PDF Sanitizer Tool

Sanitize your PDF documents by stripping out hidden metadata that could reveal personal or organizational information. Works entirely in your browser.

Part of our Remove PDF Metadata suite

About This Tool

Sanitizing a PDF goes beyond casual cleanup — it's about making sure a document is safe to release into the wild. Government agencies, law firms, healthcare organizations, and financial institutions all deal with documents where a stray metadata field could expose confidential information. An author name might identify a case officer. A timestamp might reveal when a sensitive decision was made. A producer field might disclose which classified system generated the file. This sanitizer inspects every metadata field in your PDF and removes them entirely, producing an output that carries zero identifying markers about its origin. All processing runs locally in your browser using client-side JavaScript, which means the sensitive document you're trying to protect never gets transmitted anywhere. No upload, no server-side processing, no logs.

How It Works

1

Upload Your PDF

Drag and drop or click to select the PDF you want to inspect and clean

2

Review the Metadata

See every hidden field — author, creation date, software used, title, subject, and more — laid out in a clear table

3

Remove & Download

Strip out all metadata with one click and download a clean PDF ready to share

Who Uses This Tool

Government Records Officers

Classified Document Declassification

Sanitize metadata from declassified government documents before public release to prevent accidental disclosure of system names or personnel

Litigation Support Teams

Legal Discovery

Remove metadata from documents produced during litigation discovery that could inadvertently reveal privileged information about the drafting process

Healthcare IT Teams

Healthcare Record Sharing

Sanitize patient-facing documents so that internal system identifiers, staff logins, and EHR software details aren't shared with patients or insurers

Internal Audit Departments

Financial Audit Documentation

Clean audit workpapers and reports before sharing with external auditors or regulators so internal reviewer names and draft iterations are not visible

Pro Tips

Sanitize Every Outbound Document

If your organization handles sensitive information, make metadata sanitization a mandatory step before any document leaves the building — digitally or physically.

Create a Sanitization Checklist

Pair metadata removal with other sanitization steps: check for hidden layers, embedded comments, revision history, and tracked changes before releasing a document.

Test with Your Own Files First

Run a few internal documents through the viewer to see what metadata your organization's tools are embedding. The results will inform your sanitization policy.

Document the Process

For compliance purposes, keep a log noting that metadata was removed from a document before release. You don't need to save what was removed — just that the step was completed.
