Common questions
What is the difference between title case and sentence case?
Title case splits on spaces, capitalizes the first letter of each word, and lowercases the rest. Sentence case lowercases the text, then capitalizes the start and any letter after a period, question mark, exclamation mark, or line break. A period inside an abbreviation is also treated as the end of a sentence.
Will Chinese characters change?
No. Chinese has no letter case, so those characters stay as they are. In mixed text, only the Latin letters are converted.
Is the text uploaded?
No. Conversion runs in your browser. No account is required, and the text is not sent anywhere.
