FAQ

What is a case converter used for?

A case converter changes the capitalization style of your text without you having to retype it. Writers and marketers use it to fix all-caps pasted content, build consistent Title Case headings, format meta tags, and create developer-friendly formats such as camelCase, snake_case and kebab-case in seconds.

How does Title Case handle small words?

This tool uses smart Title Case logic that capitalizes the main words while keeping short connector words like "a", "the", "of", "and" and "to" in lowercase, unless they are the first or last word of the line. That follows common editorial style guides and produces natural-looking, professional headlines.

Is my text sent to a server?

No. The entire conversion happens locally in your browser using client-side JavaScript, so nothing you paste is transmitted or stored anywhere. You can safely convert sensitive titles, drafts or client content, then copy or download the result directly from the page.
