Preview

Use cases and practical choices

Developers can preview project READMEs, support teams can draft instructions, and training or project teams can structure notes. The tool helps inspect formatting; publishing, version control and document approval remain separate workflows.

How to preview Markdown

  1. Type or paste Markdown into the source area, including headings, lists, links or code blocks. The preview updates as you type without a file upload.
  2. For a README, manual or meeting note, inspect heading levels, list indentation, tables and closing code fences.
  3. Check link and image locations. Relative paths can resolve differently here and in a repository, while external images may require network access. A local preview does not guarantee identical rendering on every platform.
  4. Retain or copy the Markdown source when finished. The page has no cloud saving, collaborative history, PDF download or standalone HTML-export button; save your work before leaving.

Markdown preview FAQ

Does this suit READMEs, product documentation and meeting notes?

It is useful for checking headings, lists, fenced code and common tables. It is a source-and-preview utility, not a complete document-management or collaboration system. Save the source in your repository, notes application or intended destination; the page does not create a project file for you.

Why does the same Markdown look different on GitHub or elsewhere?

Platforms can differ in syntax extensions, styling, image-path resolution and HTML filtering. This preview uses marked and sanitized HTML rather than replicating every platform. Check the final destination, especially relative images, embedded HTML and extension-specific features.

Will pasted HTML or scripts run directly?

Preview HTML is sanitized, so this is not an environment for executing arbitrary scripts or testing a complete website. Some tags and attributes can be removed by filtering. Use a suitable development environment when you need interactive webpage behavior.

Can I export PDF or HTML, or recover an unsaved draft?

There are no PDF or HTML file export controls, draft recovery or version history. Retain the Markdown source and publish or convert it with the intended downstream tool. If a refresh or navigation loses the draft, this page has no server-side copy to restore.
