Protect PDF on Mac
Preview can password a PDF — through an export dialog most Mac users never find. The browser route is findable: upload, password, download the encrypted copy. Free with fair daily limits.

Why use our Protect PDF

Free to start
Core tools are free with daily limits — no install required.
Works anywhere
Runs in your browser on any device, anywhere in the world.
The discoverability problem
macOS hides PDF protection inside File → Export → checkbox — functional once found, forgotten by next time. The browser tool is a bookmark: same real encryption, no menu spelunking.
Same rules everywhere
Strong passphrase, recorded somewhere safe, shared by a channel other than the file's — and the permanent truth that no one, us included, recovers a lost password. Archive an unprotected original first.
