I typed a text with Caps Lock on by mistake, can I fix it?

Yes. Paste it and press "iNVERT": every uppercase letter becomes lowercase and vice versa, recovering the text the way you meant to type it.

Does the converter keep accents and special characters?

Yes. It uses locale-aware casing, so accented letters are converted correctly between upper and lower case.

What each mode is for

Sentence case capitalises only the first letter of each sentence, the normal way to write running text. Title Case capitalises the first letter of every word, common in English headlines. iNVERT swaps uppercase for lowercase and vice versa: very handy when you've typed something with Caps Lock on by mistake.

The converter uses the browser's locale-aware casing, so accented characters are handled correctly. Everything is processed in your browser.
