Converting HTML to Markdown comes up when you migrate a CMS, scrape documentation, or clean up email and web exports for a Git-based workflow. A good tool preserves headings, lists, links, tables, and fenced code without drowning you in extra markup. Watch for URL fetching (paste a page link instead of raw HTML), GFM compatibility, and whether you pay per seat or page.
Also check privacy: browser-based converters keep processing on your machine for pasted HTML, while “fetch URL” features call a server to retrieve remote pages—fine for public docs, risky for intranet HTML. For regulated content, prefer local CLI tools or in-house scripts.
Here are solid options—listed roughly in order of how often teams reach for them for day-to-day cleanup and migration work.
Limitations: It is browser-based, so very large documents are better split into chunks; complex, highly styled layouts may still need a manual pass like any converter.
If you already use Paste to Markdown for clipboard content, pair it with the HTML tool when you have a full page or export file—the pipelines overlap but target slightly different inputs.
Limitations: Setup and flags have a learning curve; it is not “open a tab and go” for occasional one-offs.
Typical one-liners look like
Limitations: You integrate and maintain code—not a turnkey UI for non-developers.
Teams often wrap Turndown in a small internal web form so writers get a consistent rule set without installing Pandoc.
Limitations: Philosophy is “good enough for downstream models,” not always pixel-perfect GitHub-flavored tables for human editors—verify output for publishing use cases.
It shines when HTML is one input among PDFs, DOCX, and other office formats in an automation pipeline.
Limitations: Free tiers are capped; sensitive content may not belong on a third-party server—check privacy and retention policies.
API-based converters are useful when marketing or support teams submit tickets and you want Markdown artifacts dropped into a repo automatically—just budget for quotas and error handling.
Bottom line: For fast, free conversions with URL fetch and solid table support in the browser, start with [SiteSupport’s HTML to Markdown converter](/tools/html-to-markdown). Reach for Pandoc or Turndown when you need automation at scale or custom rules inside your own stack. Whichever you pick, spot-check tables and code blocks first—they are where most lossy conversions show their seams.

1. SiteSupport HTML to Markdown Converter
The [SiteSupport HTML to Markdown converter](/tools/html-to-markdown) is a free, no-signup web tool aimed at quick, repeatable conversions. You can paste raw HTML or fetch from a URL, which saves time when you are converting live pages or CMS exports. It handles common structures—headings, lists, tables, links, images, inline and block code, blockquotes—and outputs clean Markdown suitable for READMEs, static sites, and wikis.Limitations: It is browser-based, so very large documents are better split into chunks; complex, highly styled layouts may still need a manual pass like any converter.
If you already use Paste to Markdown for clipboard content, pair it with the HTML tool when you have a full page or export file—the pipelines overlap but target slightly different inputs.
2. Pandoc
Pandoc is the heavyweight CLI Swiss Army knife: HTML in, Markdown (and many other formats) out, with deep options for filters and templates. It excels in scripted migrations and CI pipelines where you need repeatable, versioned conversions.Limitations: Setup and flags have a learning curve; it is not “open a tab and go” for occasional one-offs.
Typical one-liners look like
pandoc -f html -t markdown_strict or GFM-flavored variants—read the docs for the flavor that matches your destination (GitHub vs generic CommonMark).3. Turndown (JavaScript library)
Turndown is the standard in-app HTML→Markdown engine for many products. If you are building an internal tool or a static pipeline in Node, you get fine-grained control over rules (e.g. how tables or spans map).Limitations: You integrate and maintain code—not a turnkey UI for non-developers.
Teams often wrap Turndown in a small internal web form so writers get a consistent rule set without installing Pandoc.
4. MarkItDown (Microsoft)
MarkItDown targets turning assorted file and HTML-like inputs into Markdown-ish text for LLM and doc workflows. Useful when HTML is one of several formats in a larger automation story.Limitations: Philosophy is “good enough for downstream models,” not always pixel-perfect GitHub-flavored tables for human editors—verify output for publishing use cases.
