Why it runs in your browser
Most file tools upload your document to a server, process it there and send it back. That means a stranger's machine holds your file, however briefly. This tool does the work locally using JavaScript, so nothing is transmitted. You can check: load the page, turn off your internet, and it still works.
Frequently asked questions
How does Title Case handle small words?
Words like 'and', 'of' and 'the' stay lowercase unless they begin the title, which follows the convention most style guides use for headlines.
Is my text sent anywhere?
No. The conversion is plain JavaScript running on your device, and nothing is stored or transmitted.
