FAQ
LinkedIn doesn't render Markdown. SocialMarkdown converts bold and italic to Unicode Mathematical characters that look formatted visually. Switch to Article mode for clean HTML you can paste into LinkedIn's article editor.
No. Everything runs locally in your browser. No servers, no accounts, no data collection.
When your text exceeds a platform's character limit — 280 on X, 500 on Threads and Mastodon, 300 on Bluesky — SocialMarkdown automatically splits it into numbered posts at paragraph and section boundaries. Each post gets its own copy button.
LinkedIn, X, and Threads each have two modes. Post optimizes for the platform's standard post format with character limits and thread splitting. Article generates clean HTML for long-form article editors.
Slack uses its own markup: *bold*, _italic_, ~strikethrough~, and <url|text> for links. SocialMarkdown converts your Markdown to Slack's native format automatically.
Both platforms support Markdown natively, so your bold, italic, links, and lists render correctly as-is. The output shows a rendered preview — Copy grabs the raw Markdown.
SocialMarkdown detects rich text on paste and auto-converts it to Markdown. Paste from anywhere and it becomes clean Markdown ready for any platform.
Click Export All in the action bar. Choose CSV for a spreadsheet with every platform's output, or ZIP for individual text files per platform — including split thread posts as separate files.
Email/Blogs gets rich HTML. LinkedIn posts get Unicode bold/italic. X, Threads, Bluesky, and Mastodon get plain text with auto thread splitting. Reddit and Discord keep raw Markdown. Slack gets its own markup. LinkedIn, X, and Threads also offer Article modes.
