I had this case a while ago: a magazine in AZW3 format that, when converted to PDF, would result in images compressed and reduced, no matter what I would change in the HTML or the conversion settings. I just wanted uncompressed and full-size images.

HTML looked like this for each image:

<body><div class="class-0-7" id="id-0-7"><div class="class-0-8" id="id-0-8"><img class="class-0-9" id="id-0-9" src="../images/00003.jpeg" width="2386" height="3142"/></div></div>

What eventually worked was extracting all images to a folder, creating a ZIP archive with them - I had luck that their filenames were numerically ordered. Then I renamed it to CBZ and was able to convert this file to PDF without any compression or image resizing.

In this case, I had to disable comic processing in Calibre CBZ input conversion dialog.

edit: I don't know if CBZ or PDF are available on the Libra but... just a random idea.
