Frequently asked questions

Does the case converter keep my line breaks?
Yes. Line breaks are preserved for most cases. Programming styles like camelCase and snake_case join words together by design.
Does it store my text?
No. Your text is processed entirely in your browser and is not sent to a server or saved anywhere.
Which case should I use for URLs?
kebab-case (lowercase words separated by hyphens) is the most common and readable format for URL slugs.
What is the difference between Title Case and Capitalize Each Word?
Title Case lowercases the remaining letters of each word, while Capitalize Each Word only uppercases the first letter and leaves the rest untouched.
Is the case converter free?
Yes, it is completely free and requires no account or sign-up.
