Text Case Converter

Text arrives in the wrong case all the time — a headline typed in lowercase, a file name in full caps, or a paragraph that needs clean sentence case for a report. The Text Case Converter fixes any of these in a single click. Paste your text, pick a format, and copy the result.

What the Text Case Converter does

The converter supports six common transformations. UPPERCASE and lowercase are self-explanatory. Title Case capitalizes the first letter of every word, which suits headlines and menu labels. Sentence case capitalizes only the first letter of each sentence — the standard for most body text. tOGGLE cASE flips the case of every character, useful for undoing accidental Caps Lock. Reverse Text reverses the entire string, which some people use for simple puzzle games and text effects.

Because everything runs locally in your browser with JavaScript, even long documents convert instantly, and your text never travels over the network.

Frequently asked questions

Is my text uploaded anywhere?

No. All conversion happens in your browser using JavaScript. Your text is not sent to our servers or stored anywhere.

Can I convert several paragraphs at once?

Yes. Paste as much text as you like — the converter preserves line breaks and applies the selected case to everything.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word ("The Quick Brown Fox"), while Sentence case only capitalizes the first letter of each sentence ("The quick brown fox").
