What is the difference between 4K, 1440p, and 1080p?
These refer to the number of horizontal pixels. 4K (3840×2160) is the sharpest, 1440p (2560×1440) is a popular high-res option, and 1080p (1920×1080) is standard HD. Choose the one matching your screen for the crispest result.
What are AMOLED wallpapers?
AMOLED wallpapers use true black backgrounds. On AMOLED/OLED phone screens, black pixels are turned off, saving battery and making colors pop.
Do I need to create an account?
No — you can browse and download wallpapers without an account. An account lets you save favorites, like wallpapers, comment, and submit your own wallpapers.
Can I submit my own wallpaper?
Yes! Create a verified account and visit the Submit page. Upload your image, add a title and description, and our team will review it before publishing.
How are "Related wallpapers" chosen?
We analyze the dominant colors of each wallpaper and match visually similar ones. This means related wallpapers share a similar mood and color palette, even if the subjects are different.
