Recommended HTML head icon tags
Over the years, I've seen many different and often conflicting guidelines about favicons and which tags are essential. Nowadays, I think you can get away with a very minimal set of meta tags and tailor them to your needs as you go. Here's my recommendation for the bare minimum you should include in your <head> element:
<head> <link rel="icon" sizes="192x192" href="favicon.png"> <link rel="apple-touch-icon" href="favicon.png"> <link rel="mask-icon" href="favicon.svg" color="#000000"> </head>
By creating a single 192x192 PNG asset, you can cover almost all modern devices and browsers, without too much hassle. If you want to go the extra mile, you can include a few more quite easily. Simply downscale the image and include more rel="icon" meta tags with different sizes attributes.
