Don't use an ebook as source if you are publishing on paper. You export a PDF with Amazon desired margins defined in the wordprocessor page styles.
There is then no need at all to download from Amazon, the PDF you upload is what they use. You do need to preview on screen and check that the cover works and the page trim works. They'll tell you if the margins are violated.

A PDF download is pointless for actual ebooks. You have to do a test buy of mobi, azw3 and KFX on a suitable ereader(s). Kindle preview is also a bit pointless.

On ebooks Amazon will reprocess any large jpegs and may change PNG to 256 colour indexed GIF.

jpeg = jpg, just different text for the file ending. No effect.

Only use Calibre's PDF converter to convert ebooks for you own use. Publishing on paper doesn't involve Calibre at all (only used to make ebooks). The best way is properly style pages, header, footer etc in MS Word or LO Writer and then direct export a PDF.

You only use Calibre for publishing to make an epub from a docx (which need different settings to a paper edition), or exceptionally also making a "dual Mobi" for Smashwords so they can offer epub and Kindle versions. Only upload an epub to Amazon KDP for an ebook version, which Amazon converts to mobi, azw3 and kfx.

Amazon don't convert PDFs properly formatted for paper publishing, which is the only use for a PDF in publishing.
