A little used feature, the ‘Minify URL’ option does just the same as other URL shorteners, it just does so right inside your chat.
To use it first click on ‘Minify URL’, next type in (or Paste) the URL you want to shorten, click Minify and the new link will be added to the input box right there and ready for you. It works in the Widget just the same.
If you’d rather use another URL shortener no problem! All valid links pasted into Mibbit can be resolved in the Extra Window or popped out to a new window for browsing.
