Text Case Converter

Change capitalization without retyping the text. Line breaks, spacing and punctuation remain in place while letter case changes.

How the modes differ

Lowercase and uppercase apply locale-aware browser transformations. Sentence case lowercases the text before capitalizing the first letter and letters after sentence-ending punctuation. Title case keeps common short connector words lowercase in the middle of a title.

Case conversion cannot infer names, acronyms or brand-specific capitalization. Review the result when those details matter.
