List, Rename or Delete PDF Attachments
Clean up the hidden payload of a PDF without altering a single visible page. Run the tool with empty options to get a plain-text listing of every embedded attachment; then rename misleading file names or delete files that should not ship with the document. The visible content — pages, text, images — is preserved exactly, only the attachment list changes. All processing happens locally in your browser.

How to edit attachments
- Upload the PDF and run the tool once with empty options to list its attachments.
- Enter renames as old=new pairs and/or names to delete, separated by commas.
- Download the updated PDF with the cleaned-up attachment list.
Frequently asked questions
How do I see which attachments a PDF contains?
Run the tool with both fields empty — instead of an edited PDF you get a small text file listing every embedded attachment by name.
Does renaming or deleting attachments affect the pages?
No. Only the embedded file entries in the document structure change; every page remains visually identical to the original.
What happens if a name I typed does not exist?
The tool stops and reports the mistake together with the current attachment names, so you can correct the spelling and run it again.
