Why Password Protect Your PDFs?

Frequently Asked Questions

How strong is the encryption?

We use AES-256 encryption, which is the industry standard used by banks and governments.

Can I remove the password later?

Yes. Open the protected PDF with the password, then save it as a new unprotected file using any PDF editor.

Is my file uploaded anywhere?

No. The encryption runs entirely in your browser using JavaScript. Your file stays on your device throughout the process.
