What Does Sentence Case Do?
Sentence case makes only the first letter of each sentence uppercase and converts the rest to lowercase. It’s the most natural, reader-friendly style for blog posts, emails, essays, documentation, and social media captions.
Is This Tool Safe?
Yes — the conversion happens entirely in your browser. Your text is not uploaded, stored, or sent to any server.
