Leetspeak has been a staple of internet culture since the early BBS days — this tool converts any text into it instantly, with two intensity levels.
What Is the Leetspeak Converter?
It substitutes common letters with lookalike digits — a→4, e→3, i→1, o→0, s→5, t→7 at “Basic” intensity, plus b→8, g→9, l→1, z→2 at “Full” intensity — while leaving punctuation, numbers, and spacing untouched.
How to Use It
- Open the tool at /tools/leetspeak-converter.
- Type or paste your text.
- Choose Basic or Full intensity.
- Copy the converted leetspeak output.
Key Features
