MOBI to PDF: a format from before CSS

MOBI predates the Kindle Fire and carries a very limited subset of HTML — no real stylesheet support, tables that were approximations, images sized for screens of the era. Converting to PDF typesets that thin markup onto fixed pages. The output is usually plainer than people expect, and that is the source file rather than the conversion.

Convert when you need pages you can print or annotate. If you want the book to look good rather than just be readable, convert to EPUB or AZW3 instead and let a reader lay it out.
