Jpeg exported by Indesign have wrong dimensions when combined into PDF in Acrobat
A company needs to export Indesign documents in jpeg format. The jpeg files produced must be combined into a single PDF file. The problem is that the produced PDF does not maintain the original dimensions of the Indesign file.
The same files opened and saved again by Photoshop, instead, produce PDFs with correct dimensions when processed by Acrobat.
Instead of 480.00 x 330.00 mm, the file appears to have the dimensions of 1,999.99x1,374.8 mm.
It should be noted that by exporting the files in PNG format, the problem does not occur.
They required to export in JPEG format because they need CMYK color files, which will then have to go to print.
Tested on Adobe Indesign CC 2017 to Adobe Indesign CC 2020.

Interesting. I tested A5 document export do JPG and PNG, both at 300 ppi, and they both combined in Acrobat at correct A5 size. BUT, next i tried your size 480x330 mm to JPG at different resolutions, and weird thing happens when combined in Acrobat (all exported jpg files open fine in right dimensions in Photoshop):
at 72 ppi -> 480x330 mm in Acrobat
at 96 ppi -> 640x440 mm in Acrobat
at 150 ppi -> 1000,1x687,6 mm in Acrobat
at 300 ppi -> 2000x1375 mm in Acrobat
