Convert MOV to MP4.
Make QuickTime MOV clips play everywhere as MP4. Fast remux with ffmpeg, quality preserved.
MOV vs MP4 — usually just a repackage
MOV and MP4 are both containers — wrappers around a video and audio stream. MOV is Apple's QuickTime format; MP4 is the universal one. The catch is that they very often hold the exact same H.264 (or H.265) video inside, which is what makes this conversion so quick.
Often completely lossless
When the MOV's codec is already MP4-compatible, the audio and video streams are copied straight into an MP4 container without being re-encoded — fast, and with no quality loss at all. If the source uses an Apple-specific codec like ProRes, it's re-encoded at high quality instead.
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, no watermark, no daily cap.
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?+
Usually it's identical. MOV and MP4 commonly hold the same H.264 video, so the stream is copied into the new container without re-encoding — zero quality loss. Only an incompatible codec (like ProRes) needs a high-quality re-encode.
