Frequently asked questions
- How are word boundaries detected?
- Spaces, underscores, hyphens, and camelCase transitions are all treated as word boundaries.
- What's the difference between Title and Sentence case?
- Title case capitalizes every word; sentence case capitalizes only the first word of each sentence.
- Does it work with non-English text?
- Upper/lowercase use Unicode rules. Programmer cases (camel, snake, …) work best with Latin letters and numbers.
- Is my text uploaded?
- No. Conversion happens entirely in your browser.
