About Bilibili Downloader

Bilibili Downloader lets you grab anime episodes directly from Bilibili, including bangumi with season and episode numbering. Choose your resolution from 360p up to 4K, depending on availability and your account tier. The extension automatically merges multi-part videos so you get complete episodes in one file.

What sets this apart is the ability to export danmaku scrolling comments as ASS or SRT subtitle files. When you play the MP4 video in VLC or MPV, the comments roll across the screen just like they do on Bilibili. It’s the full experience without needing an internet connection.

Batch download an entire series or collection with a single click. The tool queues episodes, tracks progress, and retries automatically if something fails. You can even choose between MP4 and MKV output to suit your playback setup.

Short, practical feedback from people using Bilibili Downloader in real workflows.

Handles Bilibili's multi-part system cleanly

Finally a downloader that actually handles Bilibili's multi-part video system. I archive educational content from Chinese creators and this saves me hours of manual work. The danmaku export is a bonus I didn't expect.

Good for offline anime watching from Bilibili

I use this to download anime episodes from Bilibili for offline viewing during my commute. The quality matches what I see in the browser and the episode naming is automatic. Very reliable.

Best tool for Bilibili DASH stream merging

The DASH stream handling is what sold me. Other tools couldn't merge Bilibili's separate audio and video streams properly, but this one does it automatically for the streams I saved. Clean MP4 output.
