FAQ

What is leetspeak?

Leetspeak, or 1337, is an internet style that replaces letters with similar-looking numbers and symbols, such as E with 3 and A with 4.

What is the difference between basic and advanced?

Basic replaces the most common letters (a, e, i, o, s, t). Advanced swaps more letters, like b to 8 and g to 6, for a heavier leet look.

Can leetspeak be decoded back?

It is meant for style rather than secure encoding, but most leetspeak stays readable, so people can usually read it back at a glance.
