Why the Wallpapers Get Messed Up on Your iPhone
Depending on the screen size and the acceptable image resolution, the iOS installed on your iPhone automatically tries to best fit the selected photo on the background. In this attempt, it stretches the width and height of the image as needed.
If the image you have selected is not of the exact resolution specified for your iPhone's screen, iOS stretches it to put it on the full screen, thus making it pixelated/blurry.
As mentioned above, the best way to avoid such issues is to use the images that match the exact size for your iPhone.
However, since it is not possible with every image that you prefer to use as your iPhone's wallpaper, you must rely on a third-party tool that can do the job for you. A few such apps are listed below along with their details:
