About this tool
UPPERCASE, also called all caps, writes every letter as a capital. It is the strongest way to make text stand out, so it is used sparingly in headings, labels, warnings and acronyms.
This tool changes only the letters. Numbers, punctuation, spaces and line breaks stay exactly as you typed them, so you can paste a whole document and keep its layout.
Example
hello world, this is a testHELLO WORLD, THIS IS A TESTWhen to use it
- Headings, buttons and labels in a design that calls for capitals
- Fixing text that was typed with Caps Lock on by mistake
- Writing acronyms, codes and constants
- Making warnings or notices easy to spot

Questions
Is all caps hard to read?
In long passages, yes. Readers recognise words partly by their shape, and capitals make every word a similar rectangle. Use all caps for short phrases and keep body text in normal case.
Does it change numbers or symbols?
No. Only letters are converted. Digits, punctuation and line breaks are left alone.
What about accented letters?
Accented Latin letters such as é, ñ and ü are converted to their capital forms too.
