Frequently Asked Questions

What is title case?▾

Title case capitalizes the first letter of each major word while keeping minor words (a, an, the, of, in, etc.) lowercase, unless they are the first or last word. Example: "The Quick Brown Fox Jumps Over the Lazy Dog."

What is the difference between camelCase and PascalCase?▾

In camelCase, the first word starts lowercase and subsequent words are capitalized (e.g., myVariableName). In PascalCase, every word starts with an uppercase letter (e.g., MyVariableName). PascalCase is commonly used for class names.

Does the tool handle Unicode and accented characters?▾

Yes. The converter correctly handles accented characters, diacritics, and other Unicode text when changing case.

Is my text sent to a server?▾

No. All case conversion happens entirely in your browser using JavaScript. Your text stays on your device.
