markdown-to-image: Turn Markdown into Social Images

Overview

markdown-to-image renders Markdown into poster-style images through a React component, and also provides a web editor. It helps developers and content creators turn text into shareable visual cards without building a rendering workflow from scratch.

Use it when you want Markdown-based content presented as social media graphics, or when you need to embed poster creation in a React application. The project also offers an online editor and a deployment path for hosting your own editor.

Key Features

• Render Markdown as poster images for social sharing.
• Integrate rendering into React projects with Md2Poster and its content, header, and footer components.
• Choose from nine built-in themes and customize templates.
• Copy the rendered output as an image.
• Copy output as HTML for use in emails and editors.
• Use an integrated CORS proxy to insert online images into posters.
• Try the hosted editor or deploy the example editor with Vercel.

Use Cases

• A developer adds Markdown-based quote or announcement cards to a React application.
• A creator turns notes or short articles into visual posts for social platforms.
• A team creates consistently themed posters using custom headers, footers, and templates.
• A user who does not need an application integration creates posters in the hosted editor or deploys the example editor.

Getting Started

Install the package:

npm i markdown-to-image

Import its stylesheet and React components to use it in an application. See the README for the integration example and editor deployment instructions.

Considerations

• The component is intended for React applications; the web editor is provided separately in the example path.
• The README notes that server-side rendering can fail with document is not defined. In frameworks such as Next.js, load the component dynamically with server-side rendering disabled.
• The README lists more built-in templates as planned, so template availability may not cover every design need.
• Online images depend on browser image access; the project includes a CORS proxy to help with insertion.
