I have a PDF with 7 pages. The first is a table of contents and the 6 following pages are 6 maps with the same map excerpt. The PDF does not contain geolocation. I want to georeference page 2-6 but I can only access page 1 when loading the document in QGIS.

    Use a pdf program to split out the pages., or perhaps do that indirectly by printing each page to its own pdf. Adobe offers an online tool to split pdfs as well.

If you drag&drop a multipage PDF into QGIS 3.40.x map canvas, a page selection dialog opens.

enter image description here

As you can see in the dialog, you only have to add a prefix to your datasource to load a specific page (i.e. PDF:2:d:/MyTest.pdf).

To load a specific page into Georeferencer, simply drag and drop the original PDF from File Explorer or similar into your Georeferencer map area and then change the layer source in the Georeferencer window (Settings > Source Properties...) by adding the relevant prefix (e.g., PDF:2:)

    This is a nifty trick, being able to load other pages in Georeferencer! However, when running the actual transformation from the Georeferencer UI it reverts back to processing the first page (QGIS 3.40.0). I don't think the underlying GDAL command has interpreted the layer source change. It does work if you select Generate GDAL Script and manually edit the first file reference (gdal_translate -of ... -gcp ... "D:/MyTest.pdf" -> "PDF:2:D:/MyTest.pdf") then run it in Command Line

    @she_weeds one more reason to try out the Georeferencer Extension plugin, which can handle these URIs.

I'll add this as an option to the other answer, as suggested. Use a pdf program to split out the pages to individual pdfs or jpgs. Or perhaps do that indirectly by printing each page to its own pdf. Adobe offers an online tool to split pdfs as well.

  • Under Windows I can recommend the free tool PDFTK Builder to split the pages.
