NOPPAWUppercase Converter
The Uppercase Converter turns any text into ALL CAPS as you type. Reach for it when a form demands capital letters, when a heading needs to shout, or when you are preparing labels, acronyms and legal notices where uppercase is the expected style. The result updates live, so there is no button to hunt for.
