Base62 Encoding: One widespread method is to implement Base62 encoding (which utilizes sixty two characters: 0-9, A-Z, and a-z) on an integer ID. The ID corresponds on the entry in the database. This process makes certain that the small URL is as brief as is possible.
Random String Era: Yet another technique should be to deliver a random string of a fixed length (e.g., 6 characters) and Look at if it’s already in use while in the databases. Otherwise, it’s assigned towards the prolonged URL.
