Frequently Asked Questions
What is a text case converter?
A text case converter changes the capitalization style of any text. You can switch between UPPERCASE, lowercase, Title Case, camelCase, snake_case and kebab-case, which is useful for variable names, headlines and social media copy.
What is camelCase vs snake_case vs kebab-case?
camelCase joins words without spaces and capitalizes each word after the first (myVariableName). snake_case uses lowercase words joined by underscores (my_variable_name). kebab-case uses lowercase words joined by hyphens (my-variable-name).
Is the text case converter safe for sensitive text?
Yes. All conversion happens entirely in your browser. Your text is never sent to any server.
Does the converter handle mixed or already-converted input?
Yes. It splits text on spaces, punctuation and existing case boundaries (for example camelCase or snake_case input), so converting already-formatted text works reliably.
Is the text case converter free?
Yes, completely free with no registration, no usage limits and no uploads. Everything runs locally in your browser.
