Niconico downloader — FAQ
Is the Niconico downloader free?
Yes. The current release is a free public build — paste a link and save, with no account and no sign-up.
Do I need to log in to download from Niconico?
Many videos work without it; videos that only play while signed in are reachable with your own Niconico login, which stays on your device.
Does the download include the scrolling comments?
No — DLKeep saves the plain video and audio as one MP4, without the comment overlay.
Is it legal to download Niconico videos?
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.
Which Niconico videos need a login?
Public videos work with no account at all. Members-only and age-restricted uploads need your own Niconico login, which stays on your device — DLKeep uses the guest path first and only asks when the video actually requires it.
What quality does Niconico save at?
Niconico serves video and audio as separate adaptive streams; DLKeep picks the best of each and muxes them into one MP4, so you get the full quality the upload has rather than a lower single-file version.
Does the download include the danmaku comments?
No — you get the plain video and audio as one MP4, without the scrolling comment overlay that plays on the site.
Why do video and audio arrive separately?
Niconico's current delivery publishes them as separate adaptive streams. DLKeep picks the best of each and muxes them into a single file, so you never deal with two files.
