What types of files can be embedded in PDFs?

Any file type can be embedded: spreadsheets, images, other PDFs, Word documents, data files, source code, and more. PDFs used for regulatory submissions often embed source data. PDF portfolios can contain dozens of attached documents of various types.

How do I know if a PDF has attachments?

Many PDF viewers show a paperclip icon when attachments are present. Our tool scans the PDF structure and lists all embedded files regardless of how the PDF viewer displays them. Some attachments are deeply embedded and not visible in basic viewers.

Can I extract from PDF portfolios?

Yes. PDF portfolios (also called PDF packages) are PDF files containing multiple embedded documents. The tool extracts all items from the portfolio, listing each with its filename, size, and type.

Is this useful for forensic document analysis?

Yes. Examining PDF attachments is part of digital forensics and compliance audits. The tool reveals all embedded content including files that may not be visible in standard viewers, helping auditors understand the full contents of a PDF package.
