How to
How to download videos
Install bilibili Video Downloader once, open any BiliBili video, and save it in a couple of clicks.

Play the video
Start playing any video on BiliBili.tv — the extension detects it in the background while you watch.
2
Pick a quality and download
Open the popup, pick the quality you want, and hit Download.

When the capture finishes, click play to watch it instantly or browse to its location on your disk.
Features
Everything bilibili Video Downloader can do
One extension covers the whole journey — finding the video, picking the quality, processing it locally, and saving a clean file to your disk. Built for sites other than YouTube.
Downloads and history
A download manager that behaves like one: fast, transparent about progress, and easy to search later.
Playable partial downloads
Long downloads become playable as soon as the first chunks arrive — start watching without waiting for the whole file.
Live streaming downloads
Start a capture on a BiliBili live broadcast and stop whenever you like — the result is a normal, seekable video file.
Pause, resume, salvage
Pause any download and resume it later from where it stopped; stopping keeps the partial file, so nothing already downloaded is wasted.
Parallel transfers
Up to ten downloads run side by side — you set the limit (1–10) in Settings.
Honest progress
Live size, speed, and percentage for every job — not a spinner and a shrug.
Pause & resume
Pause and resume any job; the queue keeps moving with the next file.
Completion alerts
Optional desktop notifications tell you when a capture finishes — handy for long downloads.
100-item history (default)
Recent downloads are kept in a searchable local list with the exact page and stream URL attached — the limit is yours (default 100, up to 1000).
Automatic cleanup
Set an age limit and old history entries quietly expire on their own.
Open file location
Jump straight to your download folder from Settings, or open any finished file from its history entry.
BiliBili.tv and muxing
The hard cases are where the extension does its best work.
Automatic audio muxing
On BiliBili.tv, the audio track is downloaded alongside the video and merged into one file — you never handle separate tracks.
Per-quality codec labels
Each resolution is listed with its codec, so you know exactly what you're saving before you commit.
Pure-JavaScript muxer
Merging happens entirely inside the extension — no FFmpeg, no codecs, nothing to install.
Interface
Calm, quick, and informative — the UI stays out of the way until you need detail.
Thumbnail previews
Every detected video shows its poster where the page provides one, so you know you have the right one before saving.
Media inspector
Resolution, codec, duration, and size are listed for each quality before you commit.
Title search
Find any detected video or past download by typing part of its title.
One popup, three tabs
Videos, Downloads, and Settings live together in one popup — open it any time to see what's on the page.
Four themes
System, Dark, Light, and Transparent — follows your system by default, override any time in Settings.
Resizable popup
Set the width from 360 to 720 px so long titles and file names fit.
Privacy and performance
Your browsing stays on your machine. There is no server in the middle and no analytics on the wire.
Local-only processing
Streams are fetched, muxed, and converted inside your browser. Nothing is uploaded to us — we have no servers to upload to.
Zero telemetry
No analytics SDK, no crash reporting, no identifier. The network panel stays quiet about bilibili Video Downloader.
Tiny footprint
The whole extension is about 2 MB and starts instantly.
Built-in muxer
Pure JavaScript handles all merging — you never install codecs or command-line tools.
Diagnostics built in
A log viewer with save, copy, and clear makes support issues reproducible without sending anything anywhere.
Resumable transfers
Paused or interrupted downloads resume from where they stopped, and expired links refresh automatically.
Anywhere Chrome runs
Windows, macOS, Linux, and ChromeOS — there are no native components to install.
Store-policy clean
Plain JavaScript, requested permissions kept to the minimum, and full compliance with Chrome Web Store review rules.
FAQ
Frequently asked questions
Short answers about installing, using, and trusting bilibili Video Downloader.
Yes. Every feature is free, with no account, no ads, and no
artificially crippled "pro" tier. If you like it, telling a
friend is the best payment.
bilibili Video Downloader ships as a Chrome extension and works
in any Chromium-based browser, including Edge, Brave, Opera, and
Vivaldi.
Progressive MP4 and WebM files are saved as-is. HLS playlists
and MPEG-TS streams are stitched into one file. On BiliBili.tv,
DASH video and audio tracks are downloaded and merged into a
single MP4 in the quality you picked.
No — by design, it covers sites other than YouTube. For
BiliBili.tv, Facebook, Instagram, and thousands of sites that
serve direct video, it lists everything it can detect.
None. bilibili Video Downloader has no backend server, no
analytics, and no crash reporting. Downloads, history, and
settings live only in your browser's local storage. This
marketing site also sets no tracking cookies — it stores just
your theme preference.
No. Merging of video and audio tracks is built into the
extension in plain JavaScript. There is nothing to install,
configure, or keep updated.
Some sites use DRM-protected playback, which the extension
deliberately does not touch, and YouTube is out of scope by
design. On other sites the video often only appears after you
press play — start playback and check the popup again.
It depends entirely on what you download and where you live.
Saving your own uploads, openly licensed content, or material
you have permission to keep is generally fine; saving copyrighted
media without permission is not. You are responsible for using
the tool lawfully and respecting each site's terms.
In your browser's regular downloads folder. Every history entry
can open the file, and Settings has an Open download folder
button.
Yes — it's a Chrome extension, so it works on Windows, macOS,
Linux, and ChromeOS wherever Chrome or a Chromium browser runs.
There are no native components.
Install once, forget it's there
bilibili Video Downloader sits quietly until a page has a video you want — then it's one click to a clean, local file.
