DASH Audio-Video Demuxing
Bilibili delivers modern high-resolution video and audio as separate DASH streams on edge CDNs. Our engine merges them directly into a synchronized standard MP4 container without re-encoding loss.
02 · Processing
Where Processing Happens
Watermark removal runs in your browser through WebAssembly, and the edited file is not uploaded. Merging video and audio tracks and MP3 encoding run on our server, and temporary files are deleted when the job finishes.
03 · Data Handling

Frequently Asked Questions About Bilibili Video Downloader
Everything you need to know about downloading Bilibili videos, MP4 quality, MP3 conversion, b23.tv links, and legal safety.
Should I use this tool or yt-dlp?
yt-dlp is a free open-source command-line program that supports many sites and gives more control over formats and batch jobs, but it must be installed and needs FFmpeg to merge streams. BiliVideoDownloader runs in the browser with no install, which suits occasional downloads from a phone or a shared computer.
What is Bilibili Video Downloader and how does it work?
Bilibili Video Downloader is a free online tool that parses public Bilibili video links (bilibili.com, BV IDs, AV IDs, and b23.tv shortlinks) to extract and download high-definition MP4 videos, 320kbps MP3 audio, CC subtitles (SRT), and Danmaku comments (ASS) directly from edge CDNs.
How can I download Bilibili videos online for free?
Copy any public Bilibili video URL, paste it into the search box above, and click "Fetch streams". Choose your desired MP4 resolution (1080p, 4K, 8K) or MP3 audio and click Download. No registration or software installation is required.
Can I download Bilibili videos in 1080p 60FPS, 4K UHD, or 8K?
Yes! Our downloader retrieves every stream quality provided by Bilibili up to 1080p 60FPS, 4K Ultra HD, and 8K resolution, preserving original frame rates, AV1/HEVC/AVC video codecs, and lossless audio bitrates.
How do I download Bilibili videos with synchronized sound?
Bilibili delivers high-definition video and audio as separate DASH streams. BiliVideoDownloader automatically muxes the high-bitrate video and audio streams together into a single, synchronized standard MP4 container ready for immediate playback.
Can I download Bilibili videos without a watermark?
The file you get is the original video stream, so it has no player controls or page overlays. Logos that the uploader burned into the picture are part of the video itself and stay in the download.
How do I convert Bilibili videos to 320kbps MP3 audio?
Paste the video URL and navigate to the Audio tab. You can download the extracted audio track as high-bitrate MP3 or original lossless M4A (AAC) up to 320kbps without downloading the video payload.
Does the downloader support b23.tv mobile shortlinks and BV IDs?
Yes! The downloader automatically resolves mobile b23.tv share links, canonical desktop URLs (bilibili.com/video/BV...), raw BV strings (e.g., BV1xx411c7mD), and classic AV IDs (e.g., av170001).
Can I download Bilibili CC subtitles and Danmaku bullet comments?
Yes. You can export official closed captions (CC) as standard UTF-8 SRT or JSON files, and export scrolling Danmaku bullet comments in ASS format compatible with VLC and PotPlayer.
Does Bilibili Video Downloader work on iPhone, Android, PC, and Mac?
Yes. It works seamlessly across all modern browsers including Safari on iPhone/iPad, Chrome on Android, and Chrome, Firefox, Edge, or Safari on Windows, macOS, and Linux.
Can I batch download multi-part Bilibili series and course playlists?
Yes! When you paste a link to a multi-P video, course playlist, or anime series, our episode selector detects all parts so you can switch episodes or queue up to 8 parts for batch downloading.
Is BiliVideoDownloader.com free and safe to use?
It is free to use and needs no account or plugins. Merging video and audio and MP3 encoding run on our server, temporary files are deleted when the job finishes, and we do not host Bilibili media. Standard server logs and analytics may record technical data such as your IP address; see the Privacy Policy.
Is it legal to download videos from Bilibili?
Downloading videos for personal, educational, offline backup, and fair use is generally acceptable. Always respect creator copyright and intellectual property rights, and do not distribute or commercialize copyrighted material without authorization.
