Case Converter FAQ

What is the difference between Title Case and Sentence case?

Title Case capitalizes the main words of a phrase, while Sentence case capitalizes only the first word of each sentence.

What are camelCase and snake_case used for?

They are naming styles for programming. camelCase joins words with capitals, and snake_case joins them with underscores.

Does it work on long text?

Yes. You can paste anything from a single word to several paragraphs.
