Base62 Encoding: One frequent method is to employ Base62 encoding (which uses 62 people: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds to the entry within the database. This technique makes sure that the short URL is as limited as possible.
Random String Technology: A different approach would be to create a random string of a fixed duration (e.g., six people) and Look at if it’s already in use in the databases. If not, it’s assigned to your very long URL.
