How it works
Check your image width
Divide 3840 by your image’s width: 1920 px needs 2×, 960 px needs 4×, 480 px needs 8×.
Upload with the right factor
“Upscale 4×” is preselected. Change it to 2× or 8× in the Method list if your image is larger or smaller.
Download in 4K
Save the enlarged image for your 4K monitor, TV or print.
Getting an image to 4K
A 4K screen has four times as many pixels as Full HD. Stretching a small image in an editor just makes it blurry; an AI upscaler adds plausible detail so edges stay clean.
Use it for wallpapers, old digital photos and artwork you want to show full-screen on a 4K display.
