Protect PDF

Add AES-256 password encryption on your device.

Local processing

Use a strong, unique password. FileStation cannot recover it. Encryption restricts opening the file; it does not prevent an authorized reader from sharing its contents.

Protect PDF: how it works

Set an opening password for a PDF using local AES-256 encryption. The file and password are processed in your browser.

  1. 1

    Choose an unencrypted PDF.

  2. 2

    Enter and confirm a password of at least 8 characters.

  3. 3

    Encrypt, download and verify the password in your PDF reader.

Before you start: Use a strong, unique password. FileStation cannot recover it. Encryption restricts opening the file; it does not prevent an authorized reader from sharing its contents.

Protect PDF FAQs

Can FileStation recover a forgotten password?

No. Keep the password safely and retain an appropriate original. The password is not sent to FileStation.

Are my documents uploaded?

Local PDF tools process documents in your browser. Choosing a file alone does not upload it. Server conversion sends the chosen file only after you confirm; server AI sends extracted text only after consent. Download your output before closing the page; there is no cloud document library.

Are my PDFs encrypted?

The website uses HTTPS to encrypt the connection. Local processing does not automatically password-encrypt your input or downloaded PDF. No website can guarantee 100% security; use a trusted device and keep your original files.

How do I save a PDF on an iPhone?

After creating the result, use Save / Share and choose Save to Files. If a download opens a preview, use the browser’s Share control to save a copy.
