Bilibili is packed with high-quality content — anime, tech reviews, documentaries — and much of it is available in 4K Ultra HD. The catch: Bilibili offers no direct download button for most videos. Here is how to save any Bilibili video in full 4K quality, free and without a watermark.
What you will need
- The link to the Bilibili video (or its BV number).
- A browser — Chrome, Safari, Edge or Firefox all work.
- About 30 seconds.
Step-by-step
- Open the Bilibili video and copy its URL from the address bar. On mobile, tap Share then Copy Link.
- Go to bbvideosaver.com and paste the link into the download box.
- Click the download button and wait a few seconds while the video is processed.
- Choose 4K MP4 (2160p) from the quality list — pick a lower resolution for a smaller file.
- The file saves straight to your device. No sign-up, no watermark.
Tips for the best quality
Not every upload is truly 4K — if the uploader posted in 1080p, that is the maximum available. The tool always offers the highest quality the source has.
4K files are large, often 1 to 2 GB per hour, so check you have enough storage, especially on phones.
For audio-only content like podcasts or music, choose MP3 instead to save space.
Is it free?
Yes — downloading in 4K is completely free, with no account required and no watermark added.
