Uppercase Converter

When to use all caps

Uppercase text is used for headings, labels, acronyms, legal notices and emphasis. Long stretches of capitals are harder to read, so use them sparingly: readers recognize words partly by their shape, and capitals make every word a rectangle.

This converter changes every letter, including accented characters (é becomes É), and leaves numbers and punctuation alone. Special cases follow Unicode rules, so the German ß becomes SS.
