What encryption actually does

Encrypting a PDF is about more than just a password prompt. This tool uses AES-256—the global industry standard for data security—to scramble the actual contents of the file. Without the correct key, the data is just a meaningless jumble of bytes. It's the same level of protection used for bank records and government documents, so you can trust that your information is actually safe.

User password vs. Owner password

There are two different ways to lock a PDF, and we've given you control over both:

• User Password: This is the "gatekeeper." Anyone who receives the file will need this password just to open and read it. If you're sending a private contract or medical records, this is the one you need.
• Owner Password: This controls what people can do *after* they open the file. You can restrict printing, editing, or even just copying the text. It's optional—if you leave it blank, we'll just use your User Password for everything.

A quick tip on password safety

Because the encryption is "real," there is no "Forgot Password" button. If you lose the password, the data in that file is gone for good—even we can't recover it. Always keep a copy of your password in a safe place, and always share the password through a different channel than the file itself (like a quick text or a phone call).

Your privacy comes first

We're handling your sensitive data, so we keep things strictly ephemeral. Your file is processed on a secure server and wiped clean the moment the encryption is finished. We don't store your files, we don't log your passwords, and we certainly don't look at your content. It's just a fast, secure way to keep your information private.
