Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, while Sentence case capitalizes only the first letter of each sentence — like normal prose.
What are camelCase, snake_case, and kebab-case for?
They're naming conventions used in programming. camelCase joins words with capitals (myVariable), snake_case uses underscores (my_variable), and kebab-case uses hyphens (my-variable).
Will it keep my line breaks?
Yes, the basic cases preserve your formatting. The programming cases collapse separators into a single joined identifier by design.
Is there a length limit?
No practical limit. Because the conversion runs in your browser, you can process large blocks of text instantly and privately.
