Using a vector graphics editor, you can also export images to raster graphics like PNG at different resolutions. Therefore vector-based images can be scaled indefinitely without degrading. In Vector graphics, geometrical objects inclusive of points, lines, curves, circles or other shapes are used to form an image based on mathematical expressions. In Raster graphics, images are represented as arrays of pixels and thus they scale with loss of clarity. Images can be represented in two ways - Raster graphics and Vector graphics. Scaling up or down your app logo to fit different sizes may make it lose its clarity.

While submitting your app, you may need to include several versions of your app logo to support different sizes and screen resolutions.

Putting effort and time in designing app logo is important since a strong logo design results in an equally strong branding. Your app/product is identified by its logo. It shows up on many places like store, device home screen, lock screen, app tiles and in the app itself.
