Frequently asked questions

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of each major word, which suits headings. Sentence case capitalizes only the first word, like a normal sentence.

How do camelCase and snake_case handle spaces?

Both styles remove the spaces between words. camelCase joins words and capitalizes each one after the first, while snake_case joins them with underscores in lowercase.

Will converting change my original text?

No. Your input stays in place, and the converted version appears separately, so you can switch between styles without losing your starting text.

Does it work with non-English letters?

Case changes follow standard rules for many languages, though scripts without uppercase and lowercase forms (such as Chinese or Japanese) are left unchanged.
