multibackground
Use multiple pages as backgrounds
Usage
pdftl
<input>multibackground<background_pdf>[<page_spec>...][layer_name<name>]output<file>
Details
Underlay pages from the background PDF behind the corresponding pages in the input PDF: page 1 is placed behind page 1 of the input, etc.
If no page specs are given, the operation applies to all pages. Page specs use the same syntax as rotate and cat — see pdftl help page_specs.
Note: If the overlay/background PDF contains its own internal layers (OCGs), they will be flattened and merged into the page content. Individual toggleability of the source’s internal layers is not preserved.
Examples

pdftl in.pdf multibackground bgs.pdf output out.pdf
Apply multi-page background to pages 1, 3, and 5 only
