Free Windows app for viewing and editing Markdown (.md) with a live preview. Export to PDF, PNG, HTML, Word, or plain text.
From Releases, download:
| File | Notes |
|---|---|
MarkdownThing_Setup_1.2.0.zip |
Extract and run setup (~55 MB). Optional .md file association. |
MarkdownThing_Portable_1.2.0.zip |
Unzip and run MarkdownThing.exe — no install (~77 MB). |
Requirements: Windows 10 or 11 (64-bit). WebView2 for the preview (usually already installed). The first PDF or PNG export downloads a one-time component (~150 MB) so output matches the preview.
SmartScreen: The installer is not code-signed; Windows may warn about an unknown publisher. Use More info → Run anyway, or the portable zip.
- Live edit + preview; themes and optional dark mode
- Export PDF, PNG, HTML, Word (
.docx), or text (PDF/PNG match the preview) - PDF page setup, batch folder export, drag-and-drop, recent files
- Tables, task lists, code blocks, footnotes, and other common Markdown (via Markdig)
Word export covers headings, lists, emphasis, quotes, code, and links; some complex elements (e.g. tables) may not transfer fully to Word.
