Why use this markdown editor

Most online markdown editors make you sign up before you can even type. This one doesn't. Open the page, start writing, see the preview. That's it.

When you're ready to share, click Publish with MDtoLink and your markdown becomes a shareable URL. Good for meeting notes, READMEs, changelogs, API docs, or anything else you'd normally email as an attachment or paste into Slack.

The editor supports GitHub Flavored Markdown — so tables, task lists, and code blocks with syntax highlighting all work. Your published document looks clean and readable, not like a raw text dump.
