Why use the Case Converter?
Fixing capitalisation by hand is tedious, especially when a headline was typed in capitals or a list of product names is inconsistent. Title Case and Sentence case keep blog headings, social captions and email subjects tidy and on-brand, while camelCase, kebab-case and snake_case are handy for developers naming variables, CSS classes, files and URL slugs. The text is converted instantly in your browser and is never sent anywhere.
Frequently asked questions
Which words stay lowercase in Title Case?
Short articles, conjunctions and prepositions such as "a", "and", "of" and "the" stay lowercase unless they are the first or last word, following common headline style.
Should blog headings use Title Case or Sentence case?
Either is fine — consistency matters more. Many modern brands and publications prefer Sentence case because it reads more naturally.
Will Sentence case keep brand names capitalised?
No. It lowercases everything except the start of each sentence and the word "I", so check proper nouns afterwards.
What is the difference between kebab-case and snake_case?
kebab-case joins words with hyphens, which suits URLs and CSS classes. snake_case uses underscores, which is common in databases and some programming languages.
