Title Case Is Not One Thing
Editors argue about title case because the major style guides disagree. This tool uses the simple rule (capitalize every word); the guides are pickier:
- AP style - Capitalize words of 4+ letters, plus first and last words. "How to Beat a Brute-Force Attack"
- Chicago - Lowercase articles, prepositions and conjunctions regardless of length. "How to Beat a Brute-Force Attack" (same here, differs on "with", "from")
- APA - Like Chicago, but capitalize any word of 4+ letters, including prepositions.
For the web, the practical answer: pick one style and be consistent - Google doesn't rank capitalization, but readers notice inconsistency. Most modern product UIs (and this site) have switched to sentence case entirely.
A Quick Reference
| Style | Example | Typical use |
|---|---|---|
| Title Case | The Quick Brown Fox | Headlines, book titles |
| Sentence case | The quick brown fox | Body copy, UI labels |
| camelCase | theQuickBrownFox | JavaScript variables |
| PascalCase | TheQuickBrownFox | Class names |
| snake_case | the_quick_brown_fox | Python, databases |
| kebab-case | the-quick-brown-fox | URLs, CSS classes |
Why is this on a password site?
Habit, mostly - This tool shipped with the original PasswordGenerator.now and people kept using it. It pairs nicely with:
- The username generator - For formatting handles
- Base64 - For preparing strings before encoding
- The UUID generator - uppercase or lowercase IDs on demand
One security note: changing the case of a weak password does not make it strong. PASSWORD123 and password123 fall equally fast - See the strength checker, grab a truly random password, or learn what actually makes a password strong.
