What this tool does
Paste any Markdown text into the input and see it instantly converted to clean HTML. You can preview the rendered output or switch to the raw HTML view to copy the markup.
When you need this
Markdown-to-HTML conversion is useful when you write content in Markdown but need to publish it somewhere that only accepts HTML — a CMS, an email template, or a custom webpage. It is also useful for double-checking how your Markdown will render before committing it to a repository.
Supported syntax
This tool uses the marked.js library and supports standard Markdown including headings, bold, italic, links, images, lists, code blocks, blockquotes, and tables via GitHub Flavored Markdown.
Frequently asked questions
- What is Markdown?
- Markdown is a lightweight markup language that uses plain-text syntax to describe formatting. For example, wrapping text in **double asterisks** makes it bold, and a # prefix creates a heading. It is widely used in documentation, README files, and content management systems.
- Is the conversion done server-side?
- No. This converter runs entirely in your browser using the marked.js library. Your content is never sent to any server.
- What Markdown flavour does this support?
- This tool uses marked.js, which supports CommonMark plus several GitHub Flavored Markdown (GFM) extensions including tables, strikethrough, and fenced code blocks.
- Can I use this HTML output directly on a website?
- Yes, with caution. The output is standard HTML that should work in any browser. If the Markdown was written by untrusted users, sanitise the HTML before inserting it into a page to prevent XSS vulnerabilities.
