About Case Converter
Title Case keeps short words such as “of”, “and” and “the” lowercase unless they start the title. The programming cases work line by line, so you can convert a list of names at once; existing camelCase words are split correctly.
Everything runs in this browser tab: your text is never uploaded or stored, and the result updates as you type. It keeps working offline once the page has loaded.
