About This Tool
PDFs can carry other files inside them, which is one of the format most useful and least known capabilities. The report and the spreadsheet behind its numbers travel as a single document, and cannot be separated in a forwarded email.
Any file type can be embedded - XLSX, CSV, images, ZIP archives, source documents. Each attachment gets a description, so the recipient understands what they are looking at rather than finding an unexplained file called data_final_v3.
Attachments appear in the attachments pane of Acrobat and most desktop readers, where they can be opened or saved out. Browser-based viewers vary in whether they surface them, so it is worth mentioning the attachments in the document text as well.

One file to upload, carrying everything the reviewer needs.
Frequently Asked Questions
Which file types can I attach?
Any. PDF treats attachments as opaque data, so spreadsheets, images, archives and source files all work.
How does the recipient get them out?
Through the attachments panel in Acrobat, Preview and most desktop readers. Browser viewers are less consistent, so mention them in the document text.
Does this make the PDF much larger?
It grows by roughly the size of the attached files, since they are stored as-is.
Are attachments encrypted with the document?
If you password-protect the PDF afterwards, the attachments are protected too.
