About Markdown in Slack
Slack supports a limited dialect of Markdown ("mrkdwn") that differs from GFM in several ways: bold uses single `*` instead of `**`, italic uses `_text_` only (not `*text*`), code blocks don't support a language tag, and tables are not supported at all — they paste as wrapped text. Nested lists render but often lose indentation. For Slack canvases (the newer document feature), the editor is closer to standard GFM. Best practice: convert long Markdown documents to plain text or screenshots when posting in channels; use Slack's native triple-backtick syntax for inline code snippets.
Slack-specific workflow
- For short messages: copy Markdown directly — Slack converts simple bold/italic/code inline.
- For longer docs with tables: export to a screenshot or PDF first, then attach to your Slack message.
- For canvases: paste Markdown directly into a new canvas — the editor supports more GFM than channel messages.
- For plain channel posts, strip Markdown syntax with the Markdown to Text tool so no stray symbols remain.
Slack workflow scenarios
- Share release notes written in Markdown in a team channel.
- Post a Markdown checklist or runbook into a Slack canvas.

FAQ
Can I paste Markdown straight into Slack?
Simple Markdown often survives a direct paste, but tables, nested lists, and code blocks are more reliable when you convert first with the recommended tinyMD tool and paste the result into Slack.
Does tinyMD upload my Markdown while preparing it for Slack?
No. tinyMD tools run in your browser, so your source files stay on your device while you convert and copy the output.
