Exporting a combined PDF (a single PDF assembled from multiple docs) is often best practice when the end-goal is to print out an export to be viewed in-hand, or shared manually. A combined PDF export can be generated from:
1. A folder.
Use the mini hamburger menu on a folder, and select “Assemble as PDF." Name your PDF export and make selections for cover and placeholder images.
2. Individual document selections.
Choose the docs for your export from a listing page. Use the top level export menu and select “As Combined PDF." Name your PDF export and make selections for cover and placeholder images.
Why Are There Multiple Volumes for Download?
Export volumes are divvied up based on the number of pages in the volume, with a maximum of 2500 pages per volume (so if one document has 2500 pages, only that document will be in the export).
