Protect PDF with Password

Why protect a PDF with a password?

PDFs often contain private information contracts, invoices, tax documents, medical forms, or internal reports. Password protection adds a layer of security by requiring a password before someone can open the file.

Protecting a PDF with GhostConvert is useful when you:

• Email a PDF that includes personal or business information.
• Share documents with clients and want basic access control.
• Upload a PDF to a shared drive and reduce accidental access.
• Store sensitive paperwork in a safer, encrypted format.

Use this tool only for PDFs you own or have permission to encrypt and share.

How PDF password protection works

1. Upload a PDF from your computer, phone, or tablet.
2. Enter a password you want to require for opening the PDF.
3. GhostConvert encrypts the document and generates a protected copy.
4. Download the encrypted PDF and share it securely.

Important: keep your password safe. If you forget it, the encrypted PDF may not be recoverable.

Tips for best results

• Use a strong password with a mix of letters, numbers, and symbols.
• Send the password separately from the file (for example, via text instead of email).
• If you only need printing/copying restrictions (not a password), use Unlock PDF for owner restrictions workflows.

Frequently asked questions

Does this encrypt the PDF or just lock it?

Password protection typically encrypts the PDF so that the content cannot be opened without the password. The exact encryption details depend on the PDF settings used during processing.

Can GhostConvert remove the password later?

If you know the password, you can create an unlocked copy in your own workflow. If you forget the password, GhostConvert cannot recover it.

How long are my files stored?

Files are kept only long enough to apply protection and provide your download link briefly. They are deleted automatically after a short period as described in the Privacy Policy.
