What is leetspeak?
Leetspeak (“1337”, from “elite”) is an internet slang that swaps letters for visually similar numbers and symbols — A becomes 4, E becomes 3, O becomes 0. It started in early bulletin-board and gaming culture. The basic level uses the most common substitutions for readable text, while advanced swaps more letters for a denser, hacker-style look. Conversion runs entirely in your browser.
