Base62 Encoding: One particular popular solution is to use Base62 encoding (which takes advantage of sixty two characters: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds into the entry while in the databases. This method makes sure that the shorter URL is as shorter as you possibly can.
Random String Generation: Yet another strategy will be to generate a random string of a hard and fast size (e.g., six people) and Look at if it’s presently in use while in the database. Otherwise, it’s assigned to the long URL.
