icongen - Web and App icons and PNG favicons

icongen@github.

Icons to generate

Image (SVG preferred) and target path

Example HTML <head> to use icons

Use the given source SVG as favicon.svg. Add favicon.ico to website root but do not add to HTML 

<link rel="icon" href="/iconx/favicon.svg" type="image/svg+xml">
<link rel="apple-touch-icon" href="/iconx/apple-touch-icon.png"/>
<link rel="manifest" href="/iconx/manifest.json" />

SVG with dark mode option example

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100">
  <style>
    @media (prefers-color-scheme: dark) {
      .icon { fill: #fff } 
    }
  </style>
  <path class="icon" fill="#000" … />
</svg>
