Favicons
A favicon (short for "favorite icon") is a small icon associated with a website, typically displayed in the browser's address bar, tab, bookmarks, and sometimes within the browsing history. Favicons help users quickly identify a website and provide a branded visual cue that enhances the user experience.
Characteristics of Favicons
Size and Format
- Size: The most common size for a favicon is 16x16 pixels, but modern websites often provide multiple sizes (e.g., 32x32, 48x48, 64x64) to support different devices and resolutions.
- Format: Favicons are usually in
.ico
,.png
, or.svg
format. The.ico
format is widely supported by all browsers, but.png
and.svg
formats are also popular due to their quality and scalability.
Location
- The favicon is typically placed in the root directory of a website (
/favicon.ico
). However, it can be located anywhere as long as it's correctly linked in the HTML document.

Adding a Favicon to an HTML Document
To add a favicon to your website, you need to include a <link>
element in the <head>
section of your HTML document. This element specifies the location and type of the favicon.
Basic Example (Using .ico
File)
<head>
<link rel="icon" href="/favicon.ico" type="image/x-icon">
</head>
Using a PNG File
<head>
<link rel="icon" href="/favicon.png" type="image/png">
</head>
Using Multiple Sizes for Different Devices
You can provide different sizes of the favicon for various devices by using multiple <link>
elements.
<head>
<link rel="icon" href="/favicon-16x16.png" sizes="16x16" type="image/png">
<link rel="icon" href="/favicon-32x32.png" sizes="32x32" type="image/png">
<link rel="icon" href="/favicon-48x48.png" sizes="48x48" type="image/png">
<link rel="icon" href="/favicon-64x64.png" sizes="64x64" type="image/png">
</head>
Creating a Favicon
Design the Favicon: Use graphic design software like Adobe Illustrator, Photoshop, or online tools like Favicon.io or RealFaviconGenerator.net to create your favicon. Ensure that it is clear and recognizable even at small sizes.
Convert to the Correct Format: If your favicon is in
.png
,.jpg
, or.svg
format, you might need to convert it to.ico
format. Many online tools can handle this conversion.Save and Upload: Save the favicon files to your website’s root directory or a designated folder and link them in your HTML document.
Best Practices
Use a Simple and Recognizable Design: Since favicons are small, they should be simple and easily identifiable. Avoid intricate designs or text that might become illegible at small sizes.
Provide Multiple Sizes: For better compatibility across devices, provide multiple sizes of your favicon. This ensures it looks good on high-resolution screens, mobile devices, and tablets.
Use the Correct Format: The
.ico
format is most widely supported, but.png
and.svg
offer better quality. Consider providing a favicon in multiple formats to cover all bases.Test Your Favicon: After adding the favicon to your website, test it across different browsers and devices to ensure it displays correctly.
