MOV to MP4 Converter
Converts Apple QuickTime MOV files to universally compatible MP4 format. MOV is Apple's native video format used by iPhones, iPads, and Mac cameras. While MOV and MP4 share similar codecs, MP4 has broader compatibility outside the Apple ecosystem.
What is it used for?
- Sharing iPhone and iPad recordings with Android and Windows users
- Uploading Mac screen recordings to non-Apple platforms
- Making QuickTime videos playable on Windows PCs and smart TVs
- Social media platforms that prefer MP4 over MOV
- Cross-platform video editing workflows
Step-by-Step Guide
- Click upload or drag and drop your MOV file (from iPhone, Mac, etc.)
- Adjust quality settings in the settings panel
- Click 'Convert to .MP4' to start
- Preview the converted video
- Download the MP4 file ready to share anywhere
How it works
Upload a MOV file. FFmpeg transcodes to H.264/AAC with the faststart flag enabled for optimized web streaming. The faststart flag moves metadata to the beginning of the file, allowing playback to begin before the full download completes.
Tips & Best Practices
- iPhone 4K recordings can be large (300-500MB/min) - expect longer conversion times
- MOV files from professional cameras (ProRes) will be re-encoded, resulting in smaller but slightly lower quality files
- The faststart flag is automatically applied for web-optimized output
Frequently Asked Questions
Is MOV the same as MP4?
They're similar but not identical. Both can contain H.264 video, but MOV is Apple's container format while MP4 (MPEG-4 Part 14) is an international standard. Some MOV files use Apple-specific codecs (ProRes, HEVC) that require conversion.
Will my iPhone video quality be preserved?
Yes, with the default CRF 23 setting, quality is virtually identical. iPhone videos are typically H.264 or HEVC, both of which FFmpeg handles well.
What is faststart?
The faststart flag moves the file's metadata (moov atom) to the beginning, enabling progressive playback. This means web browsers can start playing the video before the full file downloads.
Privacy & Security
This tool uses FFmpeg compiled to WebAssembly (WASM). The WASM binary (~25MB) is downloaded from a CDN on first use and cached by your browser. All file processing happens locally on your device - your files are never uploaded to any server. This makes it safe for sensitive, private, or confidential media files. Large files may take longer to process depending on your device's CPU and available memory.
