A PDF can carry other files inside it, and the format has had that ability for decades. It is how an electronic invoice ships its machine-readable XML inside the human-readable document, how a drawing can travel with its CAD source, and how a report can carry the spreadsheet its figures came from — one file to send, one file to archive, nothing to lose track of.

The attachment is embedded, not linked, so it goes wherever the PDF goes and works with no network at all. Existing attachments are listed before you add yours, so you can see what the document is already carrying. It is not visible on the page: readers show it in an attachments panel, which is worth mentioning to whoever receives it.

How it works

  1. Drop in the PDF.
  2. Choose the files to embed — you can add several.
  3. Check what the document already carries, listed above.
  4. Attach and save the new PDF.

What people use it for

  • Shipping the source spreadsheet inside the report that summarises it.
  • Sending an electronic invoice with its structured data embedded in the readable PDF.
  • Keeping a drawing and its CAD file together as a single archived document.

Frequently asked questions

Is my file uploaded to a server?
No. The file is opened by JavaScript and WebAssembly running inside your own browser tab. It is never uploaded, there is no server-side processing and nothing is stored — closing the tab discards everything.
Where does the recipient find the attachment?
In the reader's attachments or paperclip panel — it is not shown on the page. Desktop readers all support it; some mobile and in-browser viewers do not show the panel at all, so it is worth saying in your covering message that the file is in there.
Does attaching make the PDF much bigger?
By the size of what you attach, plus a little. The file is embedded whole, so a 10 MB spreadsheet adds about 10 MB — which is the point, since it travels with the document rather than depending on a link that may rot.
Can I attach anything?
Technically yes, but consider the recipient: many mail gateways scan inside PDFs and will quarantine one carrying an executable or an archive. Documents, images and data files travel without trouble.
How do I get attachments back out?
With the Extract attachments tool, which lists everything embedded in a PDF and saves it out individually or as a ZIP.
