How this title case calculator works

  1. We normalize whitespace and detect each word while preserving punctuation and emoji.
  2. Rules for AP, Chicago, or the smart preset determine which words stay lowercase.
  3. Acronym detection keeps all-caps words untouched when enabled.
  4. You can copy the finished output or save it to the recent conversions list.

Helpful reminders

  • Double-check brand names or legal entities that intentionally break casing rules.

Frequently Asked Questions

How do headline guides differ?
Chicago capitalizes words longer than three letters, AP keeps short conjunctions/lowercased, and smart title case uses a general best-practice list.

Yes. Add custom exceptions and we’ll keep them lowercase except when they appear as the first word.
