How do I convert MOV to MP4?

Is this MOV to MP4 converter free?
Yes. This converter is free to use, with no account, subscription, or ads.
Are my MOV files uploaded?
No. Conversion runs locally in your browser, so your media file stays on your device.
What happens when converting MOV to MP4?
The converter moves the video and audio from the MOV file into an MP4 file. When your browser supports it, H.264 and HEVC video is copied without re-encoding, so picture quality is unchanged, and audio is converted to AAC when needed. HEVC video from recent iPhones stays HEVC, which some older players cannot open.
Which browsers and devices support MOV to MP4 conversion?
The converter works in current desktop browsers on Windows, macOS, Linux, and ChromeOS. Performance depends on file size and device hardware.
