Password Protect Your PDFs Without Data Leaks

Sending sensitive financial documents or health records via email is incredibly dangerous. Adding a password to your PDF is the best way to ensure only the intended recipient can read it.

The Hypocrisy of Cloud PDF Encryptors

It makes no sense to secure a document by uploading it to an unsecured cloud server first. Most free tools require you to send your highly confidential, unencrypted file to their servers in order to add the password. This is a massive compliance risk for businesses and Chartered Accountants.

100% Local Encryption

PDF Pro processes your file entirely on your device. We load your PDF directly into your Chrome or Safari browser, apply the password, and save the file back to your hard drive. Your unencrypted file is never uploaded to the internet. Zero cloud storage. Total privacy.

Frequently Asked Questions

Can PDF Pro recover my password if I forget it?

No. Because the encryption happens entirely locally on your device, we do not have access to your document, nor do we store your password.

Is my unencrypted PDF uploaded to your servers?

No. The entire password protection process happens directly inside your web browser. We never upload, view, or store your documents.

PDF Pro tools are 100% cloud-based and secure. Your documents are processed with end-to-end encryption.
