About the Case Converter
Our free online case converter instantly transforms text between standard capitalization styles — like Sentence case, Title Case, UPPER CASE, and lower case — and coding case formats like camelCase, snake_case, kebab-case, and PascalCase. It's useful for formatting text in documentation and articles, or converting a variable or file name into the exact coding convention your project uses.
Every transformation runs entirely inside your browser using plain JavaScript string helpers — nothing is ever uploaded to a server, so your text stays completely private.

Yes. Uppercase and lowercase transformations work natively for standard international character sets, since they use the browser's built-in string case conversion.
Is my text uploaded anywhere?

Does it cost money?
No. The case converter is 100% free to use, with no registration or account required.
