It has always been possible to shorten long Microsoft Forms URLS with third-party services like Bitly and Yellkey. Recently, Microsoft added a built-in URL shortener to Microsoft Forms. This option now appears when you click on the share button in Microsoft Forms. Check the small box that reads “shorten URL” and you’ll have a shortened URL to share.
While the shortened URLs that Microsoft Forms provides are shorter than the default URLs for Forms, they’re still fairly long URLs that aren’t exactly memorable. To create shortened URLs that people can actually remember and spell you’ll want to use the custom URL shortening provided by services like Bitly, TinyURL, or Yellkey. All three of those URL shortening services are demonstrated in this short video.
