Upscale · New
Upscale makes your photo 2K, 4K or 8K, or 2x, 3x or 4x bigger, and fills in the missing detail, so small pictures look crisp on TVs, wallpapers and prints.
Sizes are measured on the long side, so they work for portrait, landscape and square photos. The app shows the exact size your photo will get and greys out sizes it already has. Very small photos have a limit: 4K needs about 770 px on the long side, 8K about 1,540 px, and the app tells you the largest size yours can reach.
Each version runs on the same three photos, so you can compare them side by side. The examples zoom in on the same area of the photo so you can see the added detail. The examples use By factor. By size runs the same versions, then sets the exact size.
