Merge videos
Combine two or more videos into one, in the order you choose. Matching clips are copied without re-encoding.
Drop the videos to join
Two or more MP4, MOV, WebM or MKV files. You can change the order next. Up to 1.0 GB per file.
Runs in your browser. Your files are not uploaded.
Large videos can run out of memory on phones.
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
Only when they have to be. When every video has the same codecs, size and frame rate, they are copied without re-encoding, which is fast and loses nothing. Otherwise every frame is re-encoded, and videos of another shape get black bars.
The format and size of the first video.
No. Everything runs in your browser on your own device, and the video is never uploaded.
