You should be using SVG favicons. They’re supported in all modern browsers right now.
Also, you probably don’t need all these icon links and sizes you’re copying from projects to projects. Let’s find out what’s the absolute minimum required, word by word.
Icon
The main favicon can be an SVG of any size. The type type=”image/svg+xml”
is unnecessary.
<link rel="icon" href="favicon.svg">
Mask icon
For Safari, it’s a bit different. You need to add a mask-icon
. It’s also an SVG, but it has to be made of a single colour and placed on a transparent background. The browser adds the colour of the attribute.
<link rel=”mask-icon” href=”mask-icon.svg” color=”#000000">
Touch icon
The icon for iOS devices as well as favourites from browsers new tab page and more. You only need the 180 x 180
size, and the sizes
attribute is superfluous.
<link rel="apple-touch-icon" href="apple-touch-icon.png">
Manifest
The manifest.json
provides information about your web app or website. These lines are mandatory to pass Lighthouse
’s test. The icon linked is used by Android and Chrome. The largest size 512 x 512
is the only one needed.
{
"name": "Starter",
"short_name": "Starter",
"icons": [{
"src": "google-touch-icon.png",
"sizes": "512x512"
}],
"background_color": "#ffffff",
"theme_color": "#ffffff",
"display": "fullscreen"
}
The theme-color
meta
is still required for Android’s Chrome browser colour.
<meta name="theme-color" content="#ffffff">
Done
That’s it, that’s all the icons you need for the current modern browsers, everything else is unnecessary. The msapplication-TileImage
can be added if you want a different icon in Windows tiles otherwise the apple-touch-icon
is used. The TileColor
isn’t used anymore.
Everything else
Sadly, not everyone is on modern browsers yet BUT it can be easily resolved by dropping a 32 x 32
favicon.ico
at the root of your website. This works everywhere else, even at your grandma’s.
Dark mode
To finish, here’s a tip for dark mode. One of the benefits of an SVG favicon is that you can change the colour with CSS. Using the prefers-color-scheme
media
query, the colour of your favicon changes with the users dark or light mode. This method won’t work with the mask-icon
since the colour is in the attribute but Safari adds a white background if there isn’t enough contrast.
<svg xmlns="http://www.w3.org/2000/svg" width="16" height="16">
<style>
path {
fill: #000;
}
@media (prefers-color-scheme: dark) {
path {
fill: #fff;
}
}
</style>
<path fill-rule="evenodd" d="M0 0h16v16H0z"/>
</svg>
Result
Here’s the final result. Copy this in the <head>
of your website and don’t forget to place a favicon.ico
at the root. :v:
<meta name="theme-color" content="#ffffff"> <link rel="icon" href="favicon.svg"> <link rel="mask-icon" href="mask-icon.svg" color="#000000"> <link rel="apple-touch-icon" href="apple-touch-icon.png"> <link rel="manifest" href="manifest.json">
