Bilibili Video Downloader
Paste a Bilibili BV or av link and save the public video as MP4.
Quick answer
Bilibili Video Downloader saves public Bilibili videos as MP4 files. Bilibili serves DASH video and audio separately, so the tool merges the best publicly available pair into one file. Videos that need a logged-in account for their highest bitrate are saved at the public tier instead. Region-locked mainland content may fail from outside China. Finished files are removed after two hours.

Frequently asked questions
Can it save 1080p, 4K, or HDR tiers?
Only when those renditions are reachable without logging in. Bilibili often gates the highest bitrates behind an account, so the tool returns the best public tier.
Do bangumi and PGC episodes work?
Support is limited. Many bangumi episodes are rights-managed or region-locked, and those usually fail even when the regular video pages succeed.
Is the danmaku (bullet commentary) included?
No. Danmaku is a separate overlay stream, not part of the video file. The MP4 contains the picture and the normal audio track only.
Why does a Bilibili link fail outside China?
Some videos are licensed for mainland IP addresses only. A region-locked page returns an error before any media is exposed.
