How it works
Conversion runs entirely in the browser with JavaScript; no external API. Regex and string operations detect word boundaries and capitalization, then convert to snake, camel, pascal, kebab, title, etc. Input limited to 10,000 characters. File loading uses the FileReader API and is processed only on the client; nothing is sent to a server.
Privacy and data
Conversion happens in the browser; input is not sent to a server.
