Why PDFs can leak metadata
PDFs can contain document properties, XMP packets, author names, producer software, comments, annotations, forms, attachments, and JavaScript indicators. Some of this data is not visible when you simply open the PDF.
Safe PDF workflow
First scan the PDF with a privacy scanner. Review document properties, hidden objects, attachments, comments, forms, and redaction warnings. Then clean supported metadata and verify the cleaned PDF before emailing it.
Redaction warning
If a PDF contains black boxes over private text, do not assume it is safely redacted. True redaction removes underlying text, not only the visible overlay. Use a redaction checker where possible and review the output manually.
