Hello,
In Indesign, if I open a multipage PDF, is it possible to remove its background (by using Indesign only) ?
In that case, I would like to remove this yellow background :

Image processing is the way to go, but here you might fake it using SCREEN blending mode on a BLACK background.
Simple demo script:
(function( orig, dup,g)
//----------------------------------
// Assuming a simple image container is selected on the page.
{
// 1. Basic enhancer.
(orig=app.selection[0]).properties =
{
strokeColor: "Black",
transparencySettings: {blendingSettings:{blendMode:+BlendMode.SCREEN}},
};
with( dup=orig.duplicate() )
{

You mean posted by the OP in Acrobat forum - using exactly the same image?

Interesting solution using layers & Effects, good example of thinking outside the box.

Thanks.
But I'm not sure if it will print correctly... Acrobat is able to display it - but PS CS6 64bit - can't raster it correctly...
In fact, I have not Photoshop to do the job. [...]

So you have InDesign but not the whole Adobe CC?
It is possible to do it in InDesign:
No external software has been used.
Good job

Attached is IDML file and PDF - INDD is 61MB - as Image is embedded.
There are multiple copies of the original image - placed on top of each other:
The bottom Rectangle - is filled with "[Black]" color and Transparency set as:
Each copy of the image - Transparency:

Ah, that is HIDING the colour background, not removing it 😉

Hiding / removing - who cares, as long as it's "not visible" 😉

The biggest bonus - no need to waste time on editing AND you keep the original intact - just place, apply ObjectStyle, duplicate few times, done - easy to automate with my tool - either on a current selection or multiple links already placed or when placing from a folder.
That's certainly clever, but the results from converting to grayscale and adding a levels layer in Photoshop are far superior, in my opinion. You've lost a fair number of edge pixels and hairline segments, and it's still in color so printing is gioing to be less crisp.

Yes, you are right, doing it - in Photoshop or something like that - is the only correct way.
I send you the original PDF file in order you could have the best quality file.

Sorry for no reply.
I think @Marc Autret's reply is spot on and you should go with it.
