cli2pdf 📄

cli2pdf is a lightweight Node.js tool that uses Playwright (Chromium) to convert web pages into high-fidelity PDFs.

Unlike standard "Print to PDF" functions, this tool is designed to capture infinite scroll websites without cutting content or text between pages. It dynamically adjusts the PDF height to fit the entire web page as one continuous strip.

🚀 Features

• No Page Breaks: Creates a single, continuous PDF file. Perfect for chat logs, documentation, wikis, or long articles.
• Infinite Scroll Support: Automatically scrolls to the bottom of the page to trigger lazy-loading images and content before capturing.
• Visual Fidelity: Forces "Screen Mode" to capture the site exactly as it looks on a monitor (ignoring print stylesheets that hide content).
• Full HD Mode: Optional flag to force a 1920px width rendering.
• Open Source: Licensed under GPLv3.

📦 Dependencies

This project relies on the following core technologies:

• Node.js (Runtime environment)
• Playwright (For browser automation)
• Chromium Browser (Managed automatically by Playwright)

🛠️ Installation

1. Download and Locate: Download the repository (or git clone it) and open PowerShell or your terminal inside the cli2pdf folder.

cd cli2pdf

2. Install dependencies: This command installs the required Node.js libraries defined in package.json.

npm install

3. Install the browser binary: This downloads the specific version of Chromium needed for the PDF generation.

npx playwright install chromium

💻 Usage

Run the script using Node.js with the URL you want to capture:

Standard Mode (Auto-width)

Best for most websites. It adapts to the site's natural width (usually 1280px).

node index.js "https://es.wikipedia.org/wiki/Internet"

Full HD Mode (Fixed 1920px)

Forces the browser to render at 1920px width. Useful for wide layouts or preserving desktop fidelity.

Use the flag --fhd

node index.js "https://es.wikipedia.org/wiki/Internet" --fhd

📂 Output

The PDF will be generated in the same folder with a timestamped filename, for example:

Internet_-_Wikipedia_2026-02-06T21-30.pdf
