title: Setting a favicon
type: text/vnd.tiddlywiki

"favicons" are small icons that most browsers display to help users identify websites. Note that all browsers support bitmap images, but only certain modern browsers support SVG format icons.

! favicons in the Browser

When TiddlyWiki starts up in the browser it looks for a tiddler called [[$:/favicon.ico]] and dynamically uses it as the favicon for the page. If you modify the image then the favicon changes instantly to reflect it.

<<.from-version "5.1.23">> To set an external image as the favicon, assign the URL to the ''_canonical_uri'' field of the [[$:/favicon.ico]] tiddler.

! favicons on the Server

On the server, the ServerCommand will serve the tiddler [[$:/favicon.ico]] at the path `/favicon.ico`.
