How to use Markdown Preview

  1. Write or paste Markdown in the left box (or open a .md file).

  2. See the preview on the right; on a phone, switch between the Write and Preview tabs.

  3. Copy the HTML, or download it as a standalone .html document or a .md file.

Supported syntax

It supports standard Markdown and the GitHub (GFM) extensions: headings (# to ######), **bold**, *italic*, ~~strikethrough~~, links and images, ordered and unordered lists, task lists (- [x]), quotes (>), fenced code blocks with a language, inline code, horizontal rules and tables. The Line breaks become <br> option mimics the style of GitHub comments.

HTML safety

Markdown can embed raw HTML, and that is a common route for XSS attacks. That is why the output is sanitized by DOMPurify before it is shown: scripts, event attributes (onclick, onerror) and javascript: links are removed. You can also turn raw HTML off so tags are shown as text. Links to outside sites open in a new tab with rel noopener.

Images from web addresses are loaded directly by your browser from the owner’s site, so the owner of that site can see your IP address. The Markdown text itself is not sent to a server.

Questions about Markdown Preview

What is Markdown?

A lightweight writing language that is converted to HTML. For example, # Title becomes a large heading and **word** becomes bold. It is widely used on GitHub, in documentation and on blogs.

How do I make a table in Markdown?

Write a header row separated by pipes, a divider row made of dashes, then the data rows: | Name | Age | then |------|------| then | Sam | 30 |.

Is HTML inside Markdown executed?

Safe tags such as <br> or <details> are shown, but scripts and dangerous attributes are removed by the sanitizer. Turn off the raw HTML option to show every tag as text.

Is my writing sent to a server?

No. Markdown is processed in your browser and is not stored.
