Use Selenium’s Java TakesScreenshot API to save a screenshot of the current browser context, and run Chrome headlessly with ChromeOptions on a Linux VPS. The example below saves a PNG using Java NIO and closes the browser even if navigation or file writing fails. It captures the current viewport; it does not, by itself, guarantee a full-page screenshot.
What you need
- A Java application with Selenium Java on its classpath.
- Google Chrome installed on the VPS, plus the operating-system libraries that browser needs.
- A Linux service account that can launch the browser and write to the screenshot destination.
Selenium Manager, included with Selenium releases from version 4.6, can manage a browser driver as a fallback when you have not supplied one yourself. Its binaries support Linux. ChromeDriver is a separate executable used by Selenium to control Chrome; for troubleshooting, check that the Chrome and ChromeDriver major versions match. See Selenium’s Selenium Manager documentation and ChromeDriver getting-started guide.
Capture a screenshot with Java
Add Selenium Java to your project using the dependency manager and version appropriate for your application. This standalone example uses Java NIO, so it does not require the Apache Commons IO helper used in Selenium’s documentation example.
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.StandardCopyOption;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
public class ScreenshotPage {
public static void main(String[] args) throws Exception {
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless=new");
options.addArguments("--window-size=1440,1000");
WebDriver driver = new ChromeDriver(options);
try {
driver.get("https://example.com");
Path destination = Path.of("/tmp/example.png");
Files.copy(
((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE).toPath(),
destination,
StandardCopyOption.REPLACE_EXISTING
);
System.out.println("Saved screenshot to " + destination.toAbsolutePath());
} finally {
driver.quit();
}
}
}Replace the example URL and destination with your own. The output type is PNG. The explicit window size makes the viewport more predictable, but does not make the capture full-page. Choose a destination the process can write to. Selenium’s Java screenshot example uses the same TakesScreenshot and OutputType.FILE approach; see Working with windows and tabs — TakeScreenshot.

Configure Chrome for headless Linux
Pass ChromeOptions to ChromeDriver, as in the sample. Selenium’s Chrome-specific documentation lists --headless=new among common arguments; confirm that the installed Chrome version supports it. If it does not, use a headless argument supported by that version rather than assuming every VPS image has the same browser build. Refer to Selenium’s Chrome-specific functionality guide.
Headless mode removes the need for a graphical desktop, but it does not remove Chrome’s operating-system dependencies. If Chrome fails to start with a missing shared-library error, use the exact library name in the error to diagnose the VPS image. Selenium Manager’s Linux documentation includes examples of such errors for browsers; avoid blindly installing a package list intended for a different distribution.

Decide what the screenshot should include
Current viewport
The basic TakesScreenshot call captures the current browsing context. Set the window dimensions before navigation if the viewport must be consistent, and wait for the page state your task needs before taking the shot. A page that has not finished rendering, or content that loads after the initial navigation, may not appear in the image.
A single element
Selenium also documents element-level screenshot capture. Use that when the requirement is one visible element rather than the browser viewport; consult the Selenium screenshot documentation for the API example. Element capture is a different scope from capturing the current browsing context.

Entire scrollable page
Do not treat the sample as a full-page capture. The cited Java example does not establish that it captures content beyond the viewport. If the whole page is required, select and verify a full-page method supported by your chosen browser and Selenium version, and test it on pages with long content and lazy-loaded images.

- Check the server image. Confirm that the Linux distribution can run your Java runtime, Chrome build, and required browser libraries.
- Check browser and driver startup. Run the application as the same service user that will take screenshots. If session creation fails, inspect both browser and driver versions and their startup logs.
- Check permissions. Make sure the service user can write to the configured output path and that the destination has enough storage for your retention needs.
- Check network access. Confirm the server can reach the target site over the required outbound routes. A site may also behave differently when accessed from the VPS’s location.
- Plan for your workload. Assess CPU, memory, storage, and bandwidth against the concurrency and page complexity you actually expect; no universal VPS resource minimum is established for this workload.
- Keep diagnostics. Retain application and browser startup logs so you can distinguish driver, library, permission, network, and page-readiness failures.
- Coordinate updates. Keep Chrome and ChromeDriver compatible when updating either component.
Troubleshoot common failures
| Symptom | Likely cause | What to check |
|---|---|---|
| Chrome session fails to start | Chrome and ChromeDriver major versions do not match, or Chrome cannot launch in the server environment. | Check both versions, the browser startup error, and whether Chrome’s required libraries are installed. |
| Driver executable cannot be found | No driver was supplied and automatic management did not complete, or the driver is unavailable in the environment. | Check Selenium Manager diagnostics and network access; alternatively, configure a compatible driver explicitly. |
| Missing shared-library error | A required operating-system library is absent from the VPS image. | Use the library named in the actual error to identify the matching package for that Linux distribution. |
| Screenshot is missing or cannot be saved | The process cannot write to the chosen directory, or the file operation failed. | Check the service user’s permissions, destination path, available storage, and application exception logs. |
| Image is blank or content is absent | Navigation may not have reached the needed page state, content may load later, or the site may respond differently to the server request. | Log the current URL and page state, wait for the required content, and check outbound access and site behavior. |
| Only the visible portion appears | The basic screenshot call captures the current browsing context, not necessarily the full scrollable document. | Use a verified full-page capture method for the selected browser and Selenium version. |
Performance, reliability, and cost considerations
Launching a browser and loading a page are part of the work, so measure the end-to-end time and resource use on your actual VPS and pages before selecting concurrency. Keep browser sessions short-lived where appropriate and always call quit() in a finally block to reduce the chance of orphaned browser processes after an exception. No fixed performance figure or VPS resource minimum applies to all sites and workloads.
Account for failures beyond Java code: browser startup, missing libraries, permissions, network access, and pages that do not reach the state you need. Log enough context to diagnose those conditions without recording sensitive page data or credentials.

Or skip the browser setup
If you need a screenshot endpoint instead of maintaining Chrome and Selenium on a VPS, ScreenshotNeo is a website screenshot API and MCP server. Its API accepts one GET request with a URL and can return PNG, JPEG, WebP, or PDF. For Java, use a standard HTTP client or Java’s built-in HttpClient to make the same request; the cURL, Python, and Node.js examples below show the endpoint and parameters.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com -o shot.webpSee the ScreenshotNeo API documentation for request options and response details. Cookie banners are accepted and removed before capture, along with known newsletter popups and chat widgets; each cleanup step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits cost nothing, with response headers indicating the page verdict and billing status. Its MCP server provides take_screenshot, get_page_info, and capture_pdf for AI agents. The Free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots.
