The Case Converter rewrites your text in whichever capitalisation style you need — uppercase, lowercase, sentence case, title case or alternating case. Paste the text, choose a style, and the converted version appears immediately, ready to copy. It saves retyping when a heading arrives in the wrong style, when a pasted block came through in all capitals, or when a title has to follow a house style guide. Punctuation and spacing are left exactly as they were, so only the letters change, and the conversion is done entirely in your browser with nothing sent to a server.
