Case Converter
Convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case, and more.
Text case matters for readability, style guide compliance, and programming conventions, and manually retyping a sentence in a different case — or worse, trying to hand-fix camelCase into snake_case — wastes time on a purely mechanical transformation. Different contexts call for different conventions: headlines often use Title Case, JavaScript variables use camelCase, Python variables and database columns typically use snake_case, and URL slugs use kebab-case.
This tool converts your input text into eight common case styles simultaneously — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case — updating live as you type, with a one-click copy button next to each. Rather than guessing which transformation to apply and re-running it if it's wrong, you see every option at once and copy whichever matches what you need.
