A beautiful and elegant background can elevate the overall look of an app. Using a blurred image as background helps users in keeping focus on the content and at the same time, it gives your app a beautiful look.

In order to save your time and efforts, we have handpicked some of the best free sets of high quality blurred background images that you can use in your apps.
