Facebook Feed vs Reels strategy
Facebook's algorithm has heavily shifted toward Reels since 2022. Short vertical videos (9:16, under 90 seconds) get significantly more organic reach than traditional landscape Feed posts. If you're creating video content for Facebook, Reels is where the distribution is.
Traditional Feed videos still work for longer-form content, tutorials, and content where your existing followers are the primary audience.
Square video (1:1) in the Feed
A well-known Facebook optimization: 1:1 square videos take up more vertical space in the mobile feed than 16:9 landscape videos. More screen real estate means more visibility. Studies consistently show square videos getting 20-40% higher engagement than landscape in Facebook Feed.
Facebook Messenger video
The 26MB Messenger limit affects a lot of people sharing videos in group chats. Use our Email preset (targets 23MB) or set a custom 25MB target, this will comfortably fit within Messenger's limit while keeping reasonable quality.

Why compress video before sending on Facebook?
Facebook enforces a strict file size limit. If your video exceeds it, Facebook will either reject the upload, reduce quality automatically, or convert it to a document file that recipients must download manually.
By compressing with CompressYourVideo.combefore uploading, you control the quality. Our tool calculates the optimal bitrate for your specific video length, so you get the sharpest possible result within the platform's limit.
