You can easily upload your GIF files of 10MB or smaller to a GIF Post type:
When creating a new post:
Select GIF as your post type.
Fill in any text in the message portion of this post.
Click the Browse File box. A new window will pop up where you can select the GIF you want to upload (up to 10MB).
Finish filling out the rest of the required info on this page.
Click the Create button to save.
If your GIF won’t upload and you’ve created it yourself on a program like Canva, it might be too big. 10MB is the size limit for GIFs.
You can re-download that GIF file from the program you created it on. Choose a lower quality/resolution when downloading.
Note: If you have a link to the GIF instead, you can choose the Website Link post type.
Just know that guests might have to click on that GIF link to view it.
