16 MB is a short clip's worth of good video: enough for a few seconds at full HD or a minute or so at lower resolution. This page works out the bitrate the video needs to land under 16 MB and picks the largest picture that bitrate carries cleanly, so it fits on the first try instead of by trial and error.
Common clips at 16 MB
A 15-second clip: fits at 1080p.
A 30-second clip: fits at 1080p.
A one-minute video: fits at 720p.
A five-minute video: fits at 240p.
A half-hour recording: too long to fit and stay watchable; trim it first.
Where this limit comes up
Sixteen megabytes was the limit WhatsApp put on videos for years, and many messaging and ticketing systems kept the figure.
How long a video fits in 16 MB
At 1080p: about 40 seconds.
At 720p: about 85 seconds.
At 480p: about 3 minutes.
Screen recordings, slides and anything with little movement go further than camera footage.
If it is too long to fit
Trim it first with Trim Video. Halving the length halves the size, which no quality setting can match, and a shorter clip keeps a sharper picture.
Questions
How do I compress a video to 16MB?
Add it here and press the button. The bitrate is worked out from the video's length so the MP4 comes in under 16 MB, usually in one pass.
Will it still look sharp?
For a clip that fits at 720p or above, yes. A video much longer than the lengths above has to drop to a smaller picture to fit.
Does it add a watermark?
No. There is nothing to sign up for and nothing is added to the video.
