Sometimes you do not need the video — just the audio. Lectures, podcasts, music covers and audiobooks on Bilibili can all be converted to MP3 in seconds, free.
Why convert to MP3?
- Much smaller files than video (roughly 10x smaller).
- Perfect for music, podcasts and lectures.
- Plays on every device.
Step-by-step
- Copy the Bilibili video URL or BV number from the app or website.
- Go to bbvideosaver.com and paste it into the download box.
- Click download and wait for processing to finish.
- Select MP3 from the format list.
- Save the audio file to your device — done in seconds, no sign-up, no watermark.
Quality notes
The MP3 is extracted from the video’s original audio track, so quality matches the source.
For the smallest files, MP3 is ideal; MP4 is better when you need the visuals too.
