Andrey Sitnik:
It is time to rethink how we cook a set of favicons for modern browsers and stop the icon generator madness. Currently, frontend developers have to deal with 20+ static PNG files just to display a tiny website logo in a browser tab or on a touchscreen.
Having only this in your markup will do nowadays:
<link rel="icon" href="/favicon.ico"><!-- 32×32 -->
<link rel="icon" href="/icon.svg" type="image/svg+xml" sizes="any">
<link rel="apple-touch-icon" href="/apple.png"><!-- 180×180 -->
<link rel="manifest" href="/manifest.webmanifest">Along with this in your linked manifest.webmanifest
{
"icons": [
{ "src": "/192.png", "type": "image/png", "sizes": "192x192" },
{ "src": "/512.png", "type": "image/png", "sizes": "512x512" }
]
}
