description
Take full-page screenshots of HTML files as PNG images using Chrome + puppeteer-core, without downloading any browser. Use when: (1) rendering a data visualization report and delivering it as an image, (2) converting an HTML page to a shareable screenshot, (3) the user asks for an image/PNG/PDF of an HTML report, (4) the canvas or browser tool is unavailable or impractical. Also generates PDF via Chrome's print-to-PDF.

Chrome Screenshot

Converts HTML files to PNG screenshots (or PDF documents) using the system's installed Chrome via puppeteer-core.

Prerequisites

  • Chrome installed at /Applications/Google Chrome.app/Contents/MacOS/Google Chrome
  • puppeteer-core installed globally: npm install -g puppeteer-core
  • Node.js

Script: scripts/screenshot.sh

scripts/screenshot.sh <html-file> [output-path] [width]
  • html-file: Path to the HTML file (required)
  • output-path: Output PNG path (default: /tmp/screenshot.png)
  • width: Viewport width in px (default: 420, good for mobile/微信)

The script:

  1. Starts a local HTTP server on port 8877
  2. Opens the HTML in headless Chrome via puppeteer-core
  3. Measures the full page height and captures a full-page screenshot
  4. Saves as PNG, cleans up the HTTP server

Usage

Screenshot an HTML report

bash scripts/screenshot.sh /path/to/report.html /tmp/output.png 420

Then send the image via the message tool:

{
  "action": "send",
  "media": "/tmp/output.png",
  "message": "📊 Report Title"
}

PDF output (optional)

Chrome's print-to-PDF can generate PDFs instead:

bash scripts/screenshot.sh /path/to/report.html /tmp/output.pdf 420

Notes

  • Do NOT use this skill for web browsing or page interaction—only for screenshotting locally authored HTML.
  • The HTML file is served via Python's http.server. Make sure python3 is available.
  • For the best visual result in the screenshot, author the HTML with an explicit width matching the screenshot width.
  • The HTTP server binds to 127.0.0.1 on port 8877.
