Tips and common mistakes
- Use Sentence case for body text and most modern headings, and Title Case for formal titles.

- For strict headline rules such as AP or Chicago, use the Title Case Converter, which knows which small words to leave lowercase.
Frequently asked questions
What is the difference between Sentence case and Title Case?
Sentence case capitalizes only the first word and proper nouns. Title Case capitalizes the main words of a heading.
Will it break accented characters?
No. Letters such as é, ü and ñ are converted correctly.
Does it change my original text?
No. The original stays in the input box and the converted version appears separately.
