Bilibili Video Downloader

Paste a Bilibili link into the box above, tap Download, and this Bilibili video downloader pulls the clip straight from Bilibili's own delivery servers, then tap Save to store one MP4 file with the video and its audio already combined. No Bilibili account, browser extension, or desktop client needed.

Bilibili runs on genuinely different mechanics than most platforms covered on this site. Video and audio arrive as two separate files behind the scenes, a signature bullet-comment layer floats over every player, and how much resolution you can actually reach depends on whether you're logged in at all. The sections below cover what that means in practice for a link pasted here, including the honest limits.

Why Some Downloaded Bilibili Videos Have No Sound

If you've ever grabbed a Bilibili video with a generic browser extension and ended up with a file that plays picture but no sound, there's a specific technical reason for it. Bilibili streams most videos using DASH (Dynamic Adaptive Streaming over HTTP), which sends video and audio as two independent files rather than one combined stream.

Both tracks arrive as fragmented .m4s files: one carries only the picture, the other only the sound. A basic tool that just grabs "the video URL" off the page often captures the video-only stream and stops there, which is exactly how a downloaded clip ends up silent.

This Bilibili video downloader is built specifically to handle that split. It requests both the video and audio streams for a given link and returns one MP4 with the two already combined, so the Save button on this page produces a normal file with sound, not a muted one.

What Happens to Danmaku Comments in a Downloaded Video

Danmaku (literally "bullet comments") is Bilibili's defining feature: viewer comments fly across the screen in real time, timed to the moment in the video they were posted about. It's central to how people actually watch Bilibili, but it's not something most people want baked into a saved file.

The good news is that Danmaku was never part of the video file to begin with. Bilibili's player loads the video stream and the comment data as two completely separate requests: the comments come from a dedicated endpoint keyed to the video's internal ID, delivered as a timed text feed, and it's the browser or app itself that draws them on top of the video as it plays.

Because Danmaku is rendered client-side rather than burned into the source file, a video fetched directly from Bilibili's delivery servers (which is what happens when you paste a link here) never had comments in it to remove. The file this tool returns is clean by default, not specially filtered.

The Real Resolution Ceiling for a Bilibili Video Downloader Without Login

Bilibili ties video quality directly to account status, more aggressively than most platforms. It's worth being upfront about this rather than glossing over it, because it directly affects what a link-based tool like this one can deliver.

Anonymous, logged-out requests (which is what this tool sends, since it never asks for your Bilibili username or password) generally receive Bilibili's lowest public tier, commonly somewhere in the 360p to 480p range depending on the specific video. Logging into a free Bilibili account unlocks 720p and standard 1080p. The highest tiers (1080P60, 4K, HDR, and Dolby Vision) sit behind a paid "Big Member" (VIP) subscription on top of that login.

That means a tool that doesn't handle your Bilibili login, this one included, is realistically working from the same tier any logged-out visitor gets, not from whatever the uploader's original file quality was. That's a genuine trade-off, not a minor detail: treat any downloader that claims it always reaches "maximum resolution" without ever asking for your account with some suspicion.

Reading Bilibili's Link Formats: BV IDs, b23.tv, and Old AV Numbers

A link copied from Bilibili can look different depending on where it came from, and all of the common shapes work here.

The standard desktop format is a full address like bilibili.com/video/BV1xx411c7mD: the BV code is Bilibili's current video ID system, introduced in March 2020 to replace the older, purely numeric scheme. Every video uploaded since then gets a BV ID, and most older videos have one too, even if they were originally published under the previous format.

Sharing from the mobile app usually produces a much shorter b23.tv link instead: Bilibili's own official link-shortener, used so share text fits neatly into chat apps and social posts. A b23.tv link is just a redirect; pasting one here resolves it to the underlying video the same way opening it in a browser would.

Occasionally you'll still run into an old link built around an AV number instead of a BV code: a leftover from Bilibili's original ID system, before the 2020 switch. Both current BV-format links and legacy av-number links resolve correctly, so an older bookmark someone shares doesn't need to be converted by hand first.

