Frequently asked questions
What does Title Case do?
It capitalizes the first letter of every word: “hello world” becomes “Hello World”.
When would I use Sentence case?
For normal prose — it lowercases everything, then capitalizes the first letter of each sentence.
Is there a character limit?
No. Convert as much text as you like, as often as you like.
Is my text stored anywhere?
No. Conversion runs entirely in your browser — nothing is uploaded.
