Frequently Asked Questions
Which case styles are supported?
Six styles: UPPERCASE (all caps), lowercase, Title Case (first letter of every word capitalized), camelCase, snake_case, and kebab-case. Each button transforms your text in place, so you can chain styles or edit the result before copying.
What is camelCase used for?
camelCase joins words without spaces, capitalizing every word except the first — like "myVariableName". It is the standard naming style for variables and functions in JavaScript, Java, and many other programming languages.
What is the difference between snake_case and kebab-case?
Both replace spaces with a separator: snake_case uses underscores ("my_variable_name"), commonly seen in Python and database column names, while kebab-case uses hyphens ("my-variable-name"), commonly used in URLs, CSS class names, and HTML attributes.
Is my text kept private?
Yes. Conversion happens entirely in your browser — your text is never uploaded, stored, or sent to any server.
