About the Bilibili Audio Downloader
Bilibili hosts a huge library of original video — anime commentary, music covers, tutorials, and creator uploads that often carry a soundtrack or voiceover worth keeping. The Bilibili Audio Downloader extracts the sound from any public Bilibili video as a clean MP3, so you can save a cover, a lecture, or a track you have the right to reuse.
It works with standard bilibili.com/video/BV… links and short b23.tv links alike, running entirely server-side — no Bilibili account, no browser extension, and nothing stored after your download finishes. Please only download audio you own or are licensed to use.

Pro Tips for Bilibili Audio Downloader
Get the most out of your audio downloads with these expert tips.
Use the Video Link, Not the Channel
Copy the link to a specific video (it contains /video/BV…), not a user's channel page, which has no single video to extract.
b23.tv Short Links Work
Short b23.tv links from the Bilibili app are resolved automatically to the full video.
Public Videos Only
Region-locked or members-only videos can't be accessed by any tool, including this one.
BV and AV IDs
Modern Bilibili links use a BV id (e.g. BV1xx411c7mD); older av-number links may need to be opened once on Bilibili first to get the current BV link.
