Simple Icons

Simple Icons is the de facto open-source source for company and brand logos on the web — 3,709 single-color SVG marks for software, services, social networks, and consumer brands. The collection is maintained by a large community of contributors and distributed under CC0 1.0, which dedicates the source code to the public domain (the brand marks themselves remain the property of their respective owners). Every logo is normalized to a 24×24 viewport with a single fill color, so the marks integrate cleanly with any palette and respond to currentColor in CSS. Simple Icons is the right pick for "log in with..." buttons, social-share rows, partner grids, footers, and credentials pages — anywhere you need recognizable brand marks without managing a sprawling collection of full-color logo files.
