The Raycast extension provides six commands for bidirectional clipboard conversion on macOS. Install from the Raycast Store.
- One-click conversion – Read HTML from the clipboard and convert it to Markdown using Turndown.
- Context menu integration – Right-click on selected text anywhere on the web and choose "Copy as Markdown" to convert and copy formatted content instantly.
- Smart fallback – Gracefully handles plain text when no rich content is available.
- Automatic copy-back – Immediately writes the generated Markdown to your clipboard after each conversion.
- Live paste listener – Supports keyboard pastes (
Cmd/Ctrl + V) directly inside the popup. - Word-aware headings – Promotes Microsoft Word clipboard headings so Markdown keeps its structure.
- Google Docs normalization – Cleans up Docs-specific spans and non-breaking spaces so the output stays readable.
- Monospace heuristics – Detects Courier-style Word paragraphs and emits fenced code blocks.
- Bold span detection – Upgrades inline
font-weight: boldspans into Markdown**strong**text. - Image support – Includes conversion of inline images (beware large images will result in massive Markdown!)
- Click the extension icon to open the popup.
- Press Paste & Convert or press
Cmd/Ctrl + Vwith formatted content on your clipboard. - The Markdown appears in the output area and is automatically copied back to your clipboard so you can paste it wherever it's needed.
- Select any formatted text on a webpage, document, or local HTML file.
- Right-click on the selection and choose "Copy as Markdown" from the context menu.
- The converted Markdown is automatically copied to your clipboard – no popup needed!
