Convert MOV to MP4
Turn an iPhone or Mac MOV into an MP4 that opens anywhere. If the video inside is already compatible, it's copied without any quality loss.
MOV and MP4 are boxes, not codecs
MOV (Apple's QuickTime format) and MP4 are both containers: they hold a video track, an audio track and timing information. MP4 was based on the QuickTime design, so the same H.264 or H.265 video fits in either. Converting between them is often just repacking, which is instant and lossless.
The catch is the codec inside. Recent iPhones record in HEVC (H.265) by default ("High Efficiency" in Camera settings). HEVC plays on Apple devices and many new phones, but not everywhere. For maximum compatibility, re-encode to H.264. See H.264 vs H.265 for the trade-offs and a live check of your browser.
Questions people ask
Is converting MOV to MP4 lossless?
Usually, yes. iPhone MOV files already contain H.264 or H.265 video and AAC audio, which MP4 can hold as they are. With "keep the picture exactly as it is" ticked, the tracks are copied into an MP4 container without re-encoding.
My iPhone video is HEVC. Will the MP4 play on Windows?
An HEVC (H.265) video stays HEVC after a lossless container change, and some Windows PCs and older Android phones can't play HEVC. Untick "keep the picture" and SqueezeVideos will re-encode it to H.264, which plays everywhere.
Why is the MOV so big?
Phones record at high bitrates so you can edit later. Re-encoding to H.264 at a sensible bitrate, or to a target size, often makes the file much smaller. The tool shows the real difference.
Can I open MOV files from a camera or screen recorder?
Most MOV files with H.264 or HEVC video open fine. ProRes files open only where the browser can decode ProRes, which is rare; the FFmpeg fallback may still read them on a computer.
