Worked example
Measured on our own 12 second H.264 MP4 at 1280 by 720, converted to MOV with ProRes picked under More options.

3.2 MB
MOV, ProRes 422
72.9 MB
ProRes stores every frame whole, which is why editors scrub it smoothly and why it is over twenty times the size. Left on Auto, the same file rewrapped to a 3.2 MB H.264 MOV in 6 seconds.
1. Add the MP4. 2. Choose the codec. 3. Convert locally. 4. Download the MOV.

Questions

No. The file is opened by the page and converted by ffmpeg compiled to WebAssembly, on your own machine. There is no upload step, and closing the tab discards everything.
No. Both are containers, and with fast mode the same H.264 video goes into the MOV untouched. The quality only changes if you re-encode, and then it is the codec and the quality setting that decide it, not the file extension.
When the file is going onto an editing timeline. H.264 stores most frames as changes from other frames, so an editor has to work hard to jump around in it. ProRes and DNxHR store every frame whole, so scrubbing and cutting stay smooth. The price is size: expect the file to be many times larger than the MP4.
Quality picks the flavour: Smaller gives ProRes 422 LT, Balanced gives ProRes 422, Best gives ProRes 422 HQ. The audio becomes uncompressed PCM, which is what editors expect beside ProRes.
An H.264 MOV plays in the Windows Media Player and Films and TV apps, and in VLC. ProRes and DNxHR need an editor or VLC.
500 MB and 10 minutes. Everything runs inside one browser tab, which has a fixed memory budget, and the encoder runs on a single thread. A rewrap takes seconds; a full re-encode runs at about real time for 720p and several times the clip length for 1080p. For anything bigger, a desktop encoder such as HandBrake is the better tool.
