Reducing size is compression
Searchers often say reduce video size, shrink video, or make video smaller. In practice, the tool lowers bitrate and resolution to create a smaller MP4 file.
Best settings and limits
Best first try
Start with Balanced and 720p. If the result is still too large, run again with Smallest file or 480p.
When this may fail
Long videos and high-motion footage need more bitrate. A short clip can shrink much more cleanly than a long recording.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
Frequently asked questions

Will my video be uploaded?
No. The selected video is processed in this browser tab.
How do I make it even smaller?
Choose a lower resolution or stronger compression, or trim the video before compressing.
