The document-security jobs, done where they belong — on your own machine. Encrypt a file, remove a password you have, sign it, or genuinely remove sensitive content. Uploading a file to secure it is backwards, and none of these do.

Add a password and encrypt the file.
Unlock PDF
Remove a known password from a PDF.
Sign PDF
Draw or type your signature onto a document.
Redact PDF
Black out sensitive text or images and truly remove them.
