Save Bilibili (哔哩哔哩) videos as plain MP4s — up to 4K and 8K where the source provides it, with the real audio muxed into one clean file. High-resolution and members-only videos are reachable when you sign in with your own Bilibili account, kept on your device. Danmaku are left off; you get the plain video.

Yes. The current release is a free public build — paste a link and save, with no account and no sign-up.
Whatever the video offers, up to 4K and 8K. Higher resolutions on Bilibili usually require being signed in — use your own login and it stays on your device.
No — DLKeep saves the plain video and audio as one MP4, without the scrolling danmaku overlay.
You are responsible for having the right to download a given video. DLKeep is a tool — only save content you own, that is yours to keep offline, or that the rights-holder permits. See our Terms.
Standard video pages (bilibili.com/video/BV…) including multi-part collections. Paste the address of the specific part you want; DLKeep resolves that part rather than the whole collection.
Bilibili's CDN checks where the request comes from, so the direct video address only works with the right referring page attached. DLKeep keeps that context for the whole download — which is also why copying the resolved link into another downloader fails.
No. At higher resolutions Bilibili sends video and audio separately; DLKeep fetches both and muxes them into one MP4 without re-encoding, so quality is exactly what the source had.
Paste the specific part you want — DLKeep saves that one. For a series, queue the parts you need one at a time.
