What this tool does

Remove embedded-file name trees and associated-file references while keeping the visible PDF pages intact.

The tool deletes EmbeddedFiles entries from the catalog Names dictionary and removes catalog-level associated-file references before saving a new PDF.

Attachments stored in unusual custom structures may require a desktop forensic tool.

Supported formats

Standard, unencrypted PDFs. Portfolio presentation settings may remain, but their embedded-file collection is removed.

  • Keep the original file until you have checked the result.
  • Close memory-heavy tabs before processing large documents.
  • Use a short page range for a quick test.
  • Signed or encrypted PDFs need special care.

FAQ

Does this remove files embedded in a PDF portfolio?

It removes the standard EmbeddedFiles name tree and catalog associated-file references used by most portfolios.

Will the visible PDF pages change?

The page content is preserved, although rewriting can change file size and invalidates existing signatures.

Can hidden attachments remain in unusual PDF objects?

Possibly. This browser tool targets standard attachment structures, not arbitrary bytes hidden in custom objects.

Can I remove attachments from an encrypted PDF?

Not with this tool. Use an authorized unlocked copy first.

Will attachment annotations on pages be removed?

The embedded-file store is removed; unusual file-attachment annotations may remain visually but no longer resolve normally.
