How to download a video from Niconico
- 01
Copy the video link
On nicovideo.jp, open the video and copy its address, which looks like nicovideo.jp/watch/sm12345. Short nico.ms links, which you often get when a video is shared, work too.
- 02
Paste it above
Put the link in the box and tap Download. SaveArrow checks the video and shows the MP4 and MP3 options for it.
- 03
Save it, keep the page open
Pick MP4 or MP3. The file is assembled while it downloads, so it can’t be resumed if interrupted: leave this page open until it finishes.
What you can save from Niconico
The quality every viewer gets
SaveArrow saves the quality Niconico offers to everyone for the video, often 360p. Higher qualities reserved for Niconico Premium aren’t available, so the file matches what a viewer without Premium sees.
Sound as MP3
Keep the audio of a game commentary, a talk or a cover as an MP3, converted while the file downloads. Handy for listening on the go without the picture.
No comment overlay
The comments that scroll across Niconico videos aren’t part of the file. You get just the picture and the sound, which play in any player on iPhone, Android or a computer.
sm and nico.ms links
Paste a nicovideo.jp/watch/sm… address or a nico.ms short link; both lead to the same video. SaveArrow works in Safari, Chrome and other browsers, free and with no account.
