Niconico Audio and Replay Downloader

The extractor reads Niconico's own rendition list and takes the best progressive one.

Finished Niconico uploads versus live output

Niconico publishes live output next to finished uploads, and the two behave differently. A replay, VOD or clip has a settled file behind it and downloads normally. A stream that is still running does not have an end yet, so wait for the replay to appear before pasting the link. Niconico is one of the broader integrations here — 6 distinct link shapes are handled rather than a single canonical one. Nothing here re-encodes, so an audio-only file exists only where Niconico publishes one; where it ships audio muxed inside the video stream, that stream is what there is to take. Niconico supports signed-in sessions upstream, which is precisely how it hides private material; we browse anonymously, so that material stays hidden.

Two ways in: the box above, or prefix the Niconico URL you are already looking at with tikt.com/:

tikt.com/https://www.example.com/path/to/media
What you actually have to do
1. Copy the Niconico link

Use the address bar or the platform's own share button — both give a URL the extractor recognises. Point it at the single item you want, not the page around it.

2. Let it read the renditions

Paste the URL above. The extractor asks Niconico which renditions exist for that item and picks the best progressive one rather than assuming a quality.

3. Save what comes back

The file arrives in the container Niconico served it in, and the extractor does not rebuild it — so what you end up with is what the uploader encoded, for better or worse.

Kesyon komen

Only where Niconico publishes an audio rendition of its own. The extractor takes what the site serves and re-encodes nothing, so on a platform that ships audio muxed inside the video stream there is no separate audio file to hand you — you get the stream that carries it. That is a limit of not transcoding, and not transcoding is also why nothing loses quality here.

It reads the rendition list Niconico publishes for that item and takes the highest progressive one — a single file with video and audio already muxed, so nothing has to be recombined afterwards. It never re-encodes, so it cannot give you a quality Niconico did not publish.

No, and that is deliberate. Niconico gates private material behind a signed-in session; we fetch as an anonymous browser and hold no credentials, so we see exactly what a logged-out visitor sees. If a post needs a follow request to view, it needs one to download.

Not usefully. A running stream has no end yet, so there is no finished file to hand you. Wait until Niconico publishes the replay or VOD — at that point it behaves like any other item and downloads normally.

Region locking. Parts of Niconico are only served in certain territories (JP), and the platform decides that per request. The extractor targets those regions where it can, but a hard geo-block on the platform's side is the platform's decision, not something we can talk it out of.

Among others: history, live, playlist, series. Those are separate URL shapes with separate handling behind them, which is why a link that looks nothing like the last one you pasted still works.

No. 6 different Niconico URL shapes are recognised, which covers the ordinary address-bar URL, the share variant and most of the odd ones in between. Paste whatever you copied; if it is the Niconico address it will almost certainly resolve.

Whatever the URL names. A single-item Niconico link returns that item; a collection or feed URL returns what the collection holds. If you got more than you expected, you pasted the container rather than the item.
