Frequently Asked Questions
Calibre generates a PDF by converting the AZW3's reflowable layout to a fixed-page format. Page breaks, font sizes, and margins are recalculated. The result may differ from the Kindle rendering, especially for complex layouts.
ChangeThisFile uses Calibre's default settings for PDF output. For custom page sizes, margins, or font settings, you can install Calibre locally and use ebook-convert with custom output parameters.
Calibre includes the table of contents as PDF bookmarks in most cases. However, the exact output depends on how the original AZW3 file was structured.
