## **Overview**

Aspose.Slides allows you to convert PowerPoint presentations to animated GIF files with just a few lines of code. This is useful when you need to share slide content in a lightweight, widely supported animated format that can be embedded in web pages, messengers, or documentation. This article explains how to export a presentation to GIF using default settings and how to customize the output by configuring options such as frame size, slide delay, and transition frame rate through [GifOptions](https://reference.aspose.com/slides/nodejs-java/aspose.slides/gifoptions/).

## **Converting Presentations to Animated GIF Using Default Settings**

This sample code in JavaScript shows you how to convert a presentation to animated GIF using standard settings:

```javascript
var pres = new aspose.slides.Presentation("pres.pptx");
try {
    pres.save("pres.gif", aspose.slides.SaveFormat.Gif);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}
```

The animated GIF will be created with default parameters.

If you prefer to customize the parameters for the GIF, you can use the [GifOptions](https://reference.aspose.com/slides/nodejs-java/aspose.slides/GifOptions) class. See the sample code below.

## **Converting Presentations to Animated GIF Using Custom Settings**

This sample code shows you how to convert a presentation to animated GIF using custom settings in JavaScript:

```javascript
var pres = new aspose.slides.Presentation("pres.pptx");
try {
    var gifOptions = new aspose.slides.GifOptions();
    gifOptions.setFrameSize(java.newInstanceSync("java.awt.Dimension", 960, 720));// the size of the resulted GIF
    gifOptions.setDefaultDelay(2000);// how long each slide will be showed until it will be changed to the next one
    gifOptions.setTransitionFps(35);// increase FPS to better transition animation quality
    pres.save("pres.gif", aspose.slides.SaveFormat.Gif, gifOptions);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}
```

## **FAQ**

### What if the fonts used in the presentation aren’t installed on the system?

Install the missing fonts or [configure fallback fonts](/slides/nodejs-java/powerpoint-fonts/). Aspose.Slides will substitute, but the appearance may differ. For branding, always ensure the required typefaces are explicitly available.

### Can I overlay a watermark on the GIF frames?

Yes. [Add a semi-transparent object/logo](/slides/nodejs-java/watermark/) to the master slide or to individual slides before export — the watermark will appear on every frame.
