Bilibili has grown into one of the largest video communities in Asia, and plenty of viewers outside China watch it too — for anime, gaming clips, music performances, and commentary you simply won't find anywhere else. The catch is that Bilibili doesn't offer an official "save for offline" button on the web, so if you want a video available without an internet connection, you need a dedicated downloader. This guide walks through the whole process end to end.

Why people download Bilibili videos

The most common reason is simply patchy connectivity — mobile data on a commute, airplane wifi, or a slow connection abroad all make streaming unreliable. Beyond that, some viewers want a personal backup of a video before it's taken down or region-locked, or want to watch content in an app that doesn't support in-browser Bilibili playback. Whatever the reason, the process below is the same.

Step-by-step: how to download a Bilibili video

Step 1 — Copy the video link Open the video on the Bilibili app or bilibili.com, tap the share icon, and choose Copy Link. You can also just copy the URL straight out of your browser's address bar — either a full bilibili.com/video/... link or a shortened b23.tv link works.

Step 2 — Paste it into the downloader Come back to this page, tap the input box at the top, and paste the link. If you copied it just a moment ago, the Paste button will grab it automatically.

Step 3 — Fetch the video details Tap Download Video (MP4). The tool reads the video's title, cover image, and an available stream URL directly from Bilibili's own public endpoints — the same data your browser already loads to play the video normally.

Step 4 — Save the MP4 file Once the preview card appears, tap Save MP4 File. Your browser will download the file to your usual downloads folder or camera roll, ready to watch offline.

Getting the best possible quality

Bilibili adjusts the resolution it serves based on whether you're logged in and what plan your account has. Without a logged-in session, most public streams top out in the 480p–720p range, which is what a simple link-paste downloader can retrieve. If a video looks softer than expected:

  • Try the original, non-shortened bilibili.com/video/ link rather than a b23.tv redirect — it occasionally preserves slightly better metadata.
  • Confirm the source video itself was uploaded in HD. A downloader can't add detail that was never in the original upload.
  • For long videos, remember file size scales with both resolution and length — a 20-minute 1080p video can easily be several times larger than the same clip at 480p.

Desktop vs. mobile: does it matter?

Not really. Because everything runs through the browser, the same paste-and-download flow works identically on a laptop, an Android phone, or an iPhone — there's nothing to install either way. The only practical difference is where the finished file lands: desktop browsers typically save to a Downloads folder, while phones usually save straight into your gallery or a Files app.

Common errors and how to fix them

"Failed to fetch video details." This almost always means the link was copied incorrectly, the video is private or region-restricted, or it's been removed. Double check the link opens normally in a separate tab first.

The download starts but the file won't play. This usually points to an interrupted download rather than a bad video — try again on a stable connection, and avoid switching apps mid-download on mobile.

Video plays but has no sound, or vice versa. Some higher-quality Bilibili streams split video and audio into separate tracks (a delivery method called DASH). A downloader built around simple progressive links will sometimes need to fall back to a lower quality tier that keeps both tracks together in one file.

A quick word on doing this responsibly

Downloading a personal copy for offline viewing is very different from re-uploading someone else's video elsewhere. Stick to content you have the rights to, or that you're using for personal, non-commercial viewing, and never redistribute a saved file as your own work. See our full downloading responsibly guide for more detail.
