Case Converter FAQ
What is Title Case versus Sentence case?
Title Case capitalizes the first letter of every word, like a headline. Sentence case capitalizes only the first letter of each sentence, like normal writing.
What are camelCase, snake_case, and kebab-case?
These are naming styles used in code. camelCase joins words with capitals (myVariableName), snake_case joins them with underscores (my_variable_name), and kebab-case joins them with hyphens (my-variable-name).
Can I convert text I copied from a document?
Yes. Paste text from any source, then pick a case. This is handy for fixing text that came in all caps or in the wrong format.
Is my text private?
Yes. All conversion happens in your browser on your own device. Your text is never sent to any server.
Do I need to sign up?
No. The case converter is free with no account and no limits.
