A small library for manipulating the favicon

Tinycon allows the addition of alert bubbles and changing the favicon image. Tinycon gracefully falls back to a number in title approach for browsers that don't support canvas or dynamic favicons.

Alerts in the favicon allow users to pin a tab and easily see if their attention is needed.


Tinycon can take a range of options to customise the look

  • width: the width of the alert bubble
  • height: the height of the alert bubble
  • font: a css string to use for the fontface (recommended to leave this)
  • colour: the foreground font colour
  • background: the alert bubble background colour
  • fallback: should we fallback to a number in brackets for browsers that don't support canvas/dynamic favicons? Boolean, or use the string 'force' to ensure a title update even in supported browsers.
  • abbreviate: should tinycon shrink large numbers such as 1000 to an abbreviated version (1k). Boolean, defaults to true

Example usage


    width: 7,
    height: 9,
    font: '10px arial',
    colour: '#ffffff',
    background: '#549A2F',
    fallback: true
