PDF files contain hidden metadata properties—including document title, author name, subject, creation date, software producer, and keywords. Outdated or inaccurate metadata looks unprofessional in search engines and browser tabs, while unwanted author tags can leak private personal information when sharing files publicly. PDFPK’s PDF Metadata Editor lets you view, edit, or sanitize metadata in seconds directly from your browser.

PDF specifications support two metadata architectures: the classic Document Information Dictionary (`/Info` object) containing standard key-value pairs (Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate), and modern Extensible Metadata Platform (XMP) metadata streams containing serialized XML packets. Discrepancies between the `/Info` dictionary and the XMP stream can cause search engines to display old titles. PDFPK synchronizes these metadata dictionaries to guarantee uniform presentation across all viewers and indexers.
When submitting public court records, government tenders, or competitive commercial bids, unscrubbed metadata can accidentally expose the names of junior staff, internal network drive paths, template origins, or previous client names. Scrubbing metadata prior to document publication is a standard cybersecurity best practice.

When a PDF is viewed in a web browser, the tab displays the internal PDF "Title" metadata rather than the filename. Using our editor to update the Title field fixes this immediately.
