Markdown to Slack
Slack has its own take on Markdown: single asterisks for bold, and no headings or tables. Paste standard Markdown and get a message that looks right in Slack, whether you paste it or a bot sends it.
Loading Markdown to Slack…
Runs on your device. Nothing you type or paste is uploaded.
How to use the Markdown to Slack
- Paste your Markdown, from a README, a document or an AI chat.
- Choose “Pasting into Slack” for the message box, or “Bots, webhooks and the API” for a message’s text in code.
- Copy the result. The preview shows roughly how Slack will display it.
Private by design
Many online converters send your text to their server, which matters for drafts, notes and anything confidential. Markdown to Slack runs entirely in your browser: nothing is uploaded, logged or stored on a server, and it keeps working with your network switched off. It’s free, with no account and no limits.
Questions
Why does Markdown look wrong when pasted into Slack?
Slack’s formatting is close to Markdown but not the same: **bold** shows its asterisks, headings and tables aren’t supported, and links use another syntax. This converts each of those to what Slack understands.
What’s the difference between the two options?
Slack’s message box doesn’t understand <address|text> links, so for pasting they’re written as text (address), and characters like & stay as they are. Messages sent by bots and webhooks are read as mrkdwn, where links are <address|text> and &, < and > must be escaped, so that output follows those rules.
What happens to tables and headings?
Slack has neither, so headings become bold lines and tables are lined up in a code block, which keeps the columns readable in its fixed-width font.
Is my text uploaded anywhere?
No. Everything runs in your browser, so drafts, notes and documents stay on your device, and the tools keep working offline once the page has loaded.
Do I need an account?
No. Every Markdown tool is free to use without signing in, with no limits.
