Base62 Encoding: 1 common technique is to use Base62 encoding (which works by using 62 people: 0-9, A-Z, plus a-z) on an integer ID. The ID corresponds into the entry inside the database. This process makes sure that the small URL is as short as feasible.
Random String Era: An additional strategy is to produce a random string of a fixed size (e.g., six people) and check if it’s by now in use during the database. If not, it’s assigned to your extended URL.
