Convert Markdown to Slack mrkdwn
Turn standard Markdown into Slack mrkdwn — bold, italic, strikethrough, links, and headings mapped to Slack's syntax.
Direct answer
Paste your Markdown and convert it to Slack mrkdwn: ** becomes a single asterisk for bold, [text](url) becomes <url|text>, ## headings become bold, and ~~strike~~ becomes a single tilde. Code blocks and inline code are preserved. Copy the result into a Slack message or app payload.

Common mistakes
- Markdown bullet lists (- item) stay as text with a dash; Slack renders them as lines, not styled bullets, in bot and API messages.
- Do not leave double asterisks; mrkdwn bold is a single asterisk.
- Reference-style links must be inlined for Slack, since mrkdwn only supports inline <url|text> links.
FAQ
- How do I convert Markdown to Slack format?
- Paste the Markdown, choose Slack, and convert. Bold, italic, strikethrough, links, and headings are mapped to mrkdwn, and code blocks are preserved.
- What happens to Markdown headings in Slack?
- Slack mrkdwn has no heading syntax, so headings are converted to bold text, which is the closest visual equivalent in a message.
- Does the conversion keep my code blocks?
- Yes. Fenced code blocks and inline code use the same backtick syntax in Slack mrkdwn, so they are preserved as-is.
