PDF Metadata Cleaner & Sanitizer
Inspect and sanitize PDF Document Information Dictionaries (/Title, /Author, /Subject, /Keywords, /Creator, /Producer) and embedded XMP metadata streams.
This tool sanitizes standard document properties (/Title, /Author, /Subject, /Keywords, /Creator, /Producer, /CreationDate, /ModDate) and embedded XMP metadata streams. Removing metadata does not guarantee removal of hidden PDF content, annotations, embedded attachment files, or underlying incremental revision history.

How It Works
Processing location depends on the selected tool and mode. Browser-based tools process files locally; advanced image processing may send the selected file to the ZeroMeta processing endpoint. Files are not intended to be stored permanently.

Dictionary Sanitization
Our client-side parser identifies the Info Dictionary and XMP packets, purging author names and modification dates.

Frequently Asked Questions
What metadata is typically embedded in PDFs?
PDFs frequently store the full name of the author, computer username, original software used (Microsoft Word, Canva, InDesign, Google Docs), operating system, and exact creation and modification timestamps.
Will this affect my PDF text formatting or signatures?
No. The document's visual layout, fonts, and page contents are preserved intact. Note that if a PDF contains cryptographic digital signatures, modifying headers will invalidate the signature hash, requiring re-signing.
