Changing the picture uses your browser's own video encoders. Recent Chrome and Edge can write H.264, VP9 and AV1; Firefox and older Safari lack some encoders, so the tools offer only what your browser can produce and say so when something is missing.

Questions
No. Everything runs in your browser on your own device, and the video is never uploaded.
Not when the video's codec is one the new format supports. Then the picture is copied as it is, which is fast and loses nothing. If you pick another codec, or the format cannot hold the original one, the picture is re-encoded and loses a little quality.
Your browser has to be able to encode video for changes to the picture. Browsers differ in what they can encode, so a recent Chrome or Edge is the safest choice. The tool tells you when it cannot make the format you picked.
