camelCase writes compound words with no spaces, starting with a lowercase letter, and capitalizing the first letter of each subsequent word. Example: "my variable name" → "myVariableName". Used widely in JavaScript and Java.

What is the difference between snake_case and kebab-case?

snake_case uses underscores to separate words (e.g., my_variable_name) and is common in Python. kebab-case uses hyphens (e.g., my-variable-name) and is used in CSS class names and URLs.

Title Case capitalizes the first letter of every major word. Minor words like "a", "the", "and", "of" are kept lowercase unless they start the title. Example: "the quick brown fox" → "The Quick Brown Fox".

Can I convert a whole document?

Yes, you can paste an entire document. The tool handles large texts with thousands of words without any slowdown.

PascalCase (also called UpperCamelCase) capitalizes the first letter of every word. Example: "my class name" → "MyClassName". Commonly used for class names in Java, C#, and TypeScript.
