Convert normal text into leetspeak, the classic 1337 5p34k where letters are swapped for lookalike numbers and symbols, and decode it back to plain English again. Leetspeak started in early internet and gaming culture as a playful, hard to read style, and it still turns up in usernames, passwords, memes and edgy captions. This tool maps common letters to their leet equivalents such as a to 4, e to 3, i to 1, o to 0, s to 5 and t to 7, and it can reverse the swap to translate leet back to readable text. Type in the box and the result updates instantly. Everything runs in your browser, so your text never leaves your device and the converted output is ready to copy.
