Frequently Asked Questions
Which case formats are supported?
The tool supports uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, and kebab-case.
Does the text leave my browser?
No. Conversion happens locally in your browser. Your text is not uploaded or stored.
Can I use it for code variable names?
Yes. camelCase, PascalCase, snake_case, and kebab-case are useful for variables, components, filenames, slugs, and CSS-style identifiers.
Does it preserve punctuation?
Plain uppercase, lowercase, and sentence case preserve most punctuation. Identifier formats normalize words and separators to match the selected naming style.
