Your Questions Answered: Saving Niconico Videos, Photos & Audio with Instag

Paste any Niconico URL into the box above and press Download. Instag does not require you to sign in to Niconico — public links work out of the box.

On the Niconico videos endpoint Instag returns MP4 with H.264 video and AAC audio — the most compatible format. It plays on every phone, browser, smart TV, and console out of the box.

Niconico videos typically caps at 1080p Full-HD. Instag pulls the same resolution the platform actually serves in its own player.

Niconico serves content as HLS streaming segments. Instag stitches the segments back into a single MP4 on the server side, so you get one clean file instead of a folder of .ts chunks.

Most Niconico downloads are people saving content for personal offline viewing. Instag does not charge per download, does not require an account, and does not log what you saved.

Niconico is a dedicated video platform — clips can be hours long and uploads are versioned. Instag fetches the latest version of whichever URL you paste.

There's no daily cap on Niconico videos downloads. Paste each URL on its own line for a batch; failed URLs are skipped individually rather than aborting the whole batch.

Yes — Niconico videos downloads from Instag are MP4 (H.264 + AAC). That format plays on every iPhone, Android phone, smart TV, and console without re-encoding.

Niconico videos downloads through Instag are free regardless of clip length or resolution. Pro removes ads and adds batch downloads.

Saving Niconico content for personal use is generally fine; redistributing copyrighted material without permission is not. Instag does not own or license Niconico content — you are responsible for how you use what you download.

Instag does not retain Niconico videos URLs, downloaded MP4s, or any account info. videos downloads stream through and are discarded — there is no per-user history.

Retry once — large Niconico videos occasionally hit transient CDN errors. If it still fails, the source may be geo-restricted, age-gated, or marked subscribers-only by the uploader (Instag doesn't bypass any of those).
