Why won't my iPhone MOV file play on my PC or Android?

MOV is Apple's proprietary container. Windows PCs without QuickTime installed and Android devices don't include a native MOV decoder. MP4 uses a universal standard that every device understands.

Does converting MOV to MP4 reduce video quality?

At high quality settings, the difference is minimal. If the MOV already uses H.264 video, the conversion is essentially a container swap with minimal re-encoding.

Are my files uploaded?

No. All conversion runs in your browser using WebAssembly. Files never leave your device.

Yes, completely free with no account required.
