MOV vs MP4
MOV and MP4 are both containers: wrappers around a video and audio stream. MOV is Apple's QuickTime format; MP4 is the universal one. A MOV can hold anything from H.264 to HEVC to ProRes, and not every player, browser or upload form copes with all of them.
What the conversion does
Whatever is inside your MOV, the video is re-encoded to H.264 and the audio to AAC, the combination virtually every phone, TV, browser and editor plays. That takes longer than simply repackaging the streams, and like any re-encode it is a new compression pass rather than an exact copy, though at ffmpeg's standard quality setting the difference is hard to see at normal viewing sizes.
Why bother
MOV plays beautifully on Apple devices but trips up some Windows tools, web players and upload forms. MP4 is the safe, plays-everywhere choice, and once it's an MP4 you can pull the audio with MP4 to MP3 or send it to TranscriptAI for a transcript.

MOV to MP4: transcode
MOV and MP4 are container/codec formats, so this re-encodes the video (a lossy step. Start from the best source you have). MP4 is broadly compatible, which helps when a player, editor or site won't accept MOV.

Common questions
Is it free?+
Yes. Convert MOV to MP4 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Will quality hold up?+
For normal viewing, yes, but it is not a bit-for-bit copy. Every MOV is re-encoded to H.264 video with AAC audio at ffmpeg's standard quality setting, so the MP4 is a fresh compression of the original. Keep the MOV if you need the untouched source, for example for further editing.
