Frequently Asked Questions

What is the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (myVariableName) and is common for variables in JavaScript and Java. PascalCase capitalizes every word including the first (MyClassName) and is typically used for class and type names.

How does Title Case handle small words?

Title Case capitalizes the first letter of each word. For strict editorial styles (AP, Chicago) you may still want to lowercase short conjunctions and prepositions manually.

Is the Case Converter free?

Yes, the Case Converter is completely free with no usage limits. No signup, no account and no installation required.

Is my data safe?

Yes. All processing happens locally in your browser using JavaScript — nothing you type is uploaded or stored on our servers.
