Case Converter
Fix any text's capitalization in one click. Switch between UPPERCASE, lowercase, Title Case, Sentence case and developer favorites like camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE.
How it works
Simple text transforms run locally: direct case mapping for upper/lower/title/sentence styles, and word splitting (on spaces, punctuation and camelCase boundaries) for the programming cases, which rejoin words with the right separators and capitalization.
Frequently asked questions
How does Title Case work?
Every word's first letter is capitalized and the rest lowercased. It capitalizes all words — it doesn't apply style-guide exceptions for small words like 'and' or 'the'.
Can it convert camelCase to snake_case?
Yes. The word splitter detects camelCase/PascalCase boundaries, so myVariableName becomes my_variable_name in one click.
Is my text sent anywhere?
No — everything is transformed in your browser. Nothing is uploaded or stored.
