How to Use the Case Converter

Paste your text in the input box and click any conversion button. The result appears instantly in the output box. Use UPPERCASE for headings and emphasis, lowercase for normalizing text, Title Case for headlines and titles, and Sentence case for paragraph formatting.

Toggle case inverts each character, turning uppercase to lowercase and vice versa. All processing is done locally in your browser — your text stays private.
