why convert
Markdown and Slack use different syntax.
Slack uses mrkdwn, not standard markdown. Bold is one asterisk (*bold*), italic is underscore (_italic_), and links use angle brackets (<url|label>). Headings have no native equivalent — most teams bold the line instead.
Copying markdown straight into Slack leaves raw ** symbols, broken links, and headings that do not render. Converting once saves reformatting every announcement.
step by step
Convert and copy in under a minute.
- Open Markdown → Slack.

limitations
What Slack cannot render.
The tool strips elements with no Slack equivalent and shows a callout when something was removed:
- Images —
is removed. Upload images separately in Slack. - Raw HTML — tags are stripped. Slack does not parse HTML in messages.
Tables, footnotes, and complex nested markdown may not convert perfectly. For tables, consider Markdown Table Fixer first, then paste the result here if you need a plain-text version for Slack.
privacy
Browser-local only.
Your pasted markdown stays on your device. The converter does not send text to Tiny Design Shop or Slack. Your last input is saved in local storage on this browser only.
