Extract PDF Attachments
Find files embedded inside a PDF and download selected parser-supplied attachment bytes without opening or uploading them.
PDF bytes and inspection results stay in browser memory. Attachments, links, actions, and external destinations are never opened, executed, or fetched.

A PDF attachment is a separate file stored inside the PDF rather than visible page content. This tool lists parser-exposed embedded files, then creates a download or ZIP only when you explicitly request it.
How OpenFileTools processes it
Local processing, explicit choices.
PDF.js exposes the attachment catalog and parser-supplied content bytes in the managed session. OpenFileTools checks byte limits, keeps the content inert, and creates a browser download or existing-helper ZIP only after an explicit request.
Questions, answered.
What is a PDF attachment?
It is a separate embedded file stored in the PDF, such as a spreadsheet, image, or source document.
Does selecting an attachment open it?
No. Selection only plans a browser download; OpenFileTools never executes attachment content.
Are attachment bytes uploaded?
No. Catalog inspection, content handling, and ZIP creation stay in this browser tab.
