Introduction

Markdown Preview Enhanced is an extension that provides you with many useful functionalities such as automatic scroll sync, math typesetting, mermaid, PlantUML, WebSequenceDiagrams, pandoc, PDF export, code chunk, presentation writer, etc. A lot of its ideas are inspired by Markdown Preview Plus and RStudio Markdown.

Feel free to ask questions, post issues, submit pull request, and request new features.

Privacy

This extension does not collect, transmit, or share your data with any external service. The core preview, scroll sync, math typesetting, diagram rendering, and all editor features run entirely on your local machine. No telemetry, no tracking, no phone-home.

• Markdown content — rendered locally; never leaves your machine.
• Math (KaTeX/MathJax) — typeset locally or via a CDN JavaScript library you configure (default: jsdelivr).
• Diagrams (Mermaid, Graphviz, Vega, WaveDrom, D2, TikZ) — rendered locally using bundled or system-installed tools.
• PlantUML — rendered via your own PlantUML server (plantumlServer config) or a local .jar file. Unless explicitly configured to use kroki.io, no diagram data is sent to any remote service.
• Image upload (imgur, sm.ms, qiniu) — opt-in only. Requires you to manually trigger the upload and configure API credentials.
• Pandoc / ebook / PDF export — uses locally installed tools; no data is uploaded.

If you have any questions about data handling, please open an issue.
