MarkdownLab

Markdown Live Preview

A split-screen Markdown editor built around one thing: watching your text turn into formatted output the instant you write it, with both panes scrolling together.

Runs entirely in your browser — files never leave your device.

How it works

  1. 01Type or paste Markdown into the left pane.
  2. 02The preview on the right re-renders automatically about 150ms after you stop typing.
  3. 03Scroll either pane — the other scrolls proportionally to keep the same section in view.
  4. 04Copy the rendered HTML, or use Download As to export Markdown, PDF, HTML, Word, RTF, or plain text when you're done.

Frequently asked questions

How live is 'live'? Is there a delay?

The preview updates about 150ms after you stop typing — quick enough to feel instant, while avoiding re-rendering on every single keystroke.

Do the two panes stay in sync when I scroll?

Yes. Scrolling either pane moves the other by the same proportion of its total scrollable height, so a long document stays roughly aligned between source and preview.

Does this require installing a Markdown plugin or extension?

No. It's a plain web page — no browser extension, no editor plugin, and no account. It works the same in any modern browser.

Is my writing saved if I accidentally close the tab?

Yes, it autosaves to this browser's local storage as you type, and offers to restore it (with a dismissible notice) the next time you open this page.

Is this the same as the Markdown Editor page?

It's the same underlying surface, positioned differently: this page is tuned for watching live rendering while you write, while the Markdown Editor page is the general-purpose writing layout.
