Text Case Converter
Convert text to UPPER CASE, lower case, Title Case or Sentence case. Nothing you type leaves your browser.
How this is calculated
- UPPER CASE = every letter capitalised
- lower case = every letter lowercased
- Title Case = first letter of every word capitalised
- Sentence case = first letter after the start or after . ! ? … capitalised
Title Case here capitalises every word. Published style guides usually leave short words like “of” and “the” lowercase, so check the result before using it as a headline.
Sentence case treats any . ! ? as the end of a sentence, so text after an abbreviation like “Dr.” gets capitalised too.
Worked examples
- “hello world” → “HELLO WORLD” (UPPER CASE)
- “HELLO WORLD” → “hello world” (lower case)
- “the quick brown fox” → “The Quick Brown Fox” (Title Case)
- “don't stop believing” → “Don't Stop Believing” (Title Case)
- “hello world. goodbye world!” → “Hello world. Goodbye world!” (Sentence case)
