# `multibackground`
Use multiple pages as backgrounds
## Usage
> pdftl `` `multibackground` `` `[...]` `[layer_name` `]` `output` ``
## 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
> Multi-page background
```
pdftl in.pdf multibackground bgs.pdf output out.pdf
```
> Apply multi-page background to pages 1, 3, and 5 only
```
pdftl in.pdf multibackground bgs.pdf 1,3,5 output out.pdf
```
