How do convert an image to pdf so it opens in viewable zoom level?

I've experimented a bit with img2pdf on macos, I can't find a parameter to run it to convert a high res jpg file to a pdf that creates a pdf that doesn't open super zoomed in without any additional changes.

Running img2pdf with --pagesize A4 --fit works, the output pdf is viewable from the start - but it also has a layer of white background on it (the part that doesn't fill the A4 format).

In my experience, neither --viewer-magnification or --viewer-fit-window have any effect on how the output pdf is opened in Preview.

Any solution?

This seems to be a duplicate of #40.

When I implemented the --viewer-magnification option I only duplicated what libre office does when exporting to PDF. In that export dialog, libre office offers to set a viewer magnification. I've done the same in img2pdf such that it produces PDFs with the same metadata as libre office does when this option is used.

But I was never able to find a PDF viewer that respects this option.

Just open-source PDF viewers, or also Adobe / Foxit / Master PDF Editor ?

Only the free software viewers. I don't think you can even install Adobe Acrobat on Linux these days (I know it was possible in the past).

Hi @plagi I'm not sure what you wanted to say with your last message. Can you rephrase? Thank you! :)

My answer:
You need to use the pdf file display setting in the viewer.
