What is text case conversion?

Text case conversion changes how letters are capitalized in text. Common formats include uppercase (ALL CAPS), lowercase (all small), title case (Each Word Capitalized), camelCase (forVariables), kebab-case (for-urls), and snake_case (for_code).

When should I use camelCase vs kebab-case?

Use camelCase for JavaScript variable names and function names. Use kebab-case for URL slugs, CSS class names, and file names. Use snake_case for Python variables and database column names.

Are these tools free to use?

Yes. All text case conversion tools are free, run in your browser, and require no account. Your text is never sent to our servers.

About Text Case Conversion

When and why to use different case formats.

When to use each case format

Uppercase and lowercase are familiar from everyday writing. Title case is used for headings and titles. In programming and web development, naming conventions matter: JavaScript uses camelCase for variables, CSS uses kebab-case for class names, and Python often uses snake_case. URL slugs work best in kebab-case.

Before generating a URL slug, you might use our Title Case Converter to format your heading, or the Slug Generator to create the final URL.
