SiteShoter is a lightweight, portable freeware utility developed by NirSoft that automates saving screenshots of any webpage. It works by running a hidden browser instance in the background, loading the target page, and stitching the full contents together into a single image file.
You can automate screenshots with SiteShoter using its interactive graphical user interface (GUI) or scale it up programmatically using the command-line interface (CLI). Method 1: Automating with the GUI Mode
The visual interface is ideal for quickly processing small lists of URLs without writing code.
Inputting URLs: Select “Multiple URLs/Files” instead of a single page. You can upload a standard .txt file containing a list of target web addresses.
Setting Dimensions: Check the option to automatically expand the window to fit content. This forces SiteShoter to scroll and stitch a full-length page rather than cropping at standard screen limits.
Configuring Elements: Use the toggle switches to enable or disable dynamic assets like JavaScript or Flash, which prevents broken scripts from halting the automation.
Automatic Looping: Adjust the time-based scheduler built directly into the interface. You can program the app to re-run the capture cycle every few seconds, minutes, or hours. Method 2: Automating with Command-Line Interface (CLI)
For strict and unattended automation, running SiteShoter in headless CLI mode allows you to execute commands via script files. Core CLI Syntax
Open your Command Prompt (cmd) or terminal and run the execution command using this formatting:
SiteShoter.exe /url [TargetURL] /Filename [OutputPath] [Additional Parameters] Use code with caution. Practical Examples
Single Full-Length Capture: Save a complete rendering of an entire site canvas to a local directory:
SiteShoter.exe /url “https://example.com” /Filename “C:\Screenshots\example.png” /ExtendFolder 1 Use code with caution.
Bulk URL List Capture: Read from an existing text file (urls.txt) and output a sequential batch of screenshots automatically:
SiteShoter.exe /urlsfile “C:\Data\urls.txt” /SaveFolder “C:\Screenshots” /ExtendFolder 1 Use code with caution. Key Command-Line Parameters
/ExtendFolder <0 or 1>: Setting this to 1 automatically forces the hidden browser window to lengthen, ensuring a full-page capture.
/BrowserWidth & /BrowserHeight : Restricts the viewport size, perfect for generating mobile or desktop-specific views.
/DisableJavaScript <0 or 1>: Turns off JavaScript loading if a webpage is lagging your machine. Setting Up a Automated Schedule
Because SiteShoter operates cleanly via command strings, you can build a recurring task using Windows Task Scheduler:
Save your SiteShoter CLI script inside a plaintext file and change its file extension to .bat (e.g., run_snapshots.bat). Open Windows Task Scheduler and select Create Basic Task.
Choose your frequency trigger (e.g., Daily, Weekly, or On Startup).
Set the Action parameter to Start a program and map it directly to your newly created .bat script.
If you would like to set up a automation script, let me know: What operating system version you are targeting Whether you need mobile, tablet, or desktop dimensions How frequently the script needs to repeat its run cycle
