Leet Speak (1337) Translator

You want a distinctive gaming nick, a stylized bio, or you received a message full of 3s, 4s and 0s standing in for letters and want to read it. This translator goes both ways: it converts plain text to leet speak and turns leet back into text, updating as you type, with a copy button right next to the result.

Basic level swaps six letters for lookalike digits: a becomes 4, e becomes 3, i becomes 1, o becomes 0, s becomes 5 and t becomes 7. Advanced covers all 26 letters with symbols, like h turning into # and x into ><. The catch: advanced is not reversible, since i and l both become 1, and p and r both become |2. That is why Leet to Text mode only undoes the six basic digits; symbols are left as they are.

For a gaming nick, stick to basic: almost every game accepts letters and digits but rejects symbols like # and |_|. And do not count on leet to strengthen a password: swapping a for 4 is the first substitution every cracking tool tries. For styling posts and messages, anything goes. Conversion happens entirely in your browser; your text is never sent anywhere.
