FAQ

Is my text sent anywhere?

No. The conversion happens entirely in your browser. Your text is never uploaded to a server, so it works offline and stays private.

Which cases are supported?

UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE — covering everyday writing and common programming styles.

What’s the difference between camelCase and snake_case?

They’re ways to join multiple words without spaces. camelCase capitalises each word after the first (myVariableName); snake_case lowercases everything and joins with underscores (my_variable_name). Both are popular in code.
