Contributing

This repository welcomes contributions and corrections. Before submitting a pull request, ensure that you respect these guidelines for SVGs:

  • Include the SVG namespace declaration xmlns="http://www.w3.org/2000/svg". This is not required if the SVG is included inline on HTML5 web pages.
  • Include a descriptive <title> element for accessibility. The <title> must have an ID of the format simpleicon-<iconname>-title - for example, <title id="simpleicons-github-title">GitHub icon</title>.
  • Add aria-labelledby="simpleicon-<iconname>-title" and role="img" to the <svg> element to improve screen reader support.
  • Use a viewBox of 24 by 24, following Google’s Material Design guidelines for system icons.
  • Ensure the icon is scaled to fit the viewbox, while preserving the icon's original propportions. This means the icon should be touching at least two sides of the viewbox.
  • Ensure the icon is horizontally and vertically centered.
  • Ensure that all paths and strokes have been converted to fills.
  • Ensure your SVG is monochromatic. Remove all fill colors so that icons default to black.
  • Minify your SVG after exporting it. We recommend using SVGO or SVGOMG to automate this process. Do not go below a precision of 3.

JSON data for simpleicons.org

In addition to following the guidelines for SVGs, list new icons in the _data/simple-icons.json file. Each icon in the array has three required values:

  • The title of the new SVG.
  • A hex color value that matches the brand or logo's main accent color. (Without the # pound symbol.)
  • The source URL of the logo being used.

Here is the object for the GitHub logo as an example:

{
  "title": "GitHub",
  "hex": "181717",
  "source": "https://github.com/logos"
},

SVG example

Before minification, your SVG should look follow the template below:

<svg aria-labelledby="title" role="img" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
  <title>[BRAND] icon</title>
  <path [VALUE] />
</svg>

While the parent <svg> element can sometimes contain other attributes, the attributes listed above are the only necessary ones. You can safely remove attributes like width and height, or clean them using a tool like SVGO or SVGOMG.

Here is the un-minified contents of the GitHub icon, for reference:

<svg aria-labelledby="title" role="img" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg" fill-rule="evenodd" clip-rule="evenodd" stroke-linejoin="round" stroke-miterlimit="1.414">
