Lower bitrate first
Bitrate is the main driver of video file size. Reducing it has the biggest effect, so start there and only lower resolution if the file is still too large.

Steps
Quick workflow
Use this simple browser workflow to get a smaller file while keeping the original on your device
- Select your video file.
- Choose MP4 output format.
- Pick a balanced preset or lower the bitrate.
- Reduce resolution to 720p if needed.
- Compress and verify the output is under 50MB.
What to know before you start
Use 720p for big savings
If the source is 1080p or 4K, exporting at 720p dramatically reduces size while staying sharp enough for most screens and sharing.
Local browser processing
The video is compressed on your device. Large files never leave your browser, which keeps private and client footage safe.

Can I compress a video to exactly 50MB?
File size depends on length, resolution and content. Lower bitrate and resolution iteratively; LessMB helps you approach the 50MB target.
Will quality drop a lot at 50MB?
For typical clips, 720p at a moderate bitrate looks very good and fits well under 50MB. Longer videos may need stronger settings.
