Markdown → HTML

Converts Markdown into HTML.

Markdown to HTML converts your Markdown (md) into ready-to-use HTML directly in your browser. Paste a README, documentation, or any Markdown text and instantly get the rendered HTML markup. It's handy whenever you need to embed Markdown-authored content into a web page, CMS, or email template.

Common uses

• Turn a project README or docs written in Markdown into HTML for a website or blog
• Generate HTML snippets to paste into a CMS or email template that doesn't accept Markdown
• Preview the exact HTML structure (headings, lists, links, code blocks) that a Markdown document produces
• Convert Markdown notes into HTML for static site content
• Quickly check how tables, blockquotes, or fenced code blocks translate to HTML tags

FAQ

Is my data sent to a server?

No. The conversion runs entirely in your browser using JavaScript, and nothing you type or paste is uploaded anywhere. The whole site is open source so you can verify this yourself.

What Markdown features are supported?

The tool uses the marked library, which supports CommonMark-style Markdown plus GitHub-flavored extras such as headings, lists, links, images, blockquotes, fenced code blocks, and tables. The output is the HTML markup these elements produce.

Does it render the HTML or show the source markup?

It outputs the raw HTML source as text so you can copy it. It does not display a visual preview of the rendered page.

Is the generated HTML sanitized?

No. marked passes through any inline HTML or scripts present in your Markdown as-is, so sanitize the output yourself before injecting it into a live page if the source is untrusted.

Is there a size limit on the input?

There is no fixed limit; conversion is synchronous and happens locally, so very large documents are constrained only by your browser's available memory and processing speed.
