FAQ
Common questions
Is my text really private?
Yes. The page is plain HTML, CSS and JavaScript. Your text is processed by JavaScript running on your own device and is never transmitted, stored or logged. You can verify this in your browser's network tab — no requests are made while you type or convert. See our Privacy Policy.
What's the difference between Title Case and Capitalized Case?
Capitalized Case capitalizes Every Single Word. Title Case follows editorial (AP-style) rules: minor words such as “a”, “of”, “the” and “to” stay lowercase unless they are the first or last word of the title.
How do the developer cases handle word boundaries?
The tokenizer splits on spaces, punctuation, hyphens, underscores and camelCase boundaries — so getHTTPResponse converts cleanly to get_http_response. Multi-line input is converted line by line, so pasted lists keep their structure.
Is there a maximum text length?
No hard limit. Because everything runs locally, the practical limit is your browser's memory — essays, articles and long code files are no problem.
Can I use this for commercial work?
Yes, freely. Converted text is yours; we claim no rights over anything you type or convert. See the Terms of Use.
