Frequently asked questions

What is Title Case versus Sentence case?

Title Case capitalizes the first letter of every word ("My First Post"). Sentence case capitalizes only the first letter of each sentence ("My first post"). This tool offers both.

Does Title Case skip small words?

This converter capitalizes the first letter of every word for predictability. Style guides differ on whether to lowercase articles like "the" and "of," so it leaves that editorial choice to you.

Is my text private?

Yes. Everything runs in your browser with JavaScript — nothing you type or paste is uploaded, logged, or sent to a server. You can disconnect from the internet after the page loads and it still works.

Do I need to sign up?

No. There is no account, no email, and no paywall. Open the page and use it.
