About Text Case Converter - Camel, Snake, Pascal & Kebab Case

Text Case Converter is a free, browser-based tool that converts text into 12 case formats at once, including camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title Case, and more. It runs entirely in your browser, so your text never leaves your device.

It is built for developers and writers who need to switch a variable name, identifier, or heading between naming conventions without retyping it. As you type or paste, every format updates live and each result has its own copy button.

The converter splits your input on spaces, underscores, hyphens, dots, and camelCase boundaries, then rebuilds the words in the style you pick. It handles text line by line, so you can convert a whole list at once while keeping each line separate.

Processing is fully client-side with no network requests, and copying uses your browser clipboard. Results follow simple casing rules and do not understand acronyms or language-specific grammar, so review edge cases like initialisms before using the output.

Is my text sent to a server?: No. All conversion happens locally in your browser, and nothing is uploaded or stored on a server.
