About the Free Case Converter
Writers, students and developers often need to change the case of a block of text: an essay title in Title Case, a heading in UPPERCASE, or a sentence that was typed in all caps. Doing it by hand is slow and error-prone. Our case converter changes every word in seconds, and it keeps your punctuation and spacing exactly as they were.
Title Case capitalises the first letter of every word, Sentence case capitalises the first letter of each sentence, UPPERCASE makes every letter capital and lowercase makes every letter small. The converted text appears below your original, ready to copy. Nothing is uploaded or stored — the conversion runs in your browser.
