Frequently asked questions
What is leetspeak?+
Leetspeak (also written "1337" or "leet") is an alternative way of writing where letters are replaced by numbers and symbols that look similar — for example A becomes 4 and E becomes 3. It originated in early internet and hacker culture.
What is the difference between the modes?+
Light only swaps the most common letters (a, e, i, o, t…) so the text stays readable. Medium adds more replacements, and Hardcore uses multi-character symbol combinations for a heavily encoded look.
Is my text stored anywhere?+
No. The conversion runs entirely in your browser. Nothing you type is sent to a server or saved.
Can I convert leetspeak back to normal text?+
This tool focuses on converting plain text into leetspeak. Because several letters can map to the same symbol, an exact automatic reverse translation is not always possible.
