FluxMarkdown can export the rendered view of any Markdown document to a PDF or a standalone HTML file. Both formats capture everything visible in the preview: rendered diagrams, syntax-highlighted code, math, images, and the active theme. Export is available in the standalone app; the QuickLook panel only renders previews and does not expose export actions.

​
PDF export

1

Open the file in the app

Double-click a .md file in Finder to open it in the FluxMarkdown app window, or press Cmd+O to open a file.
2

Trigger the export

Press Cmd+Shift+P, or choose File → Export as PDF from the menu bar.
3

Adjust the font size

A save panel opens with a font-size slider (range: 8–72 px). The slider is pre-set to the current effective visual font size — the base font size multiplied by the active page zoom. Adjust it if you want a different print size from what you see on screen.
4

Choose a destination and save

Pick a folder and filename, then click Save. FluxMarkdown generates a paginated A4 PDF using NSPrintOperation and opens the save location in Finder.

​
What the PDF includes

  • Rendered Markdown body at the font size chosen in the save panel
  • Syntax-highlighted code blocks (styles are inlined for the print context)
  • Mermaid, Vega, and Graphviz diagrams (captured as vector SVG)
  • KaTeX math expressions
  • Local images (embedded as base64 data URIs so the PDF is self-contained)
  • A4 pagination using @media print rules — code blocks and images avoid page-break splits where possible
The font-size slider default reflects your current zoom level. If you zoomed in with Cmd++ before exporting, the slider will show that zoomed size. Reset zoom with Cmd+0 before exporting if you want the base font size.

​
HTML export

1

Open the file in the app

Double-click the .md file in Finder or use Cmd+O.
2

Trigger the export

Press Cmd+Shift+E, or choose File → Export as HTML from the menu bar.
3

Choose a destination and save

A standard save panel opens. Pick a location, confirm the filename, and click Save.

​
What the HTML file includes

The exported HTML is a single, fully self-contained file — no external dependencies required:

Inlined CSS

All stylesheets (GitHub Markdown CSS, KaTeX fonts, code highlight theme, callout styles) are collected from the live document and written into a single <style> block in the <head>. The file renders identically in any browser, offline.
Local images referenced in the Markdown (PNG, JPG, GIF, SVG, WebP) are read from disk and converted to data: URIs. The exported HTML file contains every image inline — you can share it with someone who does not have the original assets.
Mermaid, Vega, and Graphviz diagrams are exported as their final SVG output, not as source code. The recipient does not need any diagram library installed.
The export captures whichever theme was active at export time (light or dark). It also includes @media (prefers-color-scheme: dark) rules so browsers that support system-level dark mode will honour the user’s OS preference.

​
Limitations

Export (Cmd+Shift+P / Cmd+Shift+E) is only available in the standalone app. The QuickLook panel that opens when you press Space in Finder does not support export — keyboard shortcuts may be intercepted by the system in QuickLook mode.To export, double-click the file to open it in the full app.
