I apologize in advance if I have simply missed the release note item that calls this out, but I needed to downgrade to 6.14.1 from 7.12.0 today because Apple told me that my image files in the generated ePub were too big.

Example: image1:
7.12.0: 4.49 Mb 2664 x 2991
6.14.1: 99.4 Kb 749 x 842

I first tried use the lossless approach and manipulate the ePub from the Calibre tools menu, but the overall dimensions of the image was still too big, even though the size of the image files was reduced.

So I opted to downgrade to 6.14.1 and that solved the problem.

So I would like to know if there is a specific configuration change that I can make in newer versions, specifically 7.12.0 at the moment, which will perform the same image conversion that I am used to seeing in version 6.14.1.

The source document is a docx in both cases and I was able to test on both Windows 10 and Windows 11 to know that this is not an OS issue. In both cases the MS Word document is configured to preserve images at 220 dpi and the source file is the same in both cases, just to be clear.

For now I have "solved" my issue, but I would like to know that at some point I will be able to upgrade to newer versions of Calibre.

Thank you for your help and insights!
I use calibre's editor to resize (small if too large) and recompress the cover as I want. You can do the same thing and have your images be the correct size.
