What is Leet Speak?
Leet speak (also called 1337 code) is a creative way of writing on the internet where normal letters are swapped for numbers and symbols that look like them. For example, replacing the letter E with 3 and T with 7 turns the word LEET into L337.
The name comes from the word elite. It was invented in the 1980s by early computer users and hackers to stand out in online forums. Over time, it became a massive part of online gaming culture, letting players create cool handles and send stylized messages in chat rooms.

Different modes change how heavily your text gets transformed. Here is a sample of how standard letters shift across styles:
| Letter | Basic | Advanced | Pro |
|---|---|---|---|
| A | 4 | @ | /-\ |
| E | 3 | 3 | € |
| H | |-| | # | (-) |
| I | 1 | ! | | |
| M | |\/| | /\/\ | [\/] |
| O | 0 | 0 | [] |
| S | 5 | $ | § |

How Text Decoding Works in this Tool
This tool converts normal English into leet speak and decodes leet back into plain text. Converting text to leet is straightforward, but turning leet back into English can be tricky.
Different online leet generators use completely different symbols for the same letters. If you paste text created by another tool, some characters might not match perfectly. We built our decoder to map the most common symbol variations so that even if a string comes from somewhere else, the decoded output stays clear enough to easily read.

- Translate old forum posts, gaming memes or encrypted messages back into normal English instantly.
