Is there a limit to either the amount of attachments, or file size, that can be added to a single PDF?

Hi,

We have recently been adding files as attachments to PDFs and I have been asked is there a maximum limit that can be added?

This could be either:

- maximum number of attachments

- maximum file size per attachment

- maximum total file size of all attachments

I am doing some testing and trying to find limits but wondered if anyone knew the answer to the above?

Many thanks in advance!
