A Case Converter is a text transformation tool that changes the capitalization style of your text. Whether you accidentally left Caps Lock on, need to format a title for a blog post, or need to convert variable names for programming, this tool handles it all. It supports standard text formats like Uppercase, Lowercase, Sentence Case, and Title Case, as well as developer-specific formats like camelCase (javaScriptVariable), snake_case (python_variable), kebab-case (css-class-name), and PascalCase (ClassName).

Frequently Asked Questions
What is Title Case?
It capitalizes the big words but leaves small words like 'and', 'the', and 'of' lowercase. Perfect for headlines!
What is Sentence case?
It capitalizes only the very first letter of the sentence. Like normal writing.
Can I convert code variables?
Yes! I have special modes for camelCase, snake_case, and kebab-case just for programmers.
Is the conversion reversible?
Mostly yes, but if you convert to 'lowercase', you lose the original capitalization forever.
Does it handle accents?
Yes. 'é' becomes 'É' in uppercase. I handle all special characters correctly.
What is PascalCase?
It's like camelCase, but the first letter is Big too (e.g., 'MyClass'). Used a lot in C# and React.
What is Kebab Case?
It puts hyphens between words (e.g., 'my-cool-class'). It's standard for CSS and URLs.
