Does it affect numbers and punctuation?

No — only alphabetic characters are uppercased. Numbers, punctuation, and symbols remain unchanged.

Can I convert multiple paragraphs at once?

Yes, the tool handles any amount of text including multi-paragraph content.

Is this the same as pressing Caps Lock?
