One of the most comprehensive websites for Islamic wallpapers is IslamicDesktop.net. It offers a wide range of different wallpapers in a variety of resolutions suitable for smartphones, laptops and desktop computers.
Another good resource for Islamic wallpapers is HamariWeb.com, though there are fewer designs available as of 2015. Similar offerings can be found at IslamCan.com. A very large selection of images is available at MadaniWallpaper.com. BeautifulIslam.net offers wallpapers featuring verses from the Quran. Additionally, an app specifically designed for Android phones called Islamic Wallpapers is available on Google Play. This app allows users to save wallpapers directly to their phones and set them as background images.
