Frequently Asked Questions

What is camelCase and when is it used?

camelCase means the first word is lowercase and each subsequent word starts with a capital letter — like "myVariableName". It is the standard naming convention in JavaScript, Java, Swift, and Dart.

What is the difference between snake_case and kebab-case?

Both separate words with a symbol and use all lowercase. snake_case uses an underscore (_) and is standard in Python and SQL. kebab-case uses a hyphen (-) and is used in CSS class names and URL slugs.

What is Title Case?

Title Case capitalises the first letter of every word — like "The Quick Brown Fox". It is the standard format for article titles, book titles, and headings in English.

Is my text kept private?

Yes. All case conversion happens in your browser using JavaScript. Your text is never sent to any server.

Can I convert large amounts of text?

Yes, there is no character or word limit. You can convert entire documents at once.
