🔍 How your file is processed

Runs: In your browser on this page
Engine: In-browser JavaScript converters with no external libraries (XML parsing uses the browser's built-in DOMParser)
Max input: 512 MB per file (or paste text directly)
Your file: Processed in this browser tab — the file is not uploaded. Converted results are kept in this browser's local storage for up to two hours so their matching download page can show them; expired results are removed on the next site visit. Nothing is stored on our servers.
Good to know: Format limits apply: nested JSON values are embedded as JSON text inside a single CSV cell (not expanded into columns), and CSV values are always imported as text — no number or boolean detection is attempted.

Why convert Markdown to HTML?

Turn READMEs, notes and drafts written in Markdown into the exact HTML browsers render: headings, lists, links, code blocks, quotes and tables. Copy the markup into your CMS, newsletter tool or website — with a live preview so you can check the result first.

What this tool preserves — and what it changes

✓ Preserved

The CommonMark core that matters — ATX headings, lists, links, images, bold/italic, inline code, fenced code blocks, blockquotes, horizontal rules — plus GFM strikethrough
GFM tables, converted to real <table> markup with thead and tbody
The code-fence language, kept as a class="language-…" attribute ready for a syntax highlighter

↺ Changed

Raw HTML inside the Markdown is escaped and shown as literal text, never passed through — tags in the source cannot reach the output markup
Two trailing spaces at a line end become a <br>, per the Markdown hard-break rule
The result is an HTML fragment (no <html>/<head> skeleton) — made to paste into an existing page, CMS or newsletter template

Known limits & edge cases

List nesting is one level deep (2-space indent), and a nested list inherits the outer list's type
Bare URLs are not auto-linked — write them as [text](url)
The paste box's live preview renders exactly the markup you copy or download, so what you check is what you ship

About the formats

What is a Markdown file?

Markdown is a lightweight way to write formatted text with plain characters: # for headings, ** for bold, - for lists. READMEs, documentation, notes apps and static site generators all speak Markdown. Converting Markdown to HTML produces the exact markup browsers render, ready to paste into a website, email template or CMS.

What is an HTML file?

HTML is the markup language of the web — the format every browser renders. Generating clean HTML from Markdown gives you ready-to-publish markup for websites, newsletters and CMS content without writing tags by hand.

From writing format to publishing format

Markdown is where text gets written — READMEs, notes, docs, drafts — but browsers, CMS fields and newsletter tools want HTML. This converter renders your Markdown to clean markup: headings, lists, links, emphasis, code blocks and tables, with no inline styles bolted on, so the output inherits whatever stylesheet the destination already has instead of fighting it.

That unstyled cleanliness is the practical point: paste the HTML into a CMS body field, an email template or a static page and it looks native immediately. It also makes the output auditable — what you see is structural markup, not a soup of spans. Write in Markdown’s frictionless syntax, convert at publish time, and keep the .md file as the editable source of truth.

Frequently asked questions

Is this Markdown to HTML converter free?

Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.

Can I convert multiple Markdown files at once?

Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.

Which Markdown syntax is supported?

Headings, bold/italic/strikethrough, links, images, inline code, fenced code blocks, blockquotes, ordered and unordered lists, horizontal rules and GitHub-style tables — the constructs used in virtually all READMEs and notes.
