How to screenshot a website/URL in Java

Today we will be looking at how to set up screenshotting of websites in as simple a way as is possible. We will use one of Cloudmersive’s APIs to accomplish this with a minimum of effort.

So let’s get started by using Jitpack to compile the library we will be using. Add a reference to the repository in your Maven POM file:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

And then a reference to the dependency:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v2.32</version>
</dependency>
</dependencies>

Now all that’s left is to call convertWebUrlToScreenshot:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.ConvertWebApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
ConvertWebApi apiInstance = new ConvertWebApi();
ScreenshotRequest input = new ScreenshotRequest(); // ScreenshotRequest | Screenshot request parameters
try {
    byte[] result = apiInstance.convertWebUrlToScreenshot(input);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling ConvertWebApi#convertWebUrlToScreenshot");
    e.printStackTrace();
}

And that’s it! We are returned a screenshot of the requested dimensions from the specified URL.
