What does upscaling an image involve?
Upscaling an image means increasing its number of pixels so you can print it larger or display it on high-resolution screens. The challenge is to do it without visible pixels or jagged edges.
Our tool uses high-quality interpolation followed by an “unsharp mask” filter that restores a sense of sharpness at the edges. It does not invent detail like artificial-intelligence systems, but it delivers a clean, natural result without uploading your photos to any server.
