So you are wondering if Pinterest supports GIFs, right?
The answer is YES, in a way.
Pinterest used to support uploading GIFs directly, but that seems to have changed at some point in 2021.
Here is a post from Reddit, with a user confirming that Pinterest support told them that GIFs are no longer supported on Pinterest:
If you try to upload a GIF to Pinterest, it seems like it will let you, but instead it will just be uploaded as a static image, rather than a GIF.
However, here is how you can upload GIFs to Pinterest
Using the social media scheduling tool OneUp, you can schedule Pinterest pins with a GIF and it will actually post WITH the GIF 🤓
OneUp has a Free Plan, and supports Pin Titles, Descriptions, and Destination Links.
