Text Case Converter

The Text Case Converter reformats any text into eight capitalisation styles: UPPERCASE, lowercase, Title Case, Sentence case, tOGGLE cASE, camelCase, snake_case, and kebab-case. It fixes SHOUTING TYPOS, rescues documents typed with caps lock on, and formats identifiers for code and URLs without retyping.

Each style has a natural habitat. Title Case capitalises principal words and suits headings, book titles, and email subjects. Sentence case mirrors normal prose and is the standard for most modern UI text. Toggle case inverts each letter to reverse an accidental caps-lock paragraph. The code styles matter for developers: camelCase for JavaScript variables, snake_case for Python and database columns, kebab-case for URLs, CSS classes, and file names. The converter strips spaces when producing camelCase, snake_case, or kebab-case output, turning quarterly report into quarterlyReport, quarterly_report, or quarterly-report.

Paste the text, choose the target style, and copy the result. Multi-line input keeps its line breaks in every style except the code formats, which collapse whitespace first.

Text is transformed entirely in your browser - nothing you paste is transmitted anywhere, which makes the tool safe for confidential documents.
