'ImageMagick convert adds whitespace when converting PDF to PNG

I'm using ImageMagick to convert the following PDF to an PNG file.

Click here to download the PDF from IMSLP (Permalink if the direct download is broken)

In a PDF viewer it looks nice:

but when converting with convert -density 300 -background white -alpha off -alpha remove file.pdf /tmp/file.png

the image gets a large white margin:

I do not want to trim the image afterwards, I just want ImageMagick to somehow respect the view-port or however that viewing information is being encoded in the PDF. Does anyone know which command-line parameter might enable this behavior?

Edit 10.03.2022: I'm using ImageMagick 7.1.0.16 with Ghostscript 9.55.0 inside an Alpine Linux docker image.

The hint from KenS was exactly what I was looking for - the PDF defines a CropBox that ImageMagick 7.1.0 was not using by default. The solution therefore is to modify the command to include the following -define information:

convert -define pdf:use-cropbox=true file.pdf /tmp/file.png

Thank you all for your help!

I do not get your extra margin in ImageMagick 6.9.12-42 using Ghostscript 9.54. But changing the density does not seem to have any effect.

convert -density 300 -background white file.pdf[1] x2.png

The issues may be a malformed PDF. How was it created? Also what version of Ghostscript are you using? It could be a GS version issue.

If this was a scanned PDF that is a raster image in a vector PDF shell, then you could just use pdfimages to extract the raster files. See https://manpages.debian.org/testing/poppler-utils/pdfimages.1.en.html
