How to password protect a PDF for free
Drop your PDF above, type a password twice, choose whether readers may print, copy or edit the document, and press Protect PDF. The encrypted file downloads straight away and asks for the password in every PDF reader — Acrobat, Chrome, Edge, Preview on Mac, and phone apps.
Why doing this in your browser matters
Most online tools upload your document to a server to encrypt it — which means a stranger's computer holds both your confidential file and the password you chose. EditZap encrypts the PDF locally with AES, so the file never leaves your device and the password is never transmitted anywhere.
