How it works

How it works

One file, one password, one encrypted copy back. Originals stay on your device.

1

Drop your PDF

Add a single PDF up to 100 MB. The original on your device is not modified; you'll get a separate encrypted copy.

2

Set a password

Type the password twice. There's no recovery if you lose it, so keep a copy somewhere safe before you encrypt.

3

Download the encrypted PDF

Click Add Password Protection. The encrypted PDF is ready to download. Sharing the file requires sharing the password too.

Use cases

What people use it for

Sending tax or financial paperwork

When a tax return or pay stub goes by email, an open password keeps it private even if the email is forwarded by mistake.

Sharing medical documents

Lab results, prescriptions, and clinic letters often contain identifying information. Encrypting before sharing is a quick line of defence.

Sending IDs to landlords or banks

If you need to email a passport or licence scan, password-protect it and share the password by a different channel (text, voice, separate email).

Internal handoffs of sensitive data

HR letters, legal drafts, and offer letters can be password-protected before going through company email or cloud storage.

FAQ

Frequently asked questions

AES-256, the same encryption standard used by recent versions of Adobe Acrobat. It's strong enough that a long random password cannot be brute-forced in any practical timeframe.
