Steps
- Install Video Compressor for Mac from the Mac App Store.
- Drag your video into the app or click Add Files.
- Select a preset (1080p/720p) or set a custom bitrate to reduce size.
- Preview quality and click Compress to export.
Why this works
Re-encoding with efficient settings and optional downscaling is the most reliable way to shrink file size without a visible drop in quality.
Smart starting points
Try 1080p for general sharing or 720p for messaging. Then adjust bitrate in small increments while comparing the live preview to keep detail while shrinking size.
Compatibility vs. size
For broad compatibility across devices and browsers, use settings that align with widely supported formats. Higher efficiency settings can reduce size further where supported—use the preview to choose the best trade‑off.
