This PNG (Portable Graphics Network) format image will give the best quality, and has the benefit of a transparent background. This is the preferred image to use.
This JPEG (Joint Photographic Expert Group) version is of reduced quality, which is the nature of JPEGs, but is only slightly smaller in file size to that of the PNG. JPEGs do not support transparency.
This GIF (Graphics Interchange Format) version provides a small file size and a transparent background, but is mainly suitable for web use.
