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.
WebP, wherever it is shown in a browser: full colour instead of 256, and a much smaller file for the same clip. Make a GIF when the loop has to show in email or an older app; the video to GIF tool does that.
An animated image is stored frame by frame, without the tricks a video codec uses, so long clips get very large and use a lot of memory in the tab. Use the trim under More options to pick which 30 seconds, or keep a longer clip as MP4.
480 pixels wide at 15 frames a second unless you change them under More options. That suits a product shot or an interface demo. Go up to 640 pixels for small text, down to 10 frames a second for a smaller file.
It is dropped. Animated images have no audio track.
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.
