TLDR: Upload a 470px width GIF to giphy.com and share the link on Facebook.
Sadly, posting a GIF on Facebook is not that easy. If you upload your GIF as normal image, it will not be animated. To post a animated on Facebook you need to upload the GIF to another webservice and share the Link on Facebook. We use giphy.com as a service to host our GIFs. Another requirement is that the GIF should not have a width of more than 470 pixel and it must have a minimum size of 200x200px. Otherwise the GIF will not be shown correctly. Here is a step by step intro:
- Resize image to maximal 470px width and a minimum of 200x200px. Loopagain does that automatically for you
- Login to giphy.com
- Upload the GIF in giphy.com
- Copy the Link from the uploaded file. You need to use the one that ends with “.gif”
- Paste the link in Facebook
- Send you post
If you still have problems bringing the GIF to Facebook you can use a Debug Tool from Facebook. This tool allows you to remove your current version from the internal Facebook cache and reload the GIF again. You can find the tool here:
Paste the link of your GIF in the input field and click “Fetch new scrape information”. After that you should see a preview of your GIF (not animated) in the section “When shared, this is what will be included”.
