What Is the Text Case Converter?

This tool instantly converts any text into UPPERCASE, lowercase, Title Case, or Sentence case — handy for headlines, titles, code labels, or cleaning up text pasted from elsewhere.

Formula

UPPERCASE and lowercase transform every letter. Title Case capitalizes the first letter of every word. Sentence case capitalizes only the first letter of each sentence.

How to Use This Calculator

Worked Example

Typing “the quick brown fox” and choosing Title Case produces “The Quick Brown Fox.”

Tips

Title Case here capitalizes every word, including short words like “the” or “of” — for editorial style guides that lowercase small words, adjust those manually.
