Markdown ↔ HTML Converter - Free, Online, Local
What is a Markdown ↔ HTML converter?
This tool turns Markdown into HTML or HTML back into Markdown so you can move content between docs, CMSs, and email without hand-editing tags. It runs in your browser, so drafts stay private.
How to use the converter
- Choose direction: Select “Markdown → HTML” or “HTML → Markdown.”
- Paste content: Drop your Markdown or HTML into the main box.
- Sanitize (optional): Leave sanitization on to strip scripts/iframes/style tags from pasted HTML.
- Copy output: Grab the converted result and paste it into your CMS, editor, or email.
Why use this converter?
- Fast round-trips: Swap formats in one click instead of manual find/replace.
- Safer HTML: Optional sanitization removes risky tags from unknown sources.
- Offline-friendly: All processing stays in your browser; no uploads.
Use case 1: CMS import
Draft in Markdown, convert to HTML, and paste into a WYSIWYG that expects tags.
Use case 2: Email cleanup
Strip risky tags from pasted HTML before sending to a mailing platform.
Use case 3: Docs round-trip
Copy HTML snippets from design handoffs, convert to Markdown, and drop into your repo.
Examples
Basic example (Markdown → HTML)
Input:
# Title
**Bold** and *italic* with a [link](https://textavia.com).
Output: <h1>Title</h1><p><strong>Bold</strong> and <em>italic</em> with a <a href="https://textavia.com">link</a>.</p>
HTML → Markdown
Input: <h2>Subhead</h2><p>Paragraph with <strong>bold</strong> text.</p>
Output:
## Subhead
Paragraph with **bold** text.
Common errors
Script/style tags still present
Turn on “Strip scripts/iframe/object” to remove them before conversion.
Lists collapsing
If a pasted list was malformed HTML, fix the source first; this converter assumes valid list tags.
Tips and proven approaches
- Keep links clean: convert, then run URLs through the URL encoder if you add parameters.
- For long docs, convert section by section to keep context clear.
- If you see double line breaks in Markdown, trim trailing spaces in the source HTML.
