This tool instantly reformats any text into the capitalization style you need. Use it to clean up sentence case for writing, apply proper Title Case to headlines, or turn phrases into snake_case or kebab-case for code identifiers and slugs. Everything runs locally in your browser, so nothing you type is ever sent to a server.
How to use
- Type or paste the text you want to convert into the input box.
- Pick a conversion mode: Sentence case, Title Case, snake_case, or kebab-case.
- Toggle the mode-specific option if needed, such as forcing lowercase elsewhere or capitalizing every word.
- Check the result box and click the copy button to grab the converted text.
FAQ
- How does Title Case handle small words like 'the' or 'of'?
- By default, minor words such as a, the, and, of, and in stay lowercase unless they're the first word. Enabling the 'capitalize every word' option removes that exception.
- Does it work with non-English text?
- Sentence case and Title Case also recognize Korean characters for capitalization after punctuation. snake_case and kebab-case split any Latin letters, digits, or Korean characters into word tokens.
- Is my text uploaded anywhere?
- No. Conversion happens entirely in your browser, and the text is never sent to or stored on a server.
