PDFs can carry embedded file attachments — spreadsheets, images, original source files — that are invisible unless you know to look. PDFStream lists all attachments and makes them available for download. The tool reads the PDF's embedded file stream and presents each attachment with its filename and type. Download any or all attachments individually. Use cases: recovering an Excel file attached to a PDF report, extracting source files embedded by an engineer in a technical document, accessing a JPEG attached to a PDF form, or auditing a document for unexpected embedded content before sharing externally.
