Case Converter

A case converter is a tool that transforms text between different capitalization formats. Common conversions include changing text to uppercase, lowercase, title case, sentence case, and programming conventions like camelCase and snake_case.

camelCase is used in programming for naming variables and functions in languages like JavaScript, TypeScript, and Java. For example, userFirstName and calculateTotalPrice. It's the standard naming convention in many codebases.

Title case capitalizes the first letter of every major word — The Quick Brown Fox. Sentence case only capitalizes the first word — The quick brown fox. Title case is commonly used for headlines and book titles, while sentence case is used for normal text.

Yes. All conversion happens locally in your browser. Your text is never sent to any server, making it completely private and secure.

snake_case is used in Python and Ruby for variable names and function names. It's also commonly used for file names and database column names. Example: user_profile_image.
