How to Convert an Image to PNG Format with Java

If you’re looking for a whole bunch of Image file format conversion APIs, you’ve come to the right place. Try starting out with our PNG File Conversion API and implement easily using ready-to-run code snippets provided below in Java (installation with Maven).

To begin Java SDK installation with Maven, first add a reference to the repository in pom.xml:

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

After that, add one to the dependency:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v4.25</version>
</dependency>
</dependencies>

Now you can add the import classes, include your Cloudmersive API key (obtainable by creating a free account on our website Home — Cloudmersive APIs), and call the function:

// 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.ConvertApi;
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");
ConvertApi apiInstance = new ConvertApi();
File imageFile = new File("/path/to/inputfile"); // File | Image file to perform the operation on.  Common file formats such as PNG, JPEG are supported.
try {
    byte[] result = apiInstance.convertToPng(imageFile);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling ConvertApi#convertToPng");
    e.printStackTrace();
}
