What is a Favicon?

A favicon (short for "favorite icon") is a small icon that represents your website. It appears in browser tabs, bookmarks, address bars, and mobile home screens. Favicons help users quickly identify your site among multiple tabs and bookmarks.

Ensure your logo is visible and clear at 16×16 pixels
Avoid fine details that won't render well at small sizes
Test your favicon on both light and dark backgrounds
Use consistent branding across all favicon sizes
Save the .ico file as "favicon.ico" in your site's root folder
Consider creating different versions for dark mode if needed

ICO File Format

The ICO file format is a container that can store multiple image sizes in a single file. Modern browsers and operating systems will automatically select the appropriate size based on the display context. This makes .ico files ideal for favicons as they ensure your icon looks sharp across all devices and scenarios.
