GUIDE / FAQ

How to use Markdown Preview

Preview Markdown with headings, lists, tables, fenced code, and GitHub Flavored Markdown support.

How to use it

  1. Type Markdown or choose a .md file.
  2. Review the safe live preview.
  3. Edit the syntax until the result is correct.

Compatibility and privacy

Output passes through an HTML sanitizer. Remote images are blocked by default so preview does not leak an IP address, referrer, or tracking parameters to third parties.

Documents stay in browser memory and are never uploaded.

Frequently asked questions

Is inline HTML supported?

Safe basic HTML may remain; scripts, iframes, forms, event attributes, and dangerous URLs are removed.

Why did a remote image not load?

For privacy, preview does not automatically connect to third-party image servers.
