Leet Speak Translator - 1337 - Online Leetspeak Decoder, Encoder (2024)

Leet (or 1337 or l33t5p34k) is a form of coded writing, in which letters are replaced by numbers or symbols graphically similar to common alphanumeric characters.

The term leet speak comes from the English elite speak which translates to language of the elite as opposed to those who do not understand the language, the neophytes (noobs).

The Leet Speak language consists of replacing the common characters (letters A-Z and sometimes digits 0-9) by others having a similar writing. The leet writing is therefore not unique and there are more or less complex variants for each character.

In its most basic version, the leet replaces at least the letter E by the number 3, the letter O by the number 0, the letters I and L by the number 1, the letter S by the number 5 and the letter T by the number 7.

Example: LEET therefore translates to 1337

In its advanced version, the leet offers character combinations for a single letter. Here is a 1337 leetspeak alphabet (not exhaustive)

Example: DCODE can be written in 1337 as:|) [ () |) [- or |> < <> |> €

The ciphered message has few alphabetic characters and lots of |_\[]031{} etc.

The number 1337 is a big clue, the presence of terms mixing letters and numbers like h4ck1ng (hacking) or g33k (geek) are clues.

Some call this language n00b 5p34k (noob speak).

Sometimes the message leet is not only modified, some vocabulary are used (usually from English terms):

Example: y00 => yoo => you

Example: teh => the

Example: pwn3d => owned
