TLDR

Showcase your brand in the browser tabs with the following:

<!-- Spice up your tab with your logo --> <link rel="icon" href="your-logo.png" type="image/png">

Swap "your-logo.png" with the path to your logo. Remember, most browsers are friends with PNG—it's crisp and clear.

Picking the right favicon size and format

A favicon isn't a full-size portrait—it's a stamp. Stick with 32x32 or 16x16 pixels to avoid an accidental browser freeze.

The modern browsers are all good friends and get along well with .ico, .png, and .gif formats.

<!-- The spirit of Warhol would totally approve of your tiny art piece saying yes --> <link rel="icon" href="/favicon.png" type="image/png">

Pick the file format that best matches your logo's background—a transparent PNG works with just about any tab color!

Creating and placing the favicon

Favicon.cc and RealFaviconGenerator are your trusty tools for creating perfect favicons—no arts degree required!

But where does the favicon file live? Some folks leave it in their website's root directory—an easy find for the browser. However, feel free to specify another spot using the <link> tag:

<!-- Like a treasure map leading to your image --> <link rel="icon" href="path/where-you-buried/favicon.png" sizes="32x32" type="image/png">

Verifying the favicon: A/B testing

Don't forget to check your hard work—see if your favicon displays as expected by navigating to www.yourwebsite.com/favicon.ico. Looks good? Awesome!

Remember also to run compatibility tests. Your favicon must wave to visitors on different browsers and shout 'hello' on mobile screens too.

Sneaky tricks and caveats

Background matters

Your favicon needs a tasteful outfit, not garish attire. Opt for a transparent background to maintain its versatility across different browser UIs.

Favicon fashion

Favicons are fashion victims too! They stick to browser memory, refusing to leave even when you want to change them. To introduce the new iteration, use some cache-busting trickery:

<!-- The fashion police bringing the new season --> <link rel="icon" href="path/to/favicon.png?v=2">

The SVG revolution

SVG favicons are the new kids on the block, offering mega flexibility with size scaling and even animation. Keep an eye out, ground-breaking changes are underway!

<!-- The birth of the SVG revolution --> <link rel="icon" href="path/to/favicon.svg" type="image/svg+xml">

The Mighty 'type'

Specify the expected file by using the type attribute in your <link> tag. Help your browser sneak a peek in advance to improve loading times:

<!-- Give your browser the 'heads up' and watch the speed! --> <link rel="icon" href="path/to/favicon.ico" type="image/x-icon">
