Niconico Video Downloader — MP4 Out

Niconico serves MP4 and that is the container you keep.

Finished Niconico uploads versus live output

Part of Niconico is region-locked, which is the usual explanation when a link opens for one person and 404s for another. The extractor targets the regions the platform serves (JP) where it can. Anything that does resolve comes back as an ordinary video file. Niconico is one of the broader integrations here — 6 distinct link shapes are handled rather than a single canonical one. Niconico supports signed-in sessions upstream, which is precisely how it hides private material; we browse anonymously, so that material stays hidden. Niconico 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 Niconico URL you are already looking at with tikt.com/:

tikt.com/https://www.example.com/path/to/media
How to get the Video file
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.

Technical FAQ — Tikt.com Niconico Media Converter

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.

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.

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.

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.

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.

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.

MP4 — whatever Niconico itself serves. The container is passed straight through rather than rebuilt, so there is no second round of compression between the platform's copy and yours.

The Video downloader for Niconico fetches the video stream the platform delivered and writes it as MP4 (H.264 + AAC).

Video downloads from Niconico top out at 1080p when the platform served that variant. Lower-resolution fallbacks exist if your IP gets a region-restricted stream.

MP4 (H.264 + AAC) plays in QuickTime, VLC, Windows Media Player, every modern browser, iOS / Android natively. No codec packs required.

Video rights stay with whoever uploaded the clip to Niconico. Tikt.com gives you a local copy; archival and personal-editing are typically fine, commercial reuse depends on the original licence.

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

Free. The Video downloader for Niconico is unmetered for personal use -- no per-file fee, no daily cap.
