Convert MOV to MP4
A video from an iPhone or a Mac will not upload, will not play on an Android phone, or gets rejected by an ad platform that wants MP4.

Where the streams already fit the target container this is a lossless remux, which is close to instant. Otherwise it re-encodes, which in a browser is slow — keep it under a few hundred MB and send long videos to the cloud engine.

What actually changes
MOV and MP4 are not the same picture in two wrappers.
MOV and MP4 are close relatives, both built on the ISO base media file format. When the video is already H.264 with AAC audio, this is a remux: the streams are copied into a new container with no re-encoding and no quality loss at all.
Worth knowing first
It stops being a remux the moment the MOV holds something MP4 cannot carry. ProRes and Apple Animation footage from a Mac editing workflow has to be fully re-encoded, which is slow and lossy, and it is why a 4 GB MOV sometimes becomes a 200 MB MP4.
Questions
MOV to MP4, answered
Will I lose quality?
Not if the streams are copied. Only a genuine re-encode, forced by an incompatible codec, costs quality.
Why does my iPhone video not play on Windows?
Recent iPhones record HEVC by default, and Windows needs an HEVC extension for it. Converting to H.264 in MP4 removes the dependency.
Does the conversion run in my browser?
No. Video transcoding runs on the SafeConvert engine. Your file is deleted the moment it finishes.

Instant, because the file never went anywhere. Nothing expires, since nothing was stored.
