How to use this PDF tool

  1. Select one PDF.
  2. Review the scope and start the local analysis.
  3. Check the on-page summary, then download the JSON report.

What this tool does

This tool reads the embedded-files name tree made available by the browser PDF parser. It does not open or execute attached content.

Attachment entries are enumerated, measured, and summarized. File bytes remain in memory only while the report is prepared.

Some portfolio packages or encrypted PDFs may hide attachments from browser-based parsers.

Supported formats

This page accepts standard PDF files readable by PDF.js. Password-protected, damaged, unusually large, and dynamic XFA documents may be unsupported.

Tips for better results

  • Use original PDFs rather than scans of printed pages.
  • For comparisons, select the older PDF first and the revised PDF second.
  • Verify flagged findings in a desktop PDF viewer before production use.

FAQ

Does PDF Attachment Inspector upload my PDF to a server?

No. The PDF is read by JavaScript in your browser. The page does not add a file-upload request.

Can PDF Attachment Inspector read password-protected PDF files?

A PDF that requires a password may not open. Remove authorized encryption first, then run the inspection again.

What does the downloaded PDF Attachment Inspector report contain?

The JSON report contains the source file names, analysis time, supported findings, and tool-specific differences or warnings.

Will PDF Attachment Inspector work with very large PDFs?

Large or image-heavy PDFs can use substantial memory. Close other tabs and test a smaller copy if the browser becomes slow.

How accurate is PDF Attachment Inspector for production preflight?

Some portfolio packages or encrypted PDFs may hide attachments from browser-based parsers. For regulated or press-critical work, confirm the result with a dedicated desktop preflight application.
