FAQ

Is this a free MOV to MP4 converter?: Yes. You can convert MOV to MP4 here without signing in or paying. There is no login wall and no usage meter in this page.
Do I need to upload my video to change MOV to MP4?: No. Conversion happens in your browser with ffmpeg.wasm. The file stays on your device unless you choose to download the result.
Can I convert QuickTime to MP4?: Yes. QuickTime .mov files are the intended input. Pick your QuickTime movie and convert it to MP4 on this page.
Why did remux fail and fall back to re-encode?: Some MOV files use codecs that cannot sit in an MP4 container with a simple stream copy. When that happens, the tool re-encodes video to H.264 and audio to AAC so you still get a playable MP4.
Does the page store my history?: No. There is no history, cloud account, or server-side storage. Closing or refreshing the page clears the in-memory result.
