Frequently asked questions
What is leet?
Leet, or 1337, is a way of writing that swaps letters for similar-looking numbers and symbols, born in online forums and games in the 1980s and 1990s. "Elite" becomes "3l173", for example.
What is the difference between the levels?
The basic level swaps only A, E, I, O, S and T for numbers. The intermediate level includes more letters. The advanced level uses symbol combinations for almost every letter, making it much harder to read.
Is it good for passwords?
Swapping letters for numbers in a known word barely increases security, because password-cracking programs already try those swaps. For passwords, use the random password generator.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 are free.
