Next, I will show you how to save an Illustrator document as a GIF file. Go to the top of your Illustrator window and click File > Save For Web. You will see the same box that you seen when you saved the file as a JPEG. The difference is you will need to drop the top box down and select GIF. Then click Save and enter a name for your document in the box that opens. Then click the Save button again.
Those are the three different ways to save an Adobe Illustrator document.
