No. Everything runs in your browser - your file never leaves your device. How this is verifiable
AVI (Audio Video Interleave) is Microsoft's aging container from the early 1990s - still found today in old DivX/Xvid rips, archive videos and surveillance recordings. The video content often needs an old codec, but the audio track itself is usually straightforward PCM or MP3 and can be extracted directly.
The tool demuxes the AVI container, drops the video track (-vn) and encodes the audio track with libmp3lame to MP3 at the chosen bitrate - regardless of which video codec sits in the same container, because only the audio track is read.
This lets you save, for example, the commentary or music of an old archive video as a handy MP3, without keeping the often bulky and outdated video file. Everything runs entirely locally in the browser.

Limitations: Only the audio track is read - whichever video codec sits inside the AVI does not matter and is not converted along. If the file contains no readable audio track, the tool reports that honestly instead of producing an empty file. One file per run.
No, the entire extraction runs locally in your browser.
No - for audio extraction only the audio track is read, the video codec (even a very old one) is not touched.
For a complete video conversion, use "Convert video" - this tool specifically pulls out only the audio track.
Many older archives, DivX/Xvid rips and some surveillance systems still use the container today.
