Slack message formatter

Long updates get scrolled past. Paste yours and get a Slack-ready message with bold lead-ins and short blocks, in Slack’s own formatting.

Works in your browser. Your words are never rewritten.

Real Slack formatting

Bold uses Slack’s *asterisk* style, so it shows up correctly in channels, threads and Discord.

Dense paragraphs are split so each point stands on its own line.

One click copies the message, ready for the composer.

The same paste also gives you the blog, email, LinkedIn, X, Notion, Slack and Reddit versions, side by side, each with its own copy button.

Does Slack support Markdown?

Slack uses its own variant called mrkdwn: *bold*, _italic_ and > quotes. This tool writes that format for you.

Does it work for Discord?

Yes. Discord reads the same bold and paragraph breaks.

Will it rewrite my message?

No. Only the structure changes. Your words stay yours.

Is it free?

Yes, with no signup.
