Sending a sensitive PDF by email is convenient, but email itself isn't private -- forwarded threads, shared inboxes, and simple mistakes happen. Protect PDF adds a password so the file can't be opened by anyone it wasn't meant for.
How to password-protect a PDF
- Open Protect PDF and upload your document.
- Set a password.
- Apply the protection.
- Download the protected PDF and send it.
Sharing a protected PDF safely
- Send the password separately from the file -- a text message or phone call, not the same email thread.
- Use a password the recipient can actually type -- a shared reference (like the last four digits of an account) rather than something illegible.
- Remove protection later with Unlock PDF once it's no longer needed.
Frequently asked questions
What happens if someone without the password tries to open it?
They'll be prompted for a password and won't be able to view the content without it.
Can I remove the password later?
Yes -- use Unlock PDF once you have the password and no longer need the protection.
Does protecting a PDF change its content?
No -- only access to the file is affected, not the content inside it.
Is my file uploaded to add the password?
No -- protection is applied entirely in your browser.
A password is the simplest safeguard there is -- try Protect PDF before your next sensitive send.
