Markdown Viewer: Preview Markdown as HTML in Your Browser
Markdown Viewer renders Markdown as HTML in a sandboxed iframe, so you can inspect the formatted result in your browser. It uses marked with support for GFM tables and line breaks, then sanitizes the HTML with DOMPurify before rendering. Scripts are stripped from the output. Paste or drop in Markdown to see the preview.
Markdown Viewer is a browser-based Markdown to HTML viewer for developers who want to inspect formatted content without reading it as plain text. Paste or drop in Markdown and see it rendered in a sandboxed iframe. The tool uses marked to parse the input and DOMPurify to sanitize the HTML before rendering; scripts are stripped from the output.
The renderer supports GFM tables and line breaks, making it useful for checking how those Markdown elements appear in the preview. The workflow is direct: provide Markdown, inspect the rendered result, and copy any excerpt you need. There are no additional parsing options specified for the viewer.
Markdown is a lightweight format for writing structured text, while HTML is a markup format used to represent content for browsers. Viewing Markdown as HTML can make headings, tables, and other formatting easier to inspect than the source text alone. Use the viewer when you want to check the rendered appearance of a document or excerpt.
Markdown Viewer runs entirely in your browser. Your input is processed on your own device and is not uploaded, stored, or sent to a server. Once the page has loaded, the viewer works offline without a server dependency.
This tool can help developers and DevOps engineers review documentation, inspect Markdown they did not write, and check content before using it in a workflow. It is also useful for anyone who wants a quick rendered preview of Markdown with GFM tables and line-break support.
Step 1: Paste or drop your Markdown into the viewer. You can use a document or a shorter excerpt.
Step 2: Review the rendered result in the sandboxed iframe. Markdown is parsed with GFM table and line-break support.
Step 3: Check that the formatting matches what you expect, including tables and line breaks.
Step 4: Copy any excerpt you need from your document.
Use case: Inspect a Markdown document you did not write and find it difficult to read as plain text. The rendered view makes its formatting easier to review.
