Case Converter

Paste any text and convert it to uppercase, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case in a single click. The converter intelligently splits existing camelCase and PascalCase words at their boundaries, so developer-style identifiers are handled correctly alongside regular prose. All output is ready to copy instantly.
