Strip author names, creation timestamps, and software versions with zero upload.
What Metadata is Hidden Inside Your PDF?
Standard PDF specification (ISO 32000) includes two main metadata storage locations: the Document Information Dictionary (Info dict) and the Extensible Metadata Platform (XMP) XML packet. Common properties include:
- Author: Full name of the user account that authored or printed the document.
- Creator & Producer: Exact software build (e.g. "macOS Version 14.2 Quartz PDFContext" or "Microsoft Word 2021").
- Creation & ModDate: Exact second-level timestamps and timezone offsets revealing when and where edits took place.
- Title & Subject: Previous working document titles and internal project labels.
Why Sanitizing Metadata Protects Privacy
In legal discovery, investigative journalism, corporate bidding, and whistleblowing, accidental metadata leaks have repeatedly compromised identities and disclosed confidential client relationships.
