W3Schools Favicon Tutorial: What It Covers and How It Applies to SVG Logo Files
An overview of the W3Schools favicon lesson: what a favicon is, the HTML link element it teaches, and what to check when your favicon starts as a vector logo.

The short answer
People who search for the W3Schools favicon lesson usually want a beginner reference on adding a small site icon to a web page with HTML. The tutorial covers the favicon, the small image that browsers show next to the page title in a tab, in bookmarks and in history lists. It also covers the link element in the page head that tells the browser where to find that image. The lesson is a coding reference. It does not teach logo design and does not supply any icon artwork.
Evidence gap: no confirmed details about the current version of the W3Schools page were available for this article. Its exact wording, examples, browser-support tables and last-update date are not verified here. The explanations below follow general, widely documented HTML practice rather than a quotation of the tutorial.
What the lesson teaches: the HTML link element
Adding a favicon in HTML comes down to one line inside the head section of the page. The rel attribute declares the file as an icon, the type attribute states its format, and the href attribute points to the file. A typical pattern looks like this:
<head>
<title>My Page</title>
<link rel="icon" type="image/x-icon" href="favicon.ico">
</head>Beginner tutorials like this one usually advise saving the icon file in the site's folder structure, then referencing it with this element. Many sites also place a file named favicon.ico in the site's root folder, because many browsers look for that file there even without a link element.
How a tutorial differs from a favicon design workflow
An HTML lesson explains how to reference an icon. It does not cover how to turn a logo into an icon that still reads clearly at very small sizes. Those are separate tasks. If you are starting from a vector logo, the HTML step is usually the simplest part. The design and file preparation take more effort.
- Simplify the mark: full logos with wordmarks, thin strokes or fine detail tend to blur at tab size, so favicons often use only a symbol, monogram or single letter from the logo.
- Check contrast: the icon may appear on light and dark browser themes, so test it against both.
- Choose formats deliberately: decide whether you need a scalable vector icon, raster fallbacks, or both.
- Test in real browsers: rendering differs between browsers and operating systems, so preview the actual result instead of relying on the source artwork.
SVG, ICO and PNG favicons: vector versus raster
The format you link to affects how the icon scales. An SVG favicon can hold vector artwork that stays sharp at any size. ICO and PNG files are raster images made of pixels, although an ICO file can bundle several pixel sizes in one file. An SVG favicon uses the same link element with a different type value:
<link rel="icon" type="image/svg+xml" href="favicon.svg">
<link rel="icon" type="image/png" href="favicon.png">Browser support for SVG favicons is not uniform, so a common practice is to provide a raster fallback alongside the SVG version. Check current browser documentation for up-to-date support, because a tutorial's support table may lag behind browser releases.
| Format | Artwork type | Typical role |
| SVG | Vector (may also contain embedded raster images) | Scalable icon for browsers that support it |
| ICO | Raster, can hold multiple pixel sizes | Broad-compatibility fallback, often placed in the site root |
| PNG | Raster | Fixed-size icons and fallbacks |
Do not judge an SVG favicon by its extension alone
A file ending in .svg is not guaranteed to contain editable vector paths. An SVG can wrap an embedded bitmap, in which case it scales no better than a PNG and cannot be edited as shapes. Before you use an SVG logo as a favicon source, open it in a vector editor or inspect its markup. Confirm that it contains path or shape elements rather than a single embedded image. The same check applies to downloaded logo packs, where the preview image may be a raster rendering of the artwork.
Rights to the logo artwork
The HTML lesson only explains the code. It does not cover what you are allowed to put in the icon. Being able to download a logo file does not give you permission to crop, simplify or recolor it into a favicon, or to use its fonts or trademarked elements. If the logo is not your own, confirm the brand owner's usage terms before adapting it.
Bottom line
The W3Schools favicon material is useful as a quick reference for the link element and the basic idea of a site icon. To go from a vector logo to a working favicon, combine that HTML step with three checks: simplify the mark for small sizes, verify that the SVG really contains vector paths, and supply raster fallbacks where browser support for SVG falls short.
