Frequently asked questions
What’s the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, which is great for headlines. Sentence case only capitalizes the first letter of each sentence, like normal prose.
How do camelCase, snake_case, and kebab-case work?
These developer-friendly formats split your text into words and rejoin them without spaces — camelCase capitalizes every word except the first and joins them together, snake_case joins words with underscores, and kebab-case joins them with hyphens.
Can I convert the same text to a different case afterwards?
Yes. Your original text stays in the input box, so you can click a different case button at any time to re-convert it.
Is my text uploaded anywhere?
No. All case conversion happens locally in your browser with JavaScript — nothing is ever sent to a server.
