Frequently asked questions
How do I convert Markdown to HTML?
Type or paste your Markdown into the editor and switch to the Markdown → HTML mode (or open Live Preview and copy the generated HTML). You'll get clean, standards-compliant HTML you can paste straight into a website, email or CMS. The conversion is instant and happens as you type.
Can I convert HTML back into Markdown?
Yes. Paste your HTML into the HTML → Markdown mode and the editor turns it into tidy, readable Markdown — handy for migrating old content, cleaning up pasted rich text, or moving pages into a static-site generator.
Is my text uploaded anywhere?
No. Every conversion — Markdown to HTML and HTML to Markdown — runs entirely in your browser with JavaScript. Nothing you type ever leaves your device, so it's safe for private notes and internal docs.
Which Markdown flavour does it support?
A GitHub-flavoured subset: headings, bold/italic/strikethrough, inline and fenced code, ordered/unordered/task lists with nesting, blockquotes, horizontal rules, links, images and pipe tables.
Is the preview safe from malicious HTML?
Yes. The rendered preview is sanitised with DOMPurify before it is shown, so embedded scripts and dangerous attributes are stripped out and can't run.
Can I export my work?
Use Copy to grab the HTML or Markdown, or Download to save a .html or .md file. In Live Preview you can copy the generated HTML at any time.
Is this Markdown editor free?
Completely free, with no sign-up, watermark or usage limits. Because it runs locally in your browser there's no server cost, so you can use it as much as you like.
