FAQ

What is the difference between 1337 and Leet?โ–ผ
No difference. 1337 is the Leet spelling of Leet (L=1, E=3, E=3, T=7), both refer to the same language. Leet comes from the abbreviation of Elite.
What is the difference between Advanced and Basic styles?โ–ผ
Basic only replaces common letters (e.g., aโ†’4, eโ†’3), Advanced replaces all possible letters with multi-character combos (e.g., aโ†’@, wโ†’\/\/, mโ†’|\/|), lower readability but more "hacker".
Is reverse translation 100% accurate?โ–ผ
Not necessarily. Since Leet mappings have many-to-one relationships (e.g., 1 can be L or I), reverse translation may not be unique. The tool uses the most common mappings for decoding.
Does it support non-English text?โ–ผ
1337 Speak primarily targets English letter replacements. Non-English characters are preserved as-is. For best results, use English text.
