Suddenly when I download a Google Doc as a PDF, the image PNGs come down with a black background. They used to be transparent. What has happened here? Can I change it back?
This is a known bug (https://productforums.google.com/forum/#!topic/docs/0FQWIziLhAQ) To workaround the problem you can try to print the document, and choose to save it as PDF. This will make your images look right in your PDF.
Having the same issue while not having changed anything to the document I'm trying to convert since the 14th of this month. It does indeed seem limited to png files. I'm going to assume this is just a temporary thing, and will be fixed in a timely fashion.
For the time being you could export a .docx version and convert that to a pdf locally.
From what I gather, this new issue is related only to exporting docs to PDFs which have embedded PNG images with transparent backgrounds.
The documents I wanted to export all had a white background, so I solved the problem by replacing the transparent background PNG files with ones that have a white background.
Now, in September 2020 this is still a problem.
I found two workarounds for this.
- Open the PDF in OS X Preview.
- Export the PDF and use the
Reduce File SizeQuartz filter.
The new PDF is fixed and transparency will not be printed in black anymore.
Convert the PDF into
