What happens to the PDF's page numbers?

Gone — MOBI is reflowable, so fixed pages dissolve into a continuous stream measured in Kindle locations. Anything that cites the PDF by page stops lining up, which matters for academic use but not for cover-to-cover reading.

How do images and diagrams from the PDF look on a Kindle?

Each image is extracted and embedded inline, scaled to the screen width and rendered in sixteen shades of gray on e-ink hardware. Fine-detail diagrams and wide tables suffer at six inches; the Kindle apps on tablets handle them better via zoom.

Should I convert myself or email the PDF with 'Convert' in the subject?

Amazon's subject-line trick reflows the PDF server-side, but you never see the result until it's on the device. Converting first lets you inspect and fix the output — and for pre-2012 Kindles that load MOBI over USB, it's the only route anyway.

Converting PDF to MOBI turns a fixed document into a reflowable ebook that resizes text to fit Kindle screens — far more comfortable to read than a zoom-and-pan PDF.
