Qzzr was built for all screens of all shapes (well, mostly squares and rectangles) and sizes, from the small smartphone in your pocket to the huge all-in-one sitting on your desk. That means putting a high-resolution image will ensure that your quiz's background looks great on every device.
When selecting a background image, you should use one that can be cropped to lots of different sizes and aspect ratios. Your quiz will typically appear on a large variety of devices and screen sizes. That means that we're going to have to crop your background for phones, tablets, laptops, desktops, and sometimes even TVs!
We recommend using a background image such as a landscape, a pattern, or something similar that can be cropped many different ways! Upload a picture with a 16:9 ratio. We'll crop the image when you upload it to 1440x900 px but then adjust how it appears each time it's displayed on a different device. You can either upload your own image, or use our Media Search tool.
