About this extension
MD Capture lets you pick any element on a webpage — a paragraph, a table, an article, even an entire section — and turn it into clean Markdown with a few keystrokes. No more copy-pasting into online converters or hand-writing markup.


Enter capture mode and move through the DOM hierarchy with your keyboard:
- ↑ / k — parent · ↓ / j — first child · ← / h — previous sibling · → / l — next sibling
- Enter — confirm and exit · Shift+Enter — confirm and keep capturing (multiple elements)
- Esc — exit · ? — bring back the floating panel
- When selecting whole page, asks for confirmation before converting the whole page


Prefer the mouse? Toggle the crosshair button in the panel: hover to highlight, click to lock — just like the browser's element picker.
  • Highlighted element with a floating tag (tag, id, class) that follows scrolling
  • A floating panel (draggable & resizable, remembers position/size) showing:
  • a canvas thumbnail of all block-level elements drawn in document coordinates (doesn't shift when you scroll)
  • breadcrumb path, tag / id / class, size, child count, empty state
  • Keep or strip images, links, tables, code blocks
  • Clean inline styles (unwrap span/font), remove empty paragraphs
  • Heading style: keep original level / flatten to bold / force H2
  • Local CSS filter: pick a parent element, then extract only the nodes matching your selector (e.g. article p, .content img)


Markdown is copied to the clipboard automatically with a toast notification, followed by a floating action bar (8s): Open Preview (raw source in a new tab) and Download .md.
  • Toolbar icon → popup (quick toggles) → Start Capture
  • Right-click anywhere → "Capture element as Markdown" (starts from the element under the cursor)
  • Shortcut: Ctrl+Shift+M (reassignable in about:addons)


Everything runs locally in your browser. No data is collected, stored remotely, or sent anywhere. Permissions are minimal: activeTab (current page only), contextMenus (context menu entry), clipboardWrite (copy result), storage (save your settings).

Interface languages: English, 中文.
