Why Convert MOV to MP4?
MOV is Apple's QuickTime format, while MP4 is universally supported across all devices and platforms. If you've recorded videos on an iPhone or Mac, you likely have MOV files that need converting for wider compatibility.
Key Differences Between MOV and MP4
| Feature | MOV | MP4 | |---------|-----|-----| | Compatibility | Apple devices | All devices | | File Size | Larger | Smaller | | Quality | Excellent | Excellent | | Streaming | Limited | Universal |

Method 1: Online Conversion (Fastest)
The easiest way to convert MOV to MP4 is using an online converter like ConvertIntoMP4:
- Upload your MOV file - Drag and drop or click to select

This method requires no software installation and works on any device with a browser.
Method 2: Using FFmpeg (Advanced)
For batch conversions or command-line workflows, FFmpeg is the industry standard:
ffmpeg -i input.mov -c:v libx264 -c:a aac output.mp4
Recommended Quality Settings
For the best quality-to-size ratio, use these settings:
ffmpeg -i input.mov -c:v libx264 -crf 23 -preset medium -c:a aac -b:a 128k output.mp4
- CRF 23 - Balanced quality (lower = better quality, larger file)
- Preset medium - Good encoding speed
- AAC 128k - Standard audio quality

Quality Tips
- Avoid multiple conversions - Each conversion can reduce quality
- Match original resolution - Don't upscale unnecessarily
- Use hardware encoding - Faster processing with GPU support
- Check audio sync - Some conversions can cause drift
Common Issues and Solutions
Video plays but no audio
This usually means the audio codec isn't compatible. Re-convert with AAC audio:
ffmpeg -i input.mov -c:v copy -c:a aac output.mp4
File size is too large
Increase CRF value (e.g., 28 instead of 23) or reduce resolution.
Conversion is slow
Use a faster preset like -preset fast or enable hardware acceleration.
