Protect Confidential Legal Exhibits for PACER Filing Free | Secure & Private

Legal exhibits being password protected for a PACER electronic filing
Filing confidential exhibits in US federal or state court? Protect sensitive trade secrets, proprietary business information, or private client data with a password before e-filing via PACER or CM/ECF. Lock your legal evidence safely here in your browser without your confidential data ever touching a cloud server. The American legal system relies heavily on the public accessibility of court records through systems like PACER (Public Access to Court Electronic Records). However, during the discovery and trial phases of litigation, attorneys often encounter documents that contain highly sensitive material that should not be part of the public domain. Whether you are filing 'Under Seal' or according to a Protective Order, ensuring that your digital exhibits are correctly encrypted is a core responsibility of legal counsel. In the digital age, a failure to secure confidential files can lead to the permanent exposure of a client's most valuable secrets. PdfXpo provides the professional security utility for US attorneys and legal professionals. Our platform utilizes advanced WebAssembly technology to encrypt and lock your legal PDF documents entirely within your local browser. This ensures that your client’s trade secrets, private communications, and financial records are protected with industry-standard AES encryption, and that neither the file nor the password itself is ever transmitted to our servers. We provide the security level expected by federal judges and corporate law firms with the ease of a free, barrier-free web utility.

Common Interrogatories

Expert Knowledge Base Resolved

Why should I password-protect confidential exhibits before PACER filing?

Federal court rules (FRCP 5.2) and local court orders often require the redaction or protection of highly sensitive data—such as trade secrets, financial records, and private client communications—filed as exhibits. Password-protection ensures that even if a file is accessed via the public PACER terminal, only those with the appropriate keys (as specified in a protective order) can review the confidential material.

Is it safe to lock my legal evidence on an online tool?

Most online tools are NOT safe because they upload your sensitive legal documents to their cloud servers before applying the password. This could potentially waive attorney-client privilege. PdfXpo is different: we use WebAssembly (WASM) to encrypt and lock your PDF entirely in your local browser memory. your evidence and the chosen password never leave your machine.

Will the court or opposing counsel be able to open the file?

Yes. Our tool uses industry-standard AES encryption compatible with professional PDF readers like Adobe Acrobat Pro and Bluebeam used by judges and law firms. When you file your exhibit via CM/ECF or share it during discovery, simply provide the password separately according to the court's protective order or discovery agreement.

Can I lock my deposition transcripts and exhibits after merging them?

Absolutely. Law firms often consolidate hundreds of pages of deposition testimony and related exhibits into a single 'Evidence Volume' first. You can use our 'Merge PDF' tool to combine your legal documents and then use the 'Protect PDF' tool to secure the final consolidated volume.

Do I need to sign up to use the legal exhibit record locker?

No. PdfXpo is 100% free with no signup required. we believe that attorneys and self-represented litigants should have access to bank-level security tools without having to share their data or pay for privacy during the litigation process.
