How it works
Open the public Niconico post and copy its share link. A direct link looks like https://www.nicovideo.jp/watch/sm9. A profile or search page will not work.
Paste the link into PasteGrab. Pick Best quality, MP4, MP3, 720p, or Smallest file before you preview it.
Select Preview formats to confirm the title, length, and available files. If the page is private or unavailable, you will see an error before starting a download.
Start the job and follow its progress. When the file is ready, use the download link to save it to your device.
Benefits
PasteGrab gets the file from a public Niconico page. You do not need to upload a copy first.
Pick video, audio, the best available quality, or a smaller file before you start.
Copy a Niconico share link on your phone or computer and open PasteGrab in your browser.
The job page shows what is happening and gives you a link when the file is ready.
Features
Check the title, length, and available formats before you download.
Choose MP4 for video or MP3 when you only need the sound.
Use the Paste button when your browser allows clipboard access, or type the link into the field.
If a link is unavailable, the preview tells you before you wait for a file.
Output
PasteGrab exposes format presets before preview and may reveal additional streams afterward depending on what Niconico publishes for that URL. Video pages typically offer MP4 output; audio-heavy Niconico posts may map cleanly to MP3.
If you need the smallest possible file for messaging apps or email attachments, choose Smallest file. For archival or re-editing, start with Best quality and only downshift if storage or bandwidth requires it.
| Format | Best for |
|---|---|
| Best quality | Merges the best video and audio streams available on the Niconico page into a single file. |
| MP4 | Standard H.264-style output suitable for playback, slides, and most editors. |
| MP3 | Audio-only export when the Niconico post is music, speech, or background audio you do not need visually. |
| 720p | Caps video height for faster downloads and smaller storage on long Niconico clips. |
| Smallest file | Prioritizes compact output when quality is less important than speed. |
Devices
Use PasteGrab in a modern browser on your phone, tablet, or computer. Copy the Niconico share link, paste it into the downloader, and save the finished file.
Your browser may ask for clipboard permission when you use the Paste button. You can always paste directly into the field instead.
Use Chrome, Edge, Firefox, or Safari to preview and download.
Copy the Niconico share link, then open PasteGrab in Safari or Chrome.
The same steps work with touch controls on a tablet.
Support
Confirm you pasted a direct Niconico media URL (https://www.nicovideo.jp/watch/sm9), not a profile or search page. Standard Niconico watch URLs.
Niconico pages that require login or regional access cannot be fetched by PasteGrab. Only public URLs you can open in an incognito window will resolve.
Long Niconico files take time. Keep the job tab open. If progress stalls beyond ten minutes, copy the link again and retry — transient Niconico CDN issues sometimes clear on a second attempt.
Preview again with a different preset selected before clicking Start download. Format locks in at job creation time.
Tap inside the URL field first, then tap Paste. Some browsers block clipboard access until user interaction occurs.
