What’s the Buffer Video Size Limit?
As we mentioned above that Buffer supports uploading videos to multiple social media platforms. But did you know that Buffer has a size limit for uploading videos? When you use Buffer to send videos to various social platforms, you need to pay attention to the size of the video.
Buffer has a limit on the size of uploaded videos. However, the limit is different for each social platform. For example, the size of Instagram videos cannot exceed 100MB, while the size of YouTube Shorts videos can be up to 10GB.
The specific Buffer video size limits for uploading to various social media are as follows:

If the video you want to upload exceeds Buffer’s video size limit, it’s best to reduce its size before uploading. Also, pay attention to the video formats Buffer supports:
- X (Twitter), Facebook, LinkedIn, and Pinterest: MP4, MOV, AVI, and M4V.
- TikTok: MOV, MP4, and WebM.
- Instagram and Threads: MP4 and MOV.
