Overview
Markdown is a lightweight, plain-text formatting syntax that turns simple symbols into structured documents. For example, # Title becomes a heading, **bold** becomes emphasized text, and - item becomes a list. Because it is just readable text, Markdown is widely used for READMEs, documentation, notes, and content authoring.
HTML is the markup language browsers actually render. A Markdown to HTML converter translates that plain-text syntax into real HTML tags — turning **bold** into <strong>bold</strong> and # Title into <h1>Title</h1> — so you can publish or embed the result on a web page.
This tool performs a one-way conversion from Markdown to HTML using the popular marked parser. It supports GitHub Flavored Markdown (GFM), including tables, fenced code blocks, and task lists. A Line breaks option lets you toggle GFM single-newline line breaks, so a single Enter can become a <br> when you need it.
You get two outputs at once: the generated HTML source that you can copy into your project, and a live Preview that shows how the rendered page will look. Everything runs locally in your browser — your Markdown is never uploaded to a server.
How to use the Markdown to HTML Converter
- Paste or type your Markdown into the input editor on the left.
- Toggle the Line breaks option if you want single newlines to render as HTML line breaks (GFM style).
- Watch the converter generate HTML and update the live Preview instantly as you type.
- Read the rendered Preview to confirm the output looks the way you expect.
- Copy the generated HTML source to use it in your own web page or project.
Good to know
A few things worth knowing about this converter:
- It is a one-way tool — Markdown goes in, HTML comes out. It does not convert HTML back to Markdown.
- Any raw inline HTML you include in your Markdown is passed straight through to the output. This is standard for Markdown tools, but it means you should only convert content you trust and review the result before publishing.
- Conversion is powered by the
markedparser and runs locally in your browser, so nothing you paste is uploaded.
Private by design
Every byte you paste into the Markdown to HTML Converter is processed locally in your browser. Formatly makes no network request with your data, logs nothing, and stores nothing on any server — so it is safe for API responses, tokens, configuration and other sensitive content. Your most recent input and theme are saved only in your own browser's local storage.
Markdown to HTML Converter FAQ
Is my Markdown uploaded to a server?
No. This converter runs entirely in your browser using the marked parser. Your Markdown is processed locally on your device and is never sent to or stored on any server.
Does this tool work offline?
Yes. Once the page has loaded in your browser, the conversion happens client-side, so it continues to work even without an active internet connection.
What is the difference between the HTML source and the Preview?
The HTML source is the raw <tag> markup generated from your Markdown — the text you copy into a project. The Preview renders that same HTML so you can see how it actually looks in a browser.
Can it convert HTML back into Markdown?
No. This is a one-way converter that translates Markdown into HTML only. It does not perform the reverse HTML-to-Markdown conversion.
What does the Line breaks option do?
It toggles GFM single-newline line breaks. When enabled, a single newline in your Markdown becomes an HTML <br>. When disabled, single newlines are treated as part of the same paragraph, following standard Markdown behavior.
Does it support GitHub Flavored Markdown?
Yes. The tool uses the marked parser with GFM enabled, so features like tables, fenced code blocks, strikethrough, and task lists are converted as expected.
What happens to raw HTML inside my Markdown?
Raw inline HTML written in your Markdown is passed through into the output, which is standard Markdown behavior. The converter does not strip or sanitize it, so only convert content you trust.
