Diagram to Image Converter
Converts Mermaid diagrams and Markdown tables into high-quality PNG images for platforms that lack native rich text support.
This Claude Code skill streamlines the process of turning technical visualizations and data tables into professional, shareable assets. By leveraging the mermaid-red API, it transforms Mermaid syntax and Markdown tables into styled PNG images without requiring heavy local dependencies like Puppeteer or Chromium. The skill intelligently detects project structures to save images in appropriate directories—such as /assets, /public, or /images—and automatically generates descriptive filenames based on the content, making it an essential tool for technical documentation, blog posts, and social media sharing.
