How Do You Download MP4 From Nicovideo?

The short version

The Nicovideo link is resolved by our media extractor. It asks Nicovideo for the list of renditions it publishes for that item, takes the best progressive one and streams it through to you as the MP4 file. Nothing is transcoded on the way, so quality is whatever Nicovideo encoded at. The extractor covers 3 separate Nicovideo URL shapes, so a link copied from anywhere on the site usually resolves as-is. No credentials are involved anywhere in this path — neither yours nor ours.

Either paste a Nicovideo link above, or put tikt.com/ in front of any Nicovideo URL in your address bar:

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.

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.

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. 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.

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.

No. The file streams through and is gone; there is no library, no history and nothing to delete afterwards. That is also why we cannot re-send you something you downloaded last week.
