HTML to Social Media Image Renderer

Turn any HTML/CSS into a pixel-perfect social media image. Send HTML, get back a public URL to a PNG/JPEG rendered at the exact canvas size you asked for.

Built for AI agents and automation pipelines that need to convert text/data into shareable visuals — Pinterest pins, OG images, X/Twitter cards, Instagram posts, YouTube thumbnails, quote cards, price tables, weekly report graphics.

Why this Actor

• Exact canvas control — you set width×height, your HTML renders on that canvas. No cropping surprises.
• Structured output — the result is JSON with a stable imageUrl (public key-value store link). No parsing needed.
• Web-font & emoji ready — full Chromium rendering. Inline <style>, Google Fonts <link>, flexbox/grid all work.
• Fast & cheap — a typical card renders in ~2-3 seconds.

Using from MCP (AI agents)

This Actor is callable through the Apify MCP server. Once connected, an agent can call it like a tool:

{
  "html": "<div style='width:1000px;height:1500px;background:#1a1a2e;color:#fff;font-family:sans-serif;padding:80px'><h1 style='font-size:80px'>5 Kitchen Storage Hacks</h1><p style='font-size:44px;color:#ffd166'>that actually survive Monday mornings</p></div>",
  "width": 1000,
  "height": 1500,
  "format": "png"
}

The dataset item returned:

{
  "imageUrl": "https://api.apify.com/v2/key-value-stores/XXXX/records/image.png",
  "width": 1000,
  "height": 1500,
  "format": "png",
  "bytes": 152340,
  "renderMs": 2400
}

日本語

HTML/CSSをそのままSNS画像（PNG/JPEG）に変換するAPIです。Pinterestピン、OGP画像、Xカード、Instagram投稿、YouTubeサムネイル、引用カードなどを、AIエージェントや自動化パイプラインから1リクエストで生成できます。

• html を送ると、指定した width×height のキャンバスでChromiumがレンダリングし、公開URL付きのJSONが返ります
• 日本語フォント・絵文字対応。Google Fontsの <link> もそのまま使えます
• Apify MCPサーバー経由でAIエージェントのツールとしても呼び出せます
