What is PDF attachment extraction?

Some PDFs contain embedded files inside the document. Extraction pulls those files back out so you can open or download them separately.

Tool description

This tool scans a PDF for embedded attachments and shows them in a file tree. You can download each attachment on its own or export everything as a ZIP archive.

Features

  • Finds embedded attachments inside a PDF
  • Lets you download individual files or everything at once as ZIP
  • Preserves unique file names when attachments share the same name

How it works

The tool reads the PDF in the browser with PDF.js, collects the attachment metadata and byte content, and builds a downloadable file tree. If multiple attachments would land on the same path, the tool renames later ones with a numbered suffix.

Notes

  • This only extracts embedded files. It does not OCR pages or pull text from the document body.
  • A PDF with no attachments will show a warning instead of an empty download list.
