Which case to use where
Sentence case (only the first word and names capitalised) is the default for most headlines and buttons today. Title Case Capitalises Every Main Word and suits book and film titles. UPPERCASE works for short labels, not paragraphs, because it is slower to read.
The code cases strip punctuation and join the words: camelCase for JavaScript variables, PascalCase for class names, snake_case for Python and databases, kebab-case for URLs and CSS classes, and CONSTANT_CASE for constants.
FAQs
How does Title Case handle small words?
Short words such as a, an, the, and, of, in and to stay lowercase unless they start or end the title, which follows most style guides. Proper nouns inside a sentence-case conversion still need a quick manual check.
Does it work with accented letters?
Yes. Upper and lower case use your browser’s Unicode rules, so é becomes É and ß becomes SS.
Is my text sent anywhere?
No. Everything runs in your browser.
