Leetspeak Converter: The Ultimate Guide to 1337 Speak Translation

What Is Leetspeak?

Leetspeak (or 1337 speak, from "elite") is a writing system that replaces standard letters with visually similar numbers and symbols. It originated in the 1980s on Bulletin Board Systems (BBS) and early internet forums as a way to demonstrate technical knowledge and bypass text filters.
