Convert GIF in Java

Java library allows Java developers to convert GIF images easily. GIF image conversion engine analyses the original GIF content, then exports the combined graphical content to the required format.

GIF image conversion may be tricky, unless you have a professional tool to do the job. Use Java to convert GIF images with maximum flexibility and speed. Run online live demo and check the highest image quality right in a browser. GIF Conversion API supports a bunch of useful options.

Merge GIF in Java

Enhance GIF image format capabilities with Aspose.Words for Java. This is a simple way to combine GIF images with Java library that handles all low-level details.

Merge GIF images and save the result as a single file. If you develop code in Java, this will be simpler than it sounds. See Java example that iterates through GIF images and combines them:

Code example in Java to merge GIF files
Upload a file you want to merge
Run code
Upload a file you want to merge
Select the target format from the list
import com.aspose.words.*;

List<String> fileNames = Arrays.asList("Input1.gif", "Input2.gif");

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

List<Shape> shapes = fileNames.stream().map(fileName -> {
    try {
        return builder.insertImage(fileName);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}).collect(Collectors.toList());

// Calculate the maximum width and height and update page settings 
// to crop the document to fit the size of the pictures.
PageSetup pageSetup = builder.getPageSetup();
pageSetup.setPageWidth(shapes.stream().mapToDouble(shape -> shape.getWidth()).max().getAsDouble());
pageSetup.setPageHeight(shapes.stream().mapToDouble(shape -> shape.getHeight()).sum());
pageSetup.setTopMargin(0);
pageSetup.setLeftMargin(0);
pageSetup.setBottomMargin(0);
pageSetup.setRightMargin(0);

doc.save("Output.gif");
Run code
