0 bytes uploaded. Markdown to Slack runs entirely in your browser using JavaScript. Your markdown — including any secrets, PII, or proprietary content — never leaves your device. No data is sent to any server.
Slack's mrkdwn format supports bold (*text*), italic (_text_), inline code (`text`), code blocks (```), bullet lists (• ), and links (<url|label>). It does not support headings, horizontal rules, or images — these are stripped or converted to plain text equivalents.
This tool outputs plain mrkdwn text suitable for Slack message text fields and section blocks. For full Block Kit JSON generation, use a dedicated Block Kit builder.
