Frequently Asked Questions
What is the difference between Title Case and Capitalized?
Both capitalize the first letter of each word. However, Title Case lowercases the rest of each word, while Capitalized preserves the original casing of the remaining letters.
Is my text stored on a server?
No. All conversion happens entirely in your browser using JavaScript. Your text never leaves your device.
Which case should I use for programming?
camelCase for JavaScript variables and functions, PascalCase for classes and components, snake_case for Python and database columns, CONSTANT_CASE for constants, and kebab-case for CSS class names and URL slugs.
