Questions
What makes this different from pressing Caps Lock?
Caps Lock only affects new keystrokes. This converter transforms whatever you paste all at once, including text that was already typed or copied elsewhere.
Does it handle accented and international characters?
Yes. The conversion uses locale-aware rules, so characters like é become É and ü becomes Ü.
What happens to numbers and punctuation?
Numbers, symbols, and punctuation marks have no uppercase form and are left exactly as they are.
Is my text sent to a server?
No. The conversion runs entirely in your browser. Your text never leaves your device.
