Base62 Encoding: A person typical technique is to use Base62 encoding (which makes use of 62 people: 0-nine, A-Z, in addition to a-z) on an integer ID. The ID corresponds towards the entry while in the database. This process makes sure that the brief URL is as shorter as feasible.
Random String Era: A further approach would be to make a random string of a fixed size (e.g., 6 characters) and Verify if it’s already in use in the databases. If not, it’s assigned to the long URL.
