Lossless JPEG2000 to PDF Compression, part 2

[Jalen30051005ql1u]

How do I losslessly compress lossless JPEG2000 files to pdf without losing any quality?

Another thing, my images are 96 dpi and have a resolution of 1920x1080, but when I put them in a pdf file and exported them, I had to use 72 dpi instead of 96 dpi to match/get the right resolution from the input/ How do I fix that?

JPEG2000 images stays untouched when converted in PDF with Acrobat.

96 or 72 DPI don't matter, since this is just a metadata used by page layout software (InDesign, etc.), only the size in pixels counts.

You can check it using the Output Preview.
