Increasing an image's resolution while rebuilding detail, rather than just stretching pixels.
Upscaling is the process of increasing an image's resolution. AI upscaling goes beyond simple stretching by reconstructing edges, texture, and detail, so an enlarged image stays sharp instead of turning blurry.
It is essential when small or compressed source images need to work at larger sizes, such as print, banners, or high-resolution product pages. LUNA exports at up to 2K free, so images stay crisp where it counts.
Resizing stretches existing pixels and gets blurry. AI upscaling rebuilds detail, so the enlarged image stays sharp.
When a small or low-resolution image must be used at a larger size, like print or high-resolution web.
