Common Questions
What is the difference between Title Case and Capitalize Each Word?
Capitalize Each Word capitalizes every word. Title Case follows headline rules, keeping small words like "and", "of", and "the" lowercase unless they start the title.
Is there a limit on how much text I can convert?
There is no fixed limit. Because the conversion happens on your own device, you can convert anything from a single word to long documents.
