This new tool is a companion to my older Scale Pages tool, but whereas the old tool could scale pages in the same ratio as the original, this one allows you to scale your PDF pages non-proportionally, meaning they can have whatever ratio you'd like.

For example, let's take this file I created with an image:

Original PDF file with non-scaled image (see dimensions in bottom left corner)

If we click on the tool's button on the right, this dialog will appear, allowing us to select which pages to scale, and to what new size:

The script's settings dialog

We enter the new size we want the images to have:

And then we click OK, and the document is immediately transformed:

The scaled image, notice the new page dimensions

If we wish we can do the same, but just for some of the pages:

The result (I zoomed out so you could see that only pages 1 and 3 were scaled, not 2):
