Frequently Asked Questions

What is the difference between Title Case and Sentence case?

Sentence case only capitalizes the very first letter of the sentence (and proper nouns). Title Case capitalizes the first letter of almost every word, ignoring small conjunctions like ‘and’ or ‘the’.

Will it mess up acronyms?

When converting to lowercase or Title Case, the tool will adjust all letters. You may need to manually re-capitalize specific acronyms (like NASA or USA) after the conversion.

Is my text kept private?

Yes, the formatting is done entirely locally in your web browser. Your text is never transmitted over the internet.
