A note on Title Case

This converter capitalises the first letter of every word, including short words such as “a”, “of” and “the”. Style guides such as AP and Chicago keep those small words lowercase unless they come first, so for a newspaper-style headline, convert first and then lower-case the small words by hand. Sentence case also lowercases names, so re-capitalise people, places and brands afterwards.

Frequently asked questions

Can I undo a conversion?

A button replaces the text in the box, and most browsers cannot undo that with Ctrl+Z. Keep your original text somewhere else, or paste it in again, if you might need it.

Does it work with accented and non-English letters?

Yes. Uppercase and lowercase work for every alphabet that has capitals, such as French, German, Spanish and Russian (Turkish dotted and dotless i may need a manual check). Scripts without capitals, like Urdu and Arabic, are left as they are.

Is there a length limit?

No practical limit. Even a long document converts instantly because everything runs in your browser.
