Compress video for Messenger
Send a video directly in Messenger and anything over about 25MB stalls and won't go through. Compress under 25MB first and it sends as a normal attachment; if the video is large and you want original quality, then consider a cloud link (Drive / OneDrive). The tool above is preset to 25MB.
Quick answer
Facebook Messenger caps a video sent as a direct attachment at about 25MB; above that it won't send and you have to compress or switch to a cloud link. ConvertMeow shrinks your video under 25MB locally in your browser — no upload, no watermark — and short clips almost always fit.
Shrink your video to 25MB
Target size
Derives a bitrate from target size ÷ duration and re-encodes; best for short clips.
Messenger's video limit
A video sent as a direct attachment caps at about 25MB, on both mobile and desktop. Above that, Messenger won't send it directly — you need to compress, split it, or use a cloud share link.
Messenger also re-compresses what it receives, so compressing to a sensible size and keeping it sharp before uploading produces a better result than letting it crush the file.
- Send directly: compress to ≤25MB.
- Large video, original quality needed: upload to cloud and share a link.
- Trim to the key segment first for better quality.
Still blurry at 25MB?
Longer videos look soft at 25MB. Trim to the few seconds that matter first so the bitrate is spent on the key footage; for long clips where quality is critical, use a cloud link instead.
