Adobe Acrobat does not have this feature available yet.

Needs the following features online:

Preview GIF animations & Preview videos online.
Right now you can only view content as a static JPG you have to download all assets in order for the client to preview files.

This creates a redundant step for a client especially if they are not tech savvy.

Gifs have to be reopened with a browser & videos need to be viewed on the clients video player.

If the link is already online not understanding why you need to download & reopen in a browser to preview animations.

If you could create this feature it would help everyone overall and reduce time spent training individuals what to do.
+ speed up the approval process for getting artwork approved by the client.

Similar feature to dropbox you are able to play videos online, and GIF animation will automatically play when previewing them.
