Markdown Editor

A clean Markdown editor that runs entirely locally: write on the left, live preview on the right, import and export .md, export HTML, and drafts are saved automatically in your browser. A dedicated "Article / HTML to Markdown" section lets you paste web article content or HTML source and convert it to Markdown.

A Markdown editor with writing on the left and live preview on the right, which also converts web articles or HTML into Markdown. It runs entirely locally in your browser. This guide explains common syntax and conversion.

What is Markdown?

Markdown describes formatting with a small set of symbols, letting plain text express structure such as headings, lists, and links. It is easy to read and write, widely used in documentation, blogs, and README files.

For example, # marks a heading, **text** marks bold, and - marks a list item, while the source text itself stays clearly readable.

Live preview

While you type on the left, the right side renders the final look instantly, with no manual refresh.

Preview rendering is sanitized first: even if the content contains raw HTML, dangerous tags such as scripts are filtered out to prevent XSS.

Import and export

"Import .md" loads an existing Markdown file so you can keep editing.

Export .md: save as a plain-text Markdown source file
Export HTML: generate a complete web page that opens directly in the browser
Copy HTML: copy only the rendered HTML fragment, easy to paste into an existing page

Article / HTML to Markdown

Besides writing Markdown by hand, you can convert existing web articles or HTML code into Markdown, saving the effort of formatting manually.

Paste rich text: copy the body from a web page or document and paste it in, keeping structure such as headings, lists, tables, and links
HTML source: paste source code such as <h1>, <p>, <table>, or upload an .html file
After conversion you can copy, download the .md, or send it into the editor with one click to keep editing

Where are drafts saved?

Your input is automatically saved in the localStorage of your local browser, so you can keep editing after a refresh or the next time you open it.

Drafts exist only on your own device and are never synced or uploaded to any server. Clearing browser data also clears the drafts.

FAQ

Will my written content be uploaded?

No. Markdown parsing and preview happen entirely locally in your browser. Content is never sent to any server.

Where are drafts stored?

They are stored in the localStorage of your local browser, visible only on this device, never synced or uploaded.

Can it be exported as a web page?

Yes. Clicking "Export HTML" generates a complete HTML file with basic styling, which opens in the browser by double-clicking.

Are tables and code blocks supported?

Yes. The editor uses GFM (GitHub Flavored Markdown) syntax, so tables, task lists, fenced code blocks, and more all render correctly.

How to convert a web article into Markdown?

Switch to "Article / HTML to Markdown", paste the article body directly on the left, or paste HTML source / upload an .html file. Markdown is generated automatically on the right, ready to copy, download, or send into the editor.

Does conversion keep tables and links?

Yes. Conversion follows GFM rules, and structure such as headings, lists, links, tables, strikethrough, and task lists is preserved as much as possible.
