Frequently Asked Questions
How secure is PDFVoid's local processing?
It is extremely secure. Because no passwords, keys, or file bytes ever traverse the network, your private documents remain 100% confidential.
Why should I manage security in the browser?
Uploading documents to cloud servers to encrypt or unlock them exposes files to data intercepts. Local execution guarantees that only you hold the keys.
Is there any fee or payment required?
No, all security and metadata tools on PDFVoid are free to use with no premium levels.
