A favicon, or browser icon, is a small square image that displays next to a page's title in browser tabs and in other places across the web. Adding a custom favicon makes your site recognizable in a browser full of tabs or bookmarks.

All Squarespace sites start with our default cube favicon. If you leave it as-is, people who know the icon will recognize that you're part of the Squarespace community. You can replace it with your own image to better fit your site's brand.

Add a favicon

How you add a favicon depends on which version of Squarespace your site is on.

If your favicon doesn't update right away, we recommend clearing your browser cache and restarting your browser. Browsers can be very persistent in holding on to cached favicons.

Favicon display

Your favicon displays differently across browsers and devices: 

• In most cases, the favicon doesn't display on mobile browsers.
• Your favicon may display next to your site in mobile search results. 

Best practices

Image resolution

Favicon images work best across all browsers when sized between 100px × 100px and 300px × 300px, though they display at 16px × 16px. These are the standard favicon dimensions. While some browsers support larger favicon files, all will support that size.

File format

We recommend using an .ico or a .png file as the favicon image. Some versions of Internet Explorer may have trouble displaying a .png as a favicon.

File size

Favicon image files can't exceed 100 KB.

Multi-version favicons

We don't currently support multi-version favicons. To upload your favicon correctly, use a single version of the image and remove other versions from the file.
