html2png.dev is a free API that converts raw HTML and CSS into high resolution images (PNG, JPEG, WebP) or PDFs. It uses a headless Chromium instance on the edge to render markup exactly as a browser would, including Tailwind CSS, Google Fonts, SVG, JavaScript, and CSS animations. The API accepts a simple HTTP POST request with the HTML in the request body and returns a JSON response containing a public URL to the generated asset. Key parameters include width, height, format, deviceScaleFactor (1 4), delay, zoom, selector (to capture a specific element), and omitBackground (for transparent PNGs). The service is designed to be agent native, meaning LLM agents like Claude and GPT can call it directly without complex JSON escaping or MCP servers.
