URL Shortener Tool
Generate short URL codes using Base62 encoding, create QR codes for any URL, and understand how URL shortening works.
How Base62 URL Shortening Works
The long URL is processed through a hash function to produce a numeric value. This ensures the same URL always generates the same short code.
The hash is converted to Base62 (0-9, A-Z, a-z) producing a short, URL-safe string. 7 characters can represent 62^7 = 3.5 trillion unique codes.
The mapping (short code to original URL) is stored in a database. When visited, the server looks up the code and redirects (301/302) to the original URL.
How URL Shortening Works
URL shorteners work by creating a unique short code for each long URL and storing the mapping in a database. When someone visits the short URL, the server looks up the original URL and redirects the visitor. This tool demonstrates the encoding process using Base62 (0-9, A-Z, a-z) which generates compact, URL-safe codes.
