Open VSPIC Protect PDF, load your document, enter open and permissions passwords, configure restrictions, and download the encrypted PDF. Encryption runs locally in your browser — no subscription, no cloud upload, no IT ticket for software installs. HR teams protect offer letters, lawyers secure settlement drafts, and founders share cap tables under access control.

An open password (user password) requires recipients to enter a secret before viewing any page — use for confidential content. A permissions password (owner password) lets recipients open the PDF but restricts printing, copying, or editing depending on settings you choose. Combine both when you need viewing gated by passphrase plus limited actions after entry.

Yes. Your document bytes never leave your device during Protect PDF operations. This matters for HIPAA-sensitive packets, unreleased financial statements, and personal legal documents you refuse to place on third-party servers. Load protect-pdf once; encryption completes even offline after the page assets cache.

Standard PDF readers on iOS, Android, Windows, and macOS prompt for the open password you set in VSPIC. Share passwords through a separate secure channel — not the same email as the attachment when threat models require it. Test one device before mass distribution to confirm recipients use compatible reader apps.

Permissions restrictions deter casual copying and printing in compliant readers, but determined users with specialized tools may bypass weak restrictions — no consumer PDF encryption is perfect against skilled attackers. For high-stakes scenarios, combine legal agreements with encryption rather than relying on technical barriers alone. VSPIC implements standard PDF security suitable for everyday business confidentiality.

Either order works, but compress first if file size reduction is the priority, then protect the smaller output before emailing. Some workflows protect masters and generate compressed unencrypted copies for public distribution — keep track of which version you send to which audience. Unlock PDF removes protection later when you hold the owner password.

Yes. Merge PDF first, then protect the combined document with one password covering all exhibits. Clients receive a single encrypted attachment instead of many loosely secured files. Document the password in your cover email or secure portal, not in the PDF filename.

PDF encryption is designed to be difficult to reverse without the password. Store owner passwords in your team password manager before distributing protected files. VSPIC cannot recover lost passwords because encryption occurs client-side without our servers retaining keys. Keep unencrypted archival masters in secure storage.
