Copy the stream, or re-encode it
H.264 and HEVC video copy into the MP4, and so do AAC and MP3 sound. Copying reads the container and writes a new MP4. It leaves the encoded pictures untouched, so it runs even in a browser that has no HEVC decoder. ProRes, PCM and other codecs are re-encoded with the browser's video encoder into a codec the MP4 plays widely, usually H.264 and AAC.
A tick for H.264 asks the page to re-encode HEVC so the file plays where HEVC is missing. That step needs a browser that can decode the original video: Safari, and Chrome, Edge and Firefox where the system provides an HEVC decoder. Rotation from the phone is kept.

Questions
Will an iPhone video keep its quality?
An iPhone MOV is usually H.264 or HEVC with AAC sound. Both copy into the MP4, so the picture and the sound stay as they were.
When does the page re-encode?
ProRes, animation codecs and uncompressed sound are re-encoded so the MP4 plays widely. You can also ask for H.264 when the source is HEVC.
Does the picture keep its rotation?
Yes. A copied file keeps the rotation from the phone, and a re-encoded file is written upright.
Which browsers convert MOV files?
Chrome, Edge and Safari on a computer or a phone, and Firefox on a computer, re-encode when a track needs it. Copying H.264, HEVC, AAC or MP3 runs wherever the page can read the file, including a browser with no video encoder.
