The Best Bilibili Downloaders, Compared
“Which Bilibili downloader should I actually use?” It’s a fair question — and a hard one to answer honestly, because nearly every “best Bilibili downloader” article on the internet is an affiliate list dressed up as a review. We built this page differently: instead of ranking tools with invented scores, we published our criteria, explained how we evaluate, and compared the three main approaches — web tools, desktop software, and browser extensions — on facts anyone can verify.
How we evaluate: criteria you can re-test yourself
A good Bilibili downloader should be judged on things that are publicly verifiable, not on how generously its marketing copy scores itself. Here are the criteria we use — and you can test every one of them in about five minutes without creating an account anywhere:
- Merged audio by default? Bilibili serves video and audio as separate streams (DASH). Many tools hand you a silent MP4 because they skip the merge step. A trustworthy tool merges audio into the file automatically.
- Are quality options honest about gates? Some quality levels (1080p, 4K, high bitrate audio) require a Bilibili account, premium membership, or specific login states. An honest tool says so instead of silently delivering 480p.
- No signup required? Requiring an account just to download is a red flag — it usually exists to harvest emails or gate features.
- Subtitle support? Bilibili hosts CC subtitles and some fan translations. The better tools offer them as SRT downloads alongside the video.
- BV, AV, and b23.tv link support? Bilibili uses three URL formats — the modern
bilibili.com/video/BV…, the legacyav…ID, and the shortenedb23.tvshare link. A complete tool parses all three. - Honest limits stated? Every tool has limits: file-size caps, rate limits, formats it can’t produce. Honest tools state them upfront instead of failing silently.
- No password asked? This is non-negotiable. A downloader never needs your Bilibili password (or anyone’s). Tools that ask for login credentials are harvesting them. See our full guide to whether Bilibili downloaders are safe.
Methodology and review date
We do not operate a test lab, and we won’t pretend we do. Our evaluation compares approaches (web-based tools, desktop software, browser extensions) on architectural facts — what’s installed, what’s required of you, and what’s publicly documented about how each class of tool works. We do not assign numeric scores or ratings, because a score of “9.4/10” from someone who never installed the software is fiction, not data.
Last reviewed: October 2026. Re-reviewed quarterly. If a tool changes its features, our description of it changes too — not its score.
Comparison: web tools vs desktop software vs browser extensions
The table below compares approaches, based on publicly documented features, October 2026 — re-tested quarterly. Where specific tools are named, we describe only what their projects or docs publicly state.
| Criterion | Web tools (e.g. SaveBili) | Desktop software (e.g. yt-dlp, BBDown) | Browser extensions |
|---|---|---|---|
| Merged audio by default | Yes on quality tools — handled server-side, you get one finished MP4 | Yes — tools like yt-dlp merge with ffmpeg automatically; BBDown merges DASH streams natively |
Mixed — many capture streams but deliver video-only files |
| Quality options honest about gates | Varies — SaveBili states which qualities are available without login | Generally yes — these tools document exactly what each login state unlocks | Often unclear — options may appear selectable but deliver lower quality |
| Signup required | No — paste link, download | No accounts on the tool itself (though a Bilibili login cookie may be needed for premium quality) | Some require extension-store accounts or signups for full features |
| Subtitle support | SaveBili offers subtitle (SRT) download where available | Yes — yt-dlp and BBDown document subtitle extraction | Rarely supported |
| BV / AV / b23.tv support | Yes on SaveBili — all three parsed, including our link inspector that shows what a link resolves to | Yes — documented URL support covers all formats | Usually only the page you’re currently viewing |
| Honest limits stated | Good web tools state caps; verify before trusting | Documented in open-source repos — the most transparent category | Least transparent — reviews often mention undisclosed limits |
| Password asked | Never on legitimate tools — never enter credentials | Never as a password prompt; some accept your own browser cookie for premium quality (your choice, your machine) | Exercise caution — extensions run with broad permissions |
| Install required | No install — works in the browser | Yes — install + (for yt-dlp) command-line comfort | Extension install from the browser store |
| Batch downloads / automation | Not typical — designed for one video at a time | Best in class — playlists, batch scripts, scheduling | Manual, one-by-one |
| Format control | Curated options (MP4 / MP3 / subtitles) | Full control — codecs, containers, bitrates | Limited to what the extension captures |
Who should use what
There’s no single “best” — there’s a best for you. Here’s our honest guidance:
- Comfortable with the command line and want automation, batch downloads, or playlists? Use yt-dlp (open source, actively maintained). It wins on power, format control, and transparency — you trade convenience for control. BBDown is a solid Bilibili-focused alternative.
- Want a video now, with zero install and zero learning curve? Use a web tool like SaveBili: paste the link, pick quality, download the merged MP4. You trade batch power for instant results — no setup, no terminal.
- Live inside your browser and download occasionally? A reputable extension can work, but check its permissions and reviews carefully — and verify the audio merge with our no-sound troubleshooting guide if you get a silent file.
- Chasing the highest available quality? Read our Bilibili video quality guide first — some resolutions are gated behind login or membership no matter which tool you use.
If you’re not sure where your link points, run it through our Bilibili link inspector — it shows exactly what video a BV, AV, or b23.tv link resolves to before you download anything.
Try it the easy way: SaveBili — paste a Bilibili link and download in seconds, no signup, no install.
Why most “top 10” Bilibili downloader lists mislead
Nearly every “top 10 best Bilibili downloaders” article follows the same template: ten tools, invented scores, “9.8/10 — best choice!” And nearly every one is monetized through affiliate links, paid placements, or ads from the very tools being “reviewed.” That’s why they all recommend different winners, none publish testable criteria, and the scores never change when a tool breaks.
We take no affiliate commissions from any downloader mentioned here, and we publish our criteria instead of our scores. If this page ever recommends SaveBili for a use case, it’s because the criterion points there — and the table above shows exactly where it doesn’t.

Frequently asked questions
What is the best Bilibili downloader in 2026?
It depends on what you need. For zero-install convenience, a web tool like SaveBili is fastest. For power users who want batch downloads and format control, the open-source command-line tool yt-dlp is the most capable. There’s no honest single winner — any list that names one without explaining the tradeoffs is selling you something.
Is it safe to use a Bilibili downloader?
Legitimate tools that only need a video URL are generally safe. Never use a tool that asks for your Bilibili password, payment details, or a software install from an unverified source. Our safety guide walks through the red flags in detail.
Why do some Bilibili downloads have no sound?
Bilibili serves video and audio as separate streams. Tools that don’t merge them produce a silent MP4. This is the single most common downloader problem — our no-sound guide explains the fix for every approach.
Can I download Bilibili videos in 4K?
Some videos and some tools support it, but high resolutions are often gated behind account or membership status, and availability varies by tool. See our quality guide for what’s realistically achievable.
Do Bilibili downloaders support b23.tv short links?
Complete ones do. SaveBili parses BV, AV, and b23.tv links; desktop tools like yt-dlp and BBDown handle all three as well. Some extensions only work on the page you have open.
Do I need to create an account to download?
No — for publicly available videos, no legitimate downloader needs you to sign up or log in. If a tool demands registration before it will download a public video, treat that as a warning sign.
A quick reminder: only download videos you own, created yourself, or have permission to save — your own uploads, Creative Commons content, or videos whose creators allow downloading. Respect copyright and Bilibili’s terms of service.
