How it works

Uppercase and lowercase change every letter. Title case capitalises the first letter of each word. Sentence case capitalises the first letter of each sentence and makes the rest lowercase. For camelCase, snake_case and kebab-case the tool splits your text into words, removes punctuation and joins the words in the chosen style.

Frequently asked questions

What is the difference between title case and sentence case?

Title case capitalises every word, as in a book title. Sentence case capitalises only the first word of each sentence, as in normal writing.

What are camelCase, snake_case and kebab-case used for?

They are naming styles used in programming and web addresses. camelCase joins words with capitals, snake_case joins them with underscores, and kebab-case with hyphens.

Can I undo a conversion?
