How PDF Metadata Editor Works
Detailed guide to pdf metadata, privacy, and container structure.
PDF Information Dictionary vs XMP Metadata
PDF files maintain two separate metadata stores: the legacy /Info dictionary and the modern ISO 16684-1 Adobe XMP XML package. TagEditor synchronizes both stores to ensure metadata updates and deletions are reflected across all PDF readers.
Legal, Academic & Government Document Sanitization
Removing author and corporate metadata is mandatory before submitting legal evidence, responding to government bids, or entering double-blind academic peer reviews to prevent inadvertent identity disclosure.
Zero-Upload Client-Side PDF Engine
TagEditor manipulates cross-reference tables (XRef) and object streams entirely inside your browser memory using PDF-lib. Confidential contracts and financial records never touch an external server.