Multi-Part Uploads and the ?p= Page Number

Plenty of Bilibili uploads aren't a single video at all: tutorials, full anime seasons, and long-form series are frequently posted as one listing split into numbered parts, each playable from the same page.

Bilibili tracks which part you're watching with a ?p= number at the end of the URL, starting at ?p=1 for the first part. A link like bilibili.com/video/BV1xx411c7mD?p=3 points at part three specifically, not the series as a whole.

Paste a link that already includes a ?p= number and this tool fetches that exact part. Paste the base link with no ?p= at all and it defaults to part one, the same behavior you'd get opening the link in a browser.

This Tool vs. Bilibili's Own Offline Cache

Bilibili's own app has a built-in offline option, so it's fair to ask why a separate downloader is useful at all. The short answer is what you get to do with the file afterward.

The app's offline cache is meant strictly for watching inside Bilibili itself while offline: it's not a normal video file sitting in your phone's storage. It won't show up in your Photos app, won't open in VLC, and won't attach to an email or a chat message, because it isn't stored in a standard, portable format.

That trade-off is really the whole reason a Bilibili video downloader exists as a category of tool at all: Bilibili's own cache was never designed to hand you a portable file.

What This Bilibili Downloader Can't Reach

Most public Bilibili videos work exactly as described above. A few categories genuinely don't, and it's worth knowing which before pasting a link:

Why an Active Livestream Won't Download Yet

Bilibili's live-streaming side (game streams, VTuber broadcasts, music sets) runs on continuously-appended video chunks rather than a single finished file. There's no complete video sitting at a fixed address until the broadcaster actually stops streaming.

That's a structural fact about how live video works everywhere, not a Bilibili-specific restriction: the same is true trying to download an in-progress stream on most other platforms. Once the broadcast ends, though, many streamers publish an official VOD replay to their channel as a normal post, and that downloads the same way as anything else on this page.

Saving Bilibili Videos on iPhone, Android & Desktop

The steps are the same everywhere (copy a link, paste it above, tap Download, then Save), but where the finished MP4 ends up depends on the device.

On iPhone

1. Copy the link: in the Bilibili app or on bilibili.com in Safari, tap Share and copy the video link.
2. Paste it: open this page in Safari, paste the link, and tap Download.
3. Save it: tap Save on the result. Safari places it in the Files app under Downloads; open it there, tap Share, then choose Apple's own Save Video action to move a copy into Photos.

On Android

1. Copy the link: tap Share on the video and copy the link, from either the Bilibili app or Chrome.
2. Paste it: open this page, paste the link, and tap Download.
3. Save it: tap Save. The MP4 lands directly in the phone's Download folder and is usually visible in Gallery within moments.

On Desktop

1. Copy the link: on bilibili.com, copy the address straight from the browser's address bar, or use the page's own share/copy-link option.
2. Paste it: paste the link into the box on this page and click Download.
3. Save it: click Save. Long anime episodes and multi-part uploads can run several hundred megabytes, so confirm there's enough free space before saving a full season.

Fixing a Bilibili Link That Won't Download

A handful of causes account for nearly every failed Bilibili download:

• A truncated b23.tv link: re-copy the short link from Bilibili rather than typing or editing it by hand.
• An expired stream token: Bilibili's underlying media URLs carry short-lived access tokens; if a link worked yesterday and fails today, reload the original video page and paste a fresh copy of the link.
• A paid or region-locked Bangumi title: confirm the video plays for you directly on Bilibili first: if Bilibili itself asks for a Big Member subscription or blocks the region, no downloader can get around that.
• A members-only or private post: content limited to a creator's paying members returns an error rather than a video, by design.
• A link still mid-livestream: wait for the broadcast to end and the VOD replay to post.

Copyright, Fair Use & Reused Audio

Downloading a public Bilibili video for personal, offline viewing is standard fair-use territory in most places, the same as it would be for any other platform. What you do with it afterward is where the actual legal line sits.

Reposting someone else's Bilibili upload as your own, or using it commercially, needs the original creator's permission: that applies whether the clip is a vlog, a gaming highlight, or a fan-edited anime compilation.
