Supports .mov / QuickTime filesAbout MOV to MP4 conversion
MOV is Apple's QuickTime file format, commonly produced by iPhones, iPads, and Mac cameras. While MOV plays natively on Apple devices, it is not well supported on Windows PCs, Android devices, or many social media platforms. Converting to MP4 with H.264 encoding solves this compatibility problem.
This converter uses libx264 and AAC audio — the most compatible encoding for MP4. All processing is done locally in your browser; your video file is never uploaded to any server.
Frequently Asked Questions
- Why convert MOV to MP4?
- MOV files from iPhones and Macs do not play on many Windows programs, Android devices, or social media platforms. MP4 is universally supported everywhere.
- Will I lose video quality?
- Some re-encoding quality loss is unavoidable, but at the medium preset the difference is minimal for most viewers. Use the slow preset for the best quality-to-file-size ratio.
- Can I share the output on WhatsApp, Instagram, or TikTok?
- Yes. MP4 with H.264 is accepted by all major social and messaging apps.
- Is my video kept private?
- Yes. The entire conversion runs in your browser — nothing is uploaded to any server.
- What browsers are supported?
- Chrome and Edge work best. Recent Firefox versions also work. For Safari, ensure you have a recent version of macOS.
