A MOV or QuickTime file
- Takes
- MOV files holding H.264, HEVC, VP9, or AV1 video. ProRes and other editing codecs are read but cannot be rewrapped into MP4 — they are refused by name rather than half-converted.
- Size
- Any size. Nothing is rebuilt, so even huge files take seconds.
Your files stay on your device
How to use it
Drop a MOV video here to turn it into an MP4 in a moment, with no quality lost — perfect for iPhone videos. Your video stays on your device.
iPhone videos and QuickTime recordings are saved as MOV, which some websites, apps, and Windows programs won’t accept. MP4 works almost everywhere.
Drop your MOV onto the box above. There are no settings, because nothing about the video changes: same quality, same size. It’s done in a moment, even for big files.
Portrait videos stay portrait.
Want a smaller file instead? Use Compress Video.
FAQ
Does it lose quality?
No. The video is copied exactly — nothing is rebuilt.
Why is it so fast?
MOV and MP4 usually hold the same video. It’s more like changing the label than converting.
Will the file get smaller?
Barely. To make it smaller, use Compress Video.
Why was my MOV refused?
It probably uses a professional editing format (like ProRes) that MP4 can’t hold. Use Compress Video to convert it.
Will my portrait video stay portrait?
Yes.
How big a MOV can I convert?
Any size.
How it worksFor the curious
MOV and MP4 are both built on the same underlying container format, and an iPhone .mov almost always holds the same H.264 video and AAC audio an .mp4 would. The packets are read out of the QuickTime container and written into MP4 without decoding a frame — verified bit-for-bit by comparing the extracted streams. A 6 MB clip converts in about 10 ms here, and time scales with file size.
File size changes by well under one percent, from how the index is packed. Phones store portrait video as landscape frames plus a rotation instruction in the container; it is carried across so the video does not play sideways.
Some camera and editing MOVs hold ProRes or another editing codec an MP4 cannot carry; those are refused by name with a pointer to the compressor. Unsupported audio is dropped with a warning before you start.
