Frequently asked questions

What is the difference between camelCase and PascalCase?

camelCase starts lowercase (myVariableName), PascalCase starts uppercase (MyVariableName). Both strip spaces and underscores from the words.

Does Title Case keep small words lowercase?

Yes. Articles and short prepositions (a, the, of, in…) stay lowercase unless they are the first or last word, following common editorial style.

Is my text uploaded anywhere?

No. The conversion happens locally in your browser with JavaScript — nothing is sent to any server.
