High quality Images
All the photos undergo rigorous selection by quality and picture composition. Only the photos of Full HD resolution and above (4K wallpapers) are allowed. Also we select vivid and lively backgrounds that will look great after framing and setting on home desktop or lock screen. In case we get an photo copy of higher quality, we will substitute it for the new one. Our Images look great on AMOLED screen.

From time to time we exclude those images, which received poor rating and not interesting for our users. Thus, you get premium 4K backgrounds for free.

The system will select wallpaper resolution, suitable precisely for the screen of your phone or tablet. All the mobile devices are supported, including Ultra HD (UHD) resolution and Retina screens.
