If you have an application for which an existing version of the logo is unsuitable, please contact the development team.
Where possible, use the Scalable Vector Graphics (SVG) version for the best rendering. SVG is supported by almost all modern desktop and mobile browsers.
If using a PNG, please select one that is larger than your intended rendering size so it can be scaled down rather than up.
The image contains empty space around the edges which should be preserved.
