Markdown Editor
A distraction-free Markdown editor: type on the left, see a clean live preview on the right. Your draft autosaves to this browser as you go.
Runs entirely in your browser — files never leave your device.
How it works
- 01Start typing Markdown in the left pane, or upload an existing .md file.
- 02Watch the sanitized preview update on the right as you type — no manual refresh needed.
- 03Scroll either pane and the other follows proportionally, so you always know what you're looking at.
- 04Pick a document theme to recolor the preview, then use Download As to export Markdown, PDF, HTML, Word, RTF, or plain text — the download always matches what the preview shows.
Frequently asked questions
Does my draft get saved anywhere?
Yes, automatically, to this browser's localStorage only — nothing is uploaded to a server. If you close the tab and come back, a dismissible banner lets you know your draft was restored.
Is my Markdown ever sent anywhere?
No. Parsing, sanitizing, and rendering all happen client-side in JavaScript, and typing, editing, and previewing all work the same with your network disconnected. Two exceptions need a network connection and make direct browser requests, not a server relay: using "Open from URL" to fetch a remote file, and exporting to PDF or Word when your Markdown embeds remote images (those get fetched so they can be included in the download).
What Markdown features does the editor support?
GitHub-Flavored Markdown: headings, bold/italic/strikethrough, links, images, ordered and unordered lists, task list checkboxes, tables, blockquotes, fenced code blocks, and horizontal rules.
Can I open a Markdown file I already have?
Yes — click Upload .md to load a local .md/.markdown/.txt file's contents straight into the editor.
How do I get my writing out of the editor?
Copy HTML copies the rendered, sanitized markup for pasting elsewhere. Download As exports the current draft as Markdown, PDF, HTML, Word (also opens fine in Google Docs), RTF, or plain text — the PDF and HTML downloads use the same content and document theme colors shown in the preview, and the PDF downloads directly (no print dialog).
What does the document theme picker change?
It recolors the preview pane and the PDF/HTML downloads with one of 21 palettes (Default plus 20 named themes) — the toolbar, the Markdown source pane, and the status bar always stay on the editor's normal appearance, so switching themes never makes your own writing area harder to read.
What's the difference between this and the Markdown Viewer or Live Preview pages?
They share the same editing surface. This page is positioned for general writing; the Markdown Viewer defaults to a maximized preview for reading an existing file, and Live Preview is tuned for watching your Markdown render as you write it.
