Converter

Markdown to HTML

Render Markdown to HTML with Marked entirely in your browser — the same local-first model as APK Analyzer and APK String Extractor: your source text is not uploaded to DroidXP. The Marked bundle loads from jsDelivr. Reverse direction: HTML to Markdown. Live Markdown preview: Markdown Previewer.

What this tool does

Marked tokenizes your Markdown and emits HTML strings. Toggle GFM for GitHub-style extras Marked supports, and hard line breaks when you want single newlines to matter inside paragraphs.

Local vs CDN

Your Markdown is not uploaded for rendering — parsing happens in the tab. The Marked file is fetched from jsDelivr when you load this page, which is standard for static libraries.

Privacy

Output and checkboxes may persist until you clear the page; options can be saved in localStorage. Do not rely on the preview iframe as a complete security boundary for hostile content — always sanitize before production use.

How to use this tool

  1. Step 1: Paste Markdown or upload .md / text; tune GFM and hard line breaks if needed.
  2. Step 2: Click Convert; optionally enable the sandboxed preview to eyeball formatting.
  3. Step 3: Copy HTML or download a .html file; sanitize before publishing.

Frequently Asked Questions

Does DroidXP upload my Markdown or HTML?

No. Marked runs in your browser on the Markdown you provide. It is not sent to DroidXP servers for conversion. The Marked script loads from jsDelivr like a normal script tag.

Is the generated HTML safe to publish as-is?

Markdown can include raw HTML blocks, which may contain scripts or event handlers. Marked does not sanitize output. Sanitize before putting HTML on a live site (e.g., with a trusted HTML sanitizer in your pipeline).

What does enabling GFM do?

It turns on GitHub-flavored Markdown features Marked supports in this mode (such as tables and strikethrough-style syntax). Exact behavior follows Marked’s parser — edge cases may still need tweaking.

What does “hard line breaks” mean?

When enabled, single newlines in paragraphs can produce line breaks in the HTML output (like GitHub’s rendering). When off, paragraphs usually flow until a blank line.

Does the sandboxed preview run my scripts?

The optional preview uses an iframe with a restrictive sandbox so embedded scripts should not execute there — use the preview as a rough visual check, not a security guarantee for arbitrary untrusted Markdown.

Large documents?

Very large Markdown can slow parsing in the tab. Use CLIs or build steps for huge content; this page targets articles, READMEs, and snippets.

Same privacy idea as APK Analyzer?

Yes for content: your Markdown stays local during conversion. Only page assets (HTML/CSS/JS, including Marked from the CDN) load over the network — not your document text for processing.

Will HTML round-trip back to the same Markdown?

No. Converting HTML back to Markdown with another tool is lossy. Use this page as Markdown → HTML only.

Why does my table or list render oddly?

Check indentation, blank lines around lists, and GFM toggles. Parsers are picky about spacing; simplify the source and convert again.

Can I use this for CMS or email HTML?

You can copy HTML into those systems, but you still need sanitization, asset URLs, and template rules appropriate to each platform.

Is this a substitute for static site generators?

No — generators add templates, linking, and builds. This tool is for quick one-off Markdown rendering and inspection.
