From markdown to Substack in three steps.
Write in your favorite markdown editor, then paste the content into DownStack's editor. We support full GitHub Flavored Markdown including tables, code blocks, blockquotes, and more.
See exactly how your content will look in Substack with a live preview. Tables are rendered as clean, styled images. Code blocks are formatted. Typography matches Substack's aesthetic.
Click "Copy for Substack" and paste directly into the Substack editor. Your content arrives fully formatted with tables rendered as permanently hosted images. That's it. Done.
Markdown tables are automatically converted to styled images and hosted permanently. They display perfectly in every email client and browser.
Bold, italic, links, lists, blockquotes, and headings all convert cleanly to Substack-compatible rich text formatting.
Fenced code blocks are preserved with proper monospace formatting. Syntax highlighting as images is coming soon.
Mermaid diagrams are rendered as images automatically. Create flowcharts, sequence diagrams, and more right in your markdown.
You publish data-heavy content with comparison tables, valuation metrics, and portfolio breakdowns. DownStack makes your tables look professional.
You write in markdown natively and include code snippets, architecture diagrams, and technical specifications. DownStack preserves your formatting.
You publish survey results, competitive analyses, and structured data. DownStack ensures your tables render cleanly for every subscriber.
If you've ever spent 20 minutes re-formatting content that already looked perfect in markdown, DownStack is for you.
