Leetspeak Converter
Turn plain words into leetspeak, the 1337 style that swaps letters for the numbers and symbols that resemble them. Pick a basic mode that only touches the obvious letters, or a hardcore l33t mode that rewrites almost everything. Tap to copy and paste it into a gamertag, a bio or a message.
This leetspeak converter rewrites your text as 1337, the hacker-style code where an A becomes 4, an E becomes 3 and an O becomes 0. Basic mode keeps it readable by only swapping the letters that have an obvious number look-alike, while the hardcore l33t mode leans on symbols like #, |< and >< for a heavily scrambled result. Type your words and both versions update as you go. It is handy for a gaming handle, an old-school username, or just to write something the casual eye skips over.

Frequently asked questions
- What is leetspeak?
- Leetspeak, written 1337 or l33t, is an internet writing style from the early gaming and hacker scene where letters are replaced by numbers and symbols that look similar. E becomes 3, A becomes 4, T becomes 7, and so on. It started as a way to slip past word filters and signal you were in the know, and it stuck around as a playful aesthetic.
- What is the difference between basic and hardcore mode?
- Basic mode only swaps the letters with a clean number look-alike (a, e, i, o, s, t), so the word stays easy to read. Hardcore mode pushes further and rewrites nearly every letter with symbols, so m might become /\/\ and x becomes ><. Use basic when you still want it legible and hardcore when you want it heavily scrambled.
- Is leetspeak secure or encrypted?
- No. It is a simple letter-for-symbol substitution, so anyone familiar with it can read it back, and it offers no real security. Treat it as decoration or a light disguise, not as a way to protect anything private.
