A simple webpage I deployed on Heroku (currently inactive to conserve dyno hours) to shorten URL.
Go to zeph-urlshortener.herokuapp.com.
Type in the url you want to shorten in the Destination URL field. Type in the custom URL pattern you want the shortened URL to have in the Custom URL Pattern field. Once you have filled in both fields, click Shorten to generate the shortened URL. This is what you should see.
Congratulations, you have just shortened your URL! 🎉
(The URL looks long because I don't have a custom domain, but if you would like to donate to me so I can buy a custom domain, please feel free!)
