About Leetspeak Translator
Leet, written 1337, is a way of spelling with numbers and symbols that look like letters. It began on bulletin board systems (BBS) in the 1980s. There, "elite" status gave a user access to special files, games and chat rooms, and the word leet comes from elite.
This translator uses the most common one-to-one swaps, so the result stays readable. "elite hacker" becomes "31173 h4ck3r", and "leet" becomes 1337.
The letter chart
A → 4 B → 8 E → 3 G → 9 I → 1 L → 1 O → 0 S → 5 T → 7 Z → 2
Other letters stay as they are. Heavier leet styles use symbols too, like |-| for H or \/\/ for W. Those are hard to read, so this tool sticks to digits.
Leet words you will still see
1337 = leet n00b or n008 = noob, a beginner h4x0r = hacker p455w0rd = password w00t = a shout of joy pwned = beaten badly (from "owned")
In leet, 7 stands for T and 3 stands for E. So 1337 reads l-e-e-t.
Why decoding isn't perfect
Both I and L become 1, so the decoder has to guess. It picks i, which turns 1337 into "ieet" and h3110 into "heiio". Fix those by eye. Numbers that were real numbers in the original, like a year, will also turn into letters.
