Which case is which?
Title Case capitalizes words the way headlines and book titles do. Sentence case capitalizes only the first letter of each sentence, which is easier to read in long text. It’s also the quickest fix for text that was typed with Caps Lock on.
Programmers use the others for names in code: camelCase (userName) and PascalCase (UserName) for variables and classes, snake_case (user_name) in Python and databases, kebab-case (user-name) in URLs and CSS, and CONSTANT_CASE (USER_NAME) for constants.
Frequently asked questions
Is the case converter free?
Yes, completely free. There is no sign-up, no watermark, no daily limit and no premium plan.
Is my text sent anywhere?
No. Everything happens in your browser. Your text is never sent to a server or saved by us, so nobody (including us) can see it. You can even disconnect from the internet after the page loads and the tool keeps working.
How do I fix text typed in Caps Lock?
Paste it and choose Sentence case. Then check names and places, which may need their capital letters back.
Can it remove extra spaces and line breaks?
Yes. It can clean up extra spaces and remove line breaks, which is handy for text copied from a PDF or an email.
What is kebab-case?
Words written in lowercase and joined with hyphens, like my-page-title. It’s common in web addresses and CSS class names.
