Very small, blurry, noisy, or heavily compressed images leave less real information for Image to 4K. Always inspect the finished result at normal size and close range.
