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.

Technical FAQ — Tikt.com Nicovideo Media Converter

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 downloads inherit the bitrate from the Nicovideo upload (typically 128-320 kbps). No re-encoding, no quality loss vs the source.

Audio downloads don't carry visual watermarks. The MP3 stream is the audio the Nicovideo uploader pushed; Tikt.com doesn't inject ID3 tags or audio cues.

Nicovideo serves the Audio asset as a public URL. Tikt.com fetches it without ever signing in to your account.

The typical case: soundtrack extraction. Audio on Nicovideo is the right pick when you want exactly that media slice without dragging in the rest of the post.

Audio rights belong to whoever Nicovideo licensed the track from. Tikt.com hands you a local copy of a publicly-streamable asset; commercial reuse requires the rightsholder's permission.

No signup. No account. No cookies tied to your Nicovideo identity. Tikt.com doesn't log which Audio URL you pasted.
