Hi, I'm dark. I built Audio Tools for turning a supported local MP4 into an MP3 without sending the video to a server. It shows the track details before conversion and lets you preview the result before downloading. The current version handles one file at a time, with the limits listed on the page. If you try it, I'd be interested in which browser you used and whether the conversion and saving steps worked for you. Please avoid sharing private media in feedback.
