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.

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.
What people use it for
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.

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.
