Why convert MOV to MP4?
MOV is Apple's QuickTime container, and while it plays perfectly on iPhones and Macs, it regularly causes trouble on Windows PCs, Android phones, older smart TVs, and many web platforms. MP4 uses the same underlying compression in most cases, so converting is usually fast and loses little to no quality - you get a file that plays everywhere, often at a similar size.
MOV
MOV is the QuickTime File Format container developed by Apple. iPhones, iPads, and Macs record video as MOV by default, typically holding H.264 or HEVC video with AAC audio.
MP4
MP4 (MPEG-4 Part 14) is the most widely supported video container in the world. It is the safe choice for sharing, uploading, editing on any platform, and playing on any device made in the last 15 years.
Frequently asked questions
Will converting MOV to MP4 reduce quality?
Usually not noticeably. MOV and MP4 are closely related containers and often carry the same H.264 video stream. When the streams are compatible the conversion is mostly a repackaging job, so visual quality is preserved.
Why does my MOV file not play on Windows?
Windows Media Player and many Windows apps lack full QuickTime support, especially for HEVC video recorded by newer iPhones. Converting to MP4 with H.264 video resolves this in almost all cases.
Is my video uploaded to a server?
No. muxTools runs FFmpeg and WebCodecs-based engines compiled to WebAssembly inside your browser. The file is read locally, converted locally, and never transmitted.
