Usage Guidelines

  • 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.

File Names

The Tar and Zip contain numerous files with various renderings of the logo, each named in one of these formats:

TYPE, COLOR, FILL and HEIGHT are described in the sections below.


  • logo - The crosshairs with surrounding perfSONAR text. Use this version to refer to perfSONAR the product.

  • powered - The standard logo with “powered” underneath. Use this version on hardware devices running perfSONAR or software that has perfSONAR embedded.

  • icon - The crosshairs only. Use this version as a symbol for perfSONAR nodes on network diagrams or as bullets in perfSONAR marketing material.


The color refers to the color of the crosshairs and text, if the latter is present. This will be black or white.


  • empty - The area inside the crosshairs is not filled.

  • full - The area inside the crosshairs is filled in the RGB color #31b63f at 100% opacity.

  • transparent - Like full, but with the opacity of the fill at 75%.


For PNG images, this is the height in pixels.
