Leetspeak (also written l33t or 1337) is an internet writing style that replaces letters with visually similar numbers and symbols. It started in early bulletin-board and gaming communities and is still used for usernames, gamertags, memes, and playful obfuscation. This Level 2 converter goes beyond the simple vowel-to-digit swaps of Level 1 by mapping more letters to symbols, producing a denser look.
How it works
Each character is checked against a substitution table. Lowercase and uppercase versions of a letter map to the same replacement. The Level 2 table includes mappings such as A -> @, B -> 8, E -> 3, G -> 6, I -> 1, L -> |, O -> 0, S -> 5, T -> 7 and Z -> 2. Any character without a mapping — including spaces, digits already present, and punctuation — is left untouched, so the overall shape of the text stays readable.
Tips and notes
Leetspeak is a stylistic effect, not encryption. Several letters can collapse onto the same symbol, so the transformation is one-way and should never be relied on to hide sensitive information. For an even more extreme look with multi-character substitutions like M -> /\/\, try the Level 3 converter.
