A favicon or “favorite icon” is an icon used when you bookmark a website. Web browsers use them in the URL bar to help identify a website visually.

Creating a Favicon:
A favicon can be created using GIMP. Resize the file to 16×16 and export it as a Window’s icon with an extension of .ico

To prepare the image to be saved as favicon.ico:
1. Make the image square.
2. Resize the image to 16 x 16 pixels.
3. Save the file as favicon.ico
4. Put it in the root directory of your website.

In WordPress:
Copy favicon.ico file into your current theme’s main directory.
If the theme has the option in the Settings for “Site Identity”, it must be added there.
