Hi,

is it possible to merge 3/4 (big) files, with a lot of artboards, in a single PDF?

Thanks a lot, Gianni.

Yes, but we need more information. What do you mean by a single PDF? Do you want a multi-page PDF of the artboards or a single page PDF? Does it need to be editable? Is there a size maximum for the file?
