How can I export a PDF from GIMP with each layer on a new page?

I have multiple layers open in GIMP. I would like to export a pdf that has each layer on a new page.

Solution 1:

Gimp (2.10) does it already. No extra software or plugins needed.

1. Import all images/pages as layers.
2. Go to File → Export As → filename.pdf.
3. After clicking Export As, a dialog will pop up asking to confirm save options. Select Layers as pages and Reverse the pages order.
4. Click the Export button.

That's all! Enjoy.

Solution 2:

GIMP (prior to 2.10) can't do this directly.

You need to use an intermediate file format.

Prerequisites

sudo apt-get install imagemagick

Steps

1. Export from GIMP as an MNG animation: File → Export → document.mng

2. Convert to PDF on the terminal:

   convert -reverse document.mng document.pdf
