Save Audio From Nicovideo

Paste the Nicovideo link. Pick the audio file. Done.

How the Nicovideo link becomes the Audio file

No app, no extension, no account. The whole thing is a text box and a link — you paste the Nicovideo URL, we resolve it, you get the audio file. Anything more than that would be us adding steps for our benefit rather than yours. The extractor covers 3 separate Nicovideo URL shapes, so a link copied from anywhere on the site usually resolves as-is. Nothing here re-encodes, so an audio-only file exists only where Nicovideo publishes one; where it ships audio muxed inside the video stream, that stream is what there is to take. Nicovideo is handled by the media route, which reads the site's own rendition list before choosing anything.

Two ways in: the box above, or prefix the Nicovideo 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 Nicovideo 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 Nicovideo 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 Nicovideo 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 Nicovideo 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 Nicovideo 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 Nicovideo did not publish.

Among others: search, search:date, search_url. 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. 3 different Nicovideo 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 Nicovideo address it will almost certainly resolve.

You get the best progressive rendition Nicovideo publishes for that item, chosen automatically. There is no upscaling on offer, because inventing pixels that Nicovideo never encoded would make the file bigger and not better.

No. This is a web page with a text box. Anything that asks you to install an executable to save the Nicovideo link is asking for more access than the job requires.

Yes, identically. The work happens on our side, so an old phone on a slow connection is no worse at resolving the Nicovideo link than a desktop — it just downloads the file more slowly afterwards.

No cap you have to pay to lift and no trial that expires. The paid plan exists for people who download in bulk or want the API; a single Nicovideo link does not need it and never will.

Audio telechaje herit bitrate soti nan Nicovideo upload (tipikman 128-320 kbps). Pa re-encoding, pa kalite pèt kont sous la.

Telechaje son pa gen filigran vizyèl. MP3 se son Nicovideo uploader a voye; Tikt.com pa enjekte ID3 tags ni son cues.

Nicovideo sèvi ak Audio resous kòm yon URL piblik. Tikt.com fèmen li san yo pa janm enskri nan kont ou.

Ka a tipik: soundtrack extraction. Audio sou Nicovideo se chwa dwa lè ou vle egzakteman ke moso medya san yo pa glisman nan rès la nan pòs la.

Tikt.com bay ou yon kopi lokal yon resous ki disponib pou piblik la; re-itilizasyon komèsyal mande pèmisyon detèmine dwa.

Pa gen enskripsyon. Pa gen kont. Pa gen kòd ki lonje sou idantite Nicovideo ou. Tikt.com pa anrejistre ki Audio URL ou kole.

Telechaje ou yo pa estoke oswa swiv. Fichye yo ap trete imedyatman epi yo voye dirèkteman ba ou.
