Frequently asked questions
- What's the difference between Title Case and Sentence case?
- Title Case capitalises the first letter of every word — the style used for headlines and titles. Sentence case only capitalises the first letter of each sentence, the way normal prose is written.
- Is my text saved anywhere?
- No. Switching case is just string manipulation, and your browser can do that instantly on its own — there's no reason for this tool to ever send your text anywhere.
- Does camelCase or snake_case strip punctuation?
- Yes — both are built for identifiers, so anything that isn't a letter, number or space is removed before the words are joined.
