Search "edit PDF online" and almost every result uploads your file to a server. If your document is sensitive, that's a problem — you're trusting a stranger's cloud and a delete-later promise.
Kameleo is the exception: it ships the PDF engine to your browser, so your file is read, edited and saved locally and never transmitted. Open your Network tab and watch — no upload happens. That's the whole point.
