Frequently Asked Questions
- What's the difference between Title Case and Capitalized Case?
- Capitalized Case capitalizes the first letter of every word. Title Case follows style rules — it keeps short words like "a", "of" and "the" lowercase unless they start the title.
- Is my text uploaded anywhere?
- No. All conversions run locally in your browser; nothing is sent to a server.
