Uppercase or Lowercase Any Text
If you need to change the case of any specific words or phrases, you can let DuckDuckGo do it for you in a matter of seconds.
All you need to do is write uppercase or lowercase or titlecase and then enter the words you want to convert. The first result will give you the text you entered in the case you chose.
Granted, this feature is a bit basic since you can’t further customize it, but it’s still worth knowing for when you really need it.
