Convert text between UPPERCASE, lowercase, Title Case, camelCase, snake_case, and more. One click to transform.
Title Case capitalizes the first letter of every word. It is commonly used for headlines, book titles, and article titles. For example, "the quick brown fox" becomes "The Quick Brown Fox".
Sentence case capitalizes only the first letter of the first word in each sentence, just like regular prose. It is the most natural and readable case for body text, subtitles, and UI labels. For example, "this is a sentence. and another one" becomes "This is a sentence. And another one".
camelCase is widely used in programming for variable and function names in JavaScript, Java, and many other languages. Words are joined without spaces, and each word after the first is capitalized: "hello world" becomes "helloWorld".
Both join words in lowercase, but snake_case uses underscores (common in Python and Ruby) while kebab-case uses hyphens (common in CSS and URLs).
