Local video compression
Compress video on Mac without uploading it
Make an MP4 or MOV easier to share by reducing its resolution or quality on your own Mac.
How to make a video smaller
- Add the video. Open Video Converter 1-Click and select the file you want to reduce.
- Choose output settings. Select a lower resolution, a lower quality preset, or both. MP4 is a practical choice for sharing.
- Convert and compare. Check the new file size and watch the result before replacing the original.
What changes file size?
Resolution
Reducing 4K to 1080p or 1080p to 720p often makes a substantial difference.
Quality
Lower quality uses less data, but aggressive settings can introduce visible artifacts.
Duration
Trim unwanted footage first so the converter does not spend space encoding it.
For email: attachment limits differ between providers. The app offers quality and resolution presets rather than an exact target-size control, so check the finished file before attaching it.
