Case Converter changes text between upper case, lower case, title case and sentence case, and turns phrases into code-style names. Type or paste once and all nine results appear together: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE, each with its own Copy button. Existing identifiers such as helloWorld, hello_world or hello-world are split into words first, so you can switch between naming styles directly. Character, word and line counts update as you type, and your text never leaves the browser.

Both join words without spaces and capitalise each word, but camelCase starts with a lower-case letter (helloWorld) while PascalCase starts with a capital (HelloWorld).
No. Title Case capitalises the first letter of every word, so check short words if you follow a style guide that keeps them lower case.
Yes. Paste the identifier and the snake_case, kebab-case and CONSTANT_CASE results split it at each capital letter, hyphen or underscore.
UPPERCASE, lowercase, Title Case and Sentence case keep your line breaks. The code-style cases join all the words into a single name.
