Webpage Screenshot Tool

📌 Overview

This Python script captures a screenshot of a given webpage at a specified resolution and aspect ratio. It utilizes Selenium to automate Chrome and take a screenshot at the desired dimensions without cropping or resizing.

🚀 Features

• Capture a full-page screenshot at a specified resolution (e.g., 1920x1080 for 16:9).
• Uses headless Chrome for efficient rendering.
• Supports custom resolution input.
• Fully automated with Selenium WebDriver.

📦 Requirements

1. Install Dependencies

You need to install Selenium and Validators:

pip install selenium validators

2. Install Google Chrome

Ensure that Google Chrome is installed on your system.

3. Install ChromeDriver

To install ChromeDriver:

1. Find your Chrome version:

   • Open Chrome and go to chrome://settings/help
   • Note down the version number (e.g., 120.0.0.1)

2. Download the corresponding ChromeDriver version from:

   • ChromeDriver Downloads

3. Extract and place chromedriver in the project directory or add it to your system PATH.

4. Add ChromeDriver to PATH

macOS

echo 'export PATH="$PATH:~/path-to-chromedriver"' >> ~/.zshrc
source ~/.zshrc

Windows

1. Move chromedriver.exe to a folder (e.g., C:\chromedriver)
2. Open System Properties → Advanced → Environment Variables
3. Under System Variables, find Path and click Edit
4. Click New and add C:\chromedriver
5. Click OK, restart the terminal, and verify with:

chromedriver --version

Linux

echo 'export PATH="$PATH:/path-to-chromedriver"' >> ~/.bashrc
source ~/.bashrc

💻 Usage

Run the script:

python screenshot.py

Provide the inputs:

• Enter the URL of the webpage.
• Specify width (e.g., 1920 for Full HD resolution).
• Specify height (e.g., 1080 for a 16:9 ratio).

Example Input:

Enter URL: https://example.com
Enter width: 1920
Enter height: 1080

The script will generate a screenshot.png file in the current directory.

⚙️ How It Works

1. Launches headless Chrome with the specified window size.
2. Loads the webpage and waits for full rendering.
3. Takes a screenshot at the exact resolution specified.
4. Saves the screenshot without resizing or cropping.

🛠 Troubleshooting

ChromeDriver version mismatch

If you get an error related to ChromeDriver, make sure you have:

• The latest version of Google Chrome installed.
• The correct version of ChromeDriver matching your Chrome version.

Webpage not fully loaded in screenshot

Increase the time.sleep(3) value in the script to allow more time for the webpage to load.
