Convert anything into 1337‑speak — safely.
Make fun text, platform‑compliant usernames, or stronger passphrases. Everything runs locally in your browser.
1) Live 1337 Converter
Type text, flip options, copy out. Choose stricter modes for platform rules.
Tip: Toggle Strict to keep output username/password‑friendly.
2) Username Builder
Make compliant handles for different platforms. We keep it to safe characters and trim to max length.
Ready
Note: Presets are practical approximations. Always check platform rules in case they change.
3) Password Builder
Turn a phrase into a stronger, mixed‑set password — locally. We don’t store or send anything.
Reminder: Unique per‑site passwords are best. Consider a reputable password manager.
4) Site‑wide 1337 Toggle
Flip the entire page into 1337 — non‑destructive. We store the original text in memory and only change what you see.
We skip code blocks, inputs, and buttons. Refresh to restore if you ever get wild.
