Download · Web version · Live site

• Live preview — see your formatted document as you type
• Mermaid diagrams — flowcharts, sequence diagrams, ER diagrams, Gantt charts, and more — render correctly in both preview and PDF
• Style sidebar — set font family, font size, line height, margins, and header/footer text. Settings persist between sessions.
• Format toolbar — select text and apply bold, italic, underline, strikethrough, text color, highlight, font family, font size
• Diagram inserter — pick a Mermaid diagram type, a template inserts at cursor
• Open file — native OS file dialog to open any .md file
• Recent files — collapsible panel shows your last 10 opened files; click any chip to reopen instantly
• Drag & drop — drop a .md file onto the editor pane to load it; dropped files are added to recents
• No Puppeteer — PDF export uses Electron's built-in Chromium (webContents.printToPDF()). No second Chromium download, no extra install.
• Offline, no server — runs as a desktop app. No Docker, no cloud dependency.

Requires Node.js 20+.

git clone https://github.com/ibrahimokdadov/winmdPDF.git
cd winmdPDF
npm install
npm run dev        # starts Next.js + Electron together

npm run build      # Next.js static export + compile Electron TypeScript
npm run dist       # packages installer for current platform

npm test           # runs Electron unit tests (Jest + ts-jest)

renderer/          Next.js 14 app (static export → renderer/out/)
electron/
  main.ts          BrowserWindow, app:// protocol handler, IPC
  preload.ts       contextBridge → window.electronAPI
  pdf.ts           webContents.printToPDF() + OS save dialog

The renderer runs as a static site served via a custom app:// protocol (not file://, which breaks Next.js absolute asset paths). PDF export flows through IPC: the renderer calls window.electronAPI.exportPDF(markdown, settings), the main process opens a hidden BrowserWindow, polls until Mermaid SVGs finish rendering, then calls printToPDF.

The original web app (with Puppeteer-based export) is at mdpdf.whhite.com and github.com/ibrahimokdadov/mdPDF.
