How to Review and Remove PDF Metadata
Reduce accidental disclosure from properties and embedded document features.
Know where metadata lives
PDFs may contain title, author, subject, keywords, application names, timestamps, XMP packets, comments, attachments, form values, bookmarks, and revision history. Editing the visible author field does not sanitize everything.
Clean a copy
Review document properties, remove unnecessary comments and attachments, flatten or clear form data when appropriate, and export a fresh file. Avoid preserving incremental updates when prior states are sensitive.
Verify independently
Reopen the output, inspect properties and attachments, search for confidential names, and use a metadata inspection tool for high-risk releases. Sanitization should be part of a broader disclosure review.
