User password gates opening; owner password restricts printing, copying, and editing. Client deliverables usually need both: open-secret for the client, strict owner rules against forwarding misuse.
12+ random characters for confidential files; PDF encryption resists casual opening but not nation-state cracking. Truly sensitive material needs stronger containers.
Anyone with the owner password can — that is by design. Protection deters casual misuse; it never survives a determined recipient with credentials.
No — encryption runs locally in your browser. Passwords never leave your device; only the final save touches the network — downloads are unlimited.
