Tips for better results

Works with other languages

Letters that have uppercase and lowercase forms, such as accented Latin letters, are converted too. Scripts without capitals, such as Arabic, stay as they are.

Free and private

The converter runs in your browser. Your text is never uploaded or stored, and there is no sign up or login.

Frequently asked questions

Is there a character limit? There is no fixed limit, though very large texts may be slower on older devices.

Can I undo a change? Press the Ctrl+Z (or Cmd+Z) keys inside the text box, or paste your original text again.
