Publishing guides for designed books

Everything you need to take a PDF from Canva, InDesign, or Affinity Publisher to a store-ready EPUB — format choice, fonts, images, metadata, device testing, and what to do when a conversion doesn't pass.

From PDF to Published EPUB: The Complete Workflow — every stage of what actually happens to your PDF.

Fixed-Layout EPUB — how it works, Amazon KDP requirements, and converting your designed PDF without losing a pixel.
Reflowable EPUB — when to use it instead of fixed-layout, why there's no image layer between text and assistive technology, and retailer compatibility.
PDF Preparation — export settings, fonts, transparency, page dimensions, and file size limits by plan.
Fonts — the Sovereign Six font stack, auto-mapping, and per-page overrides.
Images and Accessibility — image handling, AI alt-text generation, and accessibility metadata by mode.
Metadata, ISBN, and TOC — book metadata, ISBN, and table-of-contents generation.
Device and Testing Checklist — a pre-publish checklist across 17 real e-readers, tablets, and phones.
