5. Why Does My Downloaded Bilibili Video Have No Audio or Sound?
This is the #1 most common issue users encounter when trying to download videos from Bilibili.
The Cause: In 2018, Bilibili transitioned from progressive FLV video files to modern DASH (Dynamic Adaptive Streaming over HTTP) streaming architecture. Under DASH, the video stream and the audio stream are transmitted as two completely separate files stored on different CDN endpoints.
When a standard video downloader attempts to grab the video link, it only downloads the video track, resulting in a completely silent MP4 file.
The Fix: Use our dedicated Bilibili to MP4 Downloader. Our engine retrieves both the highest-quality video stream and the matching high-bitrate AAC audio stream simultaneously, merges them into a single standard MP4 container without re-encoding quality loss, and delivers a file with 100% synchronized sound.

6. How to Download from Bilibili b23.tv Mobile Share Links
When sharing a video from the Bilibili mobile app, the generated URL often looks like https://b23.tv/AbCdEf.
Many generic downloaders reject b23.tv links because they cannot resolve HTTP 302 redirects or extract query tokens.
With BilibiliDownloader.co, you don't need to do anything special:
- Paste the b23.tv shortlink directly into our downloader box.
- Our backend securely resolves the redirect destination, validates the canonical bilibili.com/video/BV... target, and strips tracking parameters.
- All stream options and quality tiers load automatically within seconds.
7. Understanding Bilibili Resolutions, Qualities & Codecs (AVC, HEVC, AV1)
Bilibili encodes video in multiple codecs and quality tiers. Here is what each option means for your downloads:

|---|---|---|---|
| 8K UHD (4320p) | Ultra High Definition | AV1, HEVC | High-end PC / M-series Mac |
| 4K UHD (2160p) | Ultra High Definition | AV1, HEVC, AVC | Modern TV, iPad, PC, Mac |
| 1080p 60FPS | High Framerate Full HD | AVC (H.264), HEVC | All smartphones & computers |

Answers to Common Questions
Frequently Asked Questions
Why does my downloaded Bilibili video have no audio or sound?
Bilibili stores modern high-definition video (1080p, 4K, 8K) and audio tracks as separate DASH streams on its edge servers. If you use a basic downloader or browser inspect tool, you only receive the silent video track. BilibiliDownloader.co automatically merges the high-definition video stream and the high-bitrate audio stream into a single standard MP4 container so your download has crystal-clear synchronized audio.
How do I download Bilibili videos on an iPhone or iPad to my Camera Roll?
Open the Bilibili app or Safari, copy the video or b23.tv link, and paste it into BilibiliDownloader.co in Safari. Tap "Fetch streams", select your preferred MP4 resolution, and tap Download. When prompted by Safari, confirm "Download". Once finished, tap the Safari Download Manager icon, tap the file to open it in the iOS Files app, tap the Share button in the bottom-left corner, and select "Save Video" to transfer it directly into your iPhone Camera Roll.
How can I download videos from Bilibili b23.tv mobile shortlinks?
In the Bilibili mobile app, tapping the Share button generates a shortlink like https://b23.tv/xxxxxx. You do not need to convert or expand this link manually. Simply paste the raw b23.tv URL directly into BilibiliDownloader.co. Our server safely resolves the redirection target, parses the underlying BV identifier, and fetches all available video and audio streams instantly.
Can I download Bilibili videos in 1080p 60FPS or 4K for free without logging in?
BilibiliDownloader.co retrieves all publicly accessible stream tiers provided by Bilibili CDN servers. Standard public streams include 1080p, 720p, 480p, and 360p. For videos where higher quality streams (1080p 60FPS, 4K UHD, 8K) are publicly available, our tool extracts and merges them with lossless audio. No registration or personal account credentials are required.
How do I convert a Bilibili video directly into an MP3 song or podcast?
Paste the Bilibili URL into BilibiliDownloader.co and switch to the "Audio" tab in the results. Click "Preview" to listen in your browser, then click "Convert to MP3" (for universal 320kbps MP3 playback) or "Extract M4A" (for original lossless AAC audio). You do not need to download the full video file to get the audio.
How do I watch downloaded ASS Danmaku bullet comments with my video?
Download the MP4 video and the ASS subtitle file from our Danmaku tab. Place both files in the same folder with the exact same base name (e.g. video.mp4 and video.ass). Open the video in PotPlayer, VLC, IINA, or MPV. The player will automatically render the scrolling bullet comments over your video in real time.
