When you need it

It happens all the time: a list of names arrives in all caps, a headline is typed in lowercase, or Caps Lock was left on. Retyping is tedious; with this tool you fix it in a second and copy the result with one click. Note that Title Case applies capitals to every word, including small words like "of" and "the": adjust those by hand if your style guide requires it.

Frequently asked questions

Are accented letters converted?

Yes: é becomes É, ñ becomes Ñ and so on, and vice versa.

Is my text stored anywhere?

No. Everything happens in your browser: the text is not sent to any server.

Does Title Case leave small words in lowercase?

No, it capitalises every word. If your style guide keeps words like "of", "and" or "the" in lowercase, adjust them by hand after converting.
