Gifs are a great way to add a bit of flair to your Discord server. But how long can a Discord banner gif be? The current file size limit for uploading files to Discord is eight MB. Therefore, your profile picture or PFP must be within this limit. When you're setting up your server, you can also add a Discord banner background image and also a Discord server invitation presentation image.
Discord gives you plenty of screen space for these images, allowing you to customize your server. Discord banner background images can be up to 960 pixels wide by 540 pixels high, and server invitation welcome images can be 1920 pixels wide to 1080 pixels high. The upper limit of the file size for gif avatars is 50 mb, as I found out when I tried to convert the entire Shelter music video by Porter Robinson into an avatar and I couldn't compress it even to twice the maximum size. But for many users, a poor internet connection causes the gif to not load properly, and the Discord server gets a damaged gif file that it can't play. Sometimes, the Discord server considers the gif as an image when it is loaded from the camera roll, so uploading it as a file solves the problem. In some cases, your profile doesn't sync correctly with the Discord server, so gifs don't work or upload and cause problems.
Turn on “Automatically play gifs when possible” in the Discord settings to automatically play gifs. If you're trying to upload a gif as an avatar, make sure you have at least one Discord Classic subscription. If you use a messaging program like WhatsApp (which now supports GIFs and videos on Android), make sure that both users use the same version of the application.

If, for some reason, the gifs don't play if you upload them from the camera roll, try uploading the gifs as a file.
There's also a premium paid version of Discord called Discord Nitro, which offers all sorts of cool boosters like custom emojis, animated avatars, and more. Another thing to keep in mind is that Discord can't crop gif avatars to a square like it does (if I remember correctly) for normal images. WhatsApp does not send the message as a GIF image, in fact, the message is sent as a video itself and since the video is short, it actually plays it in a loop on the screen, which looks like a GIF animation without sound. This means that if your operating system settings have deleted the animation through, for example, the Windows settings, your gifs and Gif gestures will no longer play automatically. In that case, instead of uploading gifs from the gallery or internal storage, use a gif app like GIFY to upload or share gifs.
