Understanding LinkedIn Video Specs
You should know LinkedIn’s upload specifications before uploading a video to the platform.
Supported Video Formats
First, you should know what video file types LinkedIn supports to avoid incompatibility issues. All in all, this platform can handle multiple popular video formats, such as MP4, WebM, WMV, MOV, AVI, M4V, MPG, etc.
File Size Limits
LinkedIn allows uploading videos of up to 5 GB in size to regular posts. This is a very generous file size limit. However, you’d better keep your file in a smaller size for quick uploads and smooth playback.
Aspect Ratio
LinkedIn accepts multiple forms of videos, and the recommended aspect ratios vary by content type or your device. For instance, use 1:1 for square posts, 4:5 for vertical videos on desktop, 16:9 for feed posts, and 9:16 for mobile-specific content.
Resolution
LinkedIn supports resolution from 256×144 to 4096×2304 pixels. To ensure the user experience and video quality, use a resolution that matches your content aspect ratio to avoid black bars.
