Bilibili Video Download: BV, av and b23.tv Links

Bilibili stores most videos as separate DASH video and audio streams, so this page shows what the provider can reach without logging in as you.

Support status

The provider lists this platform in its documented supported sites. Nothing here has been verified end to end yet, so results are best effort.

Bilibili is the largest video community in mainland China, and it addresses videos by a modern BV string, a legacy av number, or a b23.tv short link that expands to the full watch page. This tool accepts any of the three.

Resolution above 1080p is normally gated on Bilibili itself to signed-in, often premium, accounts, and this tool never signs in on your behalf. What you see here is exactly what an anonymous request can reach.

How it works

  1. Step 1

    Copy the Bilibili link

    Open the video on bilibili.com or in the app and copy the link. A full watch URL, a b23.tv short link and a bare BV id all work; playlist pages do not.

  2. Step 2

    Paste it and resolve

    The server expands any b23.tv redirect, extracts the BV or av id and rebuilds a canonical watch URL before requesting the stream inventory from the provider.

  3. Step 3

    Pick the streams you need

    DASH entries list picture and sound separately. Take the video stream you want and the matching audio track, then combine them locally if the file arrives silent.

What this tool actually does

BV, av and short links

Bilibili identifies the same video in several ways. The parser accepts the BV string, the legacy av number and b23.tv share links, then rebuilds a canonical URL before any request leaves the server.

DASH streams named honestly

Higher-quality Bilibili video is delivered as separate video and audio streams. The format list labels every row as video-only, audio-only or muxed rather than pretending each entry is a complete file.

No login on your behalf

This tool never signs in to your Bilibili account. Anything the platform gates behind a login, such as premium quality tiers or paid content, stays out of reach and is reported as unavailable instead.

Limits and responsible use

  • Video above 1080p is normally gated to a signed-in or premium Bilibili account, so those tiers do not appear here.
  • Download links the provider returns expire within minutes, and a fresh link is requested each time you press download.
  • Only download video you own or have the uploader's permission for; re-uploading someone else's clip can breach copyright and platform rules.

Bilibili Video Download questions

Can I download Bilibili video above 1080p?
Normally not from here. Bilibili gates higher quality tiers behind a signed-in account and often a premium subscription, and this tool deliberately does not sign in for you. The format list shows only what the provider can reach anonymously.
What is the difference between BV and av ids?
They identify the same video in two generations of Bilibili numbering. Older links and archived pages use av numbers, newer ones use BV strings, and this page accepts either before converting the link to a canonical watch URL.
Will I get one file with picture and sound?
Sometimes. Progressive formats arrive with audio already muxed. Most higher-quality Bilibili streams are DASH, so picture and sound are separate; download both and combine them locally with a tool such as ffmpeg.

Bilibili and Weibo are handled by the same parser as everything else. WeChat Channels, WeChat articles and Doubao are not supported by the configured provider, and those pages explain why instead of showing a dead button.
