Questions

No. The browser reads and converts it on your device. Only the static converter files are requested by the page.

MP3 is the most widely compatible. WAV is much larger and uncompressed. M4A is compact AAC audio.

No. The result is a separate audio file; the original video is not edited.

Browser conversion needs memory for the source, working data and result. Close other tabs or use a shorter file if the device runs out of memory.

Background

Choose one video and the sound is written into a new audio file in this tab. The original is not changed and no server receives it.

The video is copied into an in-browser conversion worker, and only its audio track is written to the result.
The same converter is shared by the other Video tools, so a second conversion in the same visit can reuse it.
