What Preview Mode Shows
Preview mode displays your book exactly as readers will experience it in the final exported format. It strips away the editor interface -- the block handles, hover controls, toolbar, and chapter sidebar -- and renders your content in a clean, reader-facing layout.
This means you see your text with the applied theme styling, proper font rendering, heading hierarchy, image placement, blockquote formatting, and list indentation all working together as a cohesive page. Preview mode is the closest representation of your finished book before you export.
How to Access It
Preview mode is available directly within the editor. Activate it to switch from the editing canvas to the reader view. Your content appears in a polished layout that reflects all the formatting and structural decisions you have made.
To return to editing, simply exit preview mode and you are back in the block editor with all your content exactly as you left it. Switching between editing and preview is instant -- there is no processing delay or content reloading.
Preview Reflects Your Current Theme
The preview renders your content using the theme you have selected in the Theme tab. This includes typography, spacing, color palette, and overall page layout. If you switch themes, the preview updates to reflect the new design immediately.
This makes preview mode an essential tool when choosing between themes. You can switch themes and preview the result to see which design best suits your content before committing. The combination of the Theme tab and preview mode lets you make informed design decisions without exporting test files.
Checking Formatting Before Export
Use preview mode as a final quality check before exporting your book. Walk through each chapter and look for:
- Heading consistency -- Are your H1, H2, and H3 headings used in a logical hierarchy throughout?
- Image placement -- Do images appear where you expect them, and do they complement the surrounding text?
- Blockquote styling -- Are quotations and callouts visually distinct and properly formatted?
- List formatting -- Do bullet and numbered lists render cleanly with correct indentation?
- CTA visibility -- Are call-to-action blocks prominent enough to catch the reader's eye?
- Overall flow -- Does the content read naturally from start to finish without jarring transitions?
Catching formatting issues in preview is far easier than discovering them in a PDF or EPUB after export. Make it a habit to preview each chapter before you finalize your book.
