It's easy to create a tiny url from a long website url for
security and short typing time.You can short many url's of
popular websites like amazon.com,ebay.com,etc.For example
following websites allow you to short your url's, you need to copy and paste the url only to make shorter url -
If you are using mozilla firefox browser there are many
tinyurl and other add-ons available to add that feature
in your browser.Chrome also has this feature.
Hope that helps!
