Markdown to HTML

Markdown is the fastest way to write formatted text without lifting your hands off the keyboard. But at some point it has to become HTML - for a website, an email template, a CMS or a newsletter. This tool makes exactly that step visible and instant: you type Markdown and see live what HTML it produces.

The view splits freely. Editor and output side by side when you want to watch the result change as you write. Editor only when you are focused on writing. Output only when you are checking the result. You can show the output either as a rendered preview or as raw HTML source.

The full range of Markdown is supported: multi-level headings, bold and italic, ordered and unordered lists, nested lists, links and images, blockquotes, inline code and whole code blocks, plus tables. From the headings the tool can build a table of contents so you keep an overview of longer documents.

Security is built in. Before the HTML lands in the preview or you copy it, it is sanitised with DOMPurify. Injected scripts or dangerous attributes are stripped out, so you can drop the result into your page with confidence - especially when the Markdown comes from an untrusted source.

So nothing gets lost, the tool autosaves your draft locally in your browser every two seconds. If you close the window by accident, the text is back next time you open it. Copy the HTML with one click or download it as a file, and example templates show you common Markdown structures to get started quickly.

Everything runs in the browser. No text is sent to a server, nothing is stored except the local draft only you can see. That makes the tool fast, data-frugal and usable offline.
