Adding a GIF to a Word document is useful if you want to convey a message, show an activity, grab the audience, or just have fun. Here's how to add a GIF to Microsoft Word.
Word lets you import GIFs stored on your computer hard drive. The process of inserting a GIF into a Word document is no different than inserting an image or other object. Unfortunately, this only works in Microsoft Word for Windows 10. If you are a Mac user, you can still import a GIF, but it will not be animated.
First, open Word and place the cursor in the position of the document where you want the GIF to appear. On the Insert tab, click on "Pictures". Select "This Device" from the drop-down menu.
File Explorer will open. Locate and select the GIF you want to import. Click on "Insert".
The GIF will appear in the Microsoft Word document. You will see a pause icon in the lower left corner of the image. Clicking on it will stop it animation.
You will also see the alternative text at the bottom of the GIF. Word automatically tries to add alt text for you, but it is not always accurate. To make the Word document more accessible, write a descriptive alternative text. To edit the alt text of your GIF, click on the text at the bottom.
Alternatively, right-click on the GIF, then select "Edit Alt Text" from the context menu.
The Alt Text window will appear to the right of the window. Enter the desired alt text in the text box.
Not only have you added a GIF to your Microsoft Word document, but you have made it accessible to everyone.
