NoBsDL Video Downloader (userscript)
Download videos as MP4 and audio as MP3 without leaving the page.
Open the panel, pick a real quality with its file size, watch the live server
progress, and the file goes straight to your browser's downloads. Powered by
NoBsDL.
Install
- Install Tampermonkey or
Violentmonkey.
- Install the userscript from
Greasy Fork (updates arrive
automatically) or a mirror:
What you get
- In-page downloads: a small NoBsDL button sits in the corner of supported
media pages. Choose a format and the file is saved without opening a new tab.
- A button on every video (with a mouse): pointing at a video or a
thumbnail shows a ⬇ Download button on it that opens that exact clip:
YouTube's player and its home, search and sidebar thumbnails, videos in X,
Reddit, Instagram, Facebook, Bluesky and 9GAG feeds, TikTok, Twitch and Bilibili
thumbnails. "Turn the buttons on videos on/off" in the userscript
manager's menu hides them.
- Feeds too: on TikTok's For You feed, X timelines and Bluesky the URL
doesn't change while you scroll, so the button takes the clip on screen when
you click it (it is briefly outlined). Nothing is looked up while you scroll.
- Phone-friendly: on small screens it is a round button you can drag to
either side, and the formats open as a bottom sheet.
- Real formats only: every quality comes from the actual source, with
NoBsDL's size estimate. Nothing is invented.
- Live progress: Queue → Download → Process → Ready, with a real
percentage while bytes flow (and while MP3 is encoded), speed and time left.
- Close it any time: the job keeps running, the button shows the
percentage and the file is still saved when ready.
- MP3 128 / 256 / 320 kbps next to the MP4 qualities.
- In your language: the panel follows the browser's language (English,
Simplified and Traditional Chinese, Russian, Ukrainian, Spanish,
Portuguese, French, German, Italian, Polish, Turkish, Indonesian,
Vietnamese, Japanese, Korean). Messages written by the NoBsDL server stay
as it sends them.
- Minimize to a small round button, or drag the button elsewhere; both
are remembered.
- Falls back to opening the matching NoBsDL page when your userscript manager
does not provide
GM_xmlhttpRequest.
NoBsDL's interaction promise applies to everyone: No popups. No forced
redirects. No fake download buttons. Just download.
Supported sites
Each link opens that site's downloader on nobsdl.com, which also works
without the script (paste a link there).
- YouTube videos — YouTube downloader
and YouTube to MP3. Mix/Radio links stay
single-video downloads.
- YouTube Shorts — YouTube Shorts downloader.
- YouTube playlists open the
YouTube playlist downloader
(pick items and format, ZIP).
- TikTok videos and mobile shortlinks — TikTok downloader.
- Instagram Reels and media posts — Instagram downloader.
- Public Facebook video and Reel pages — Facebook video downloader.
- Reddit video posts and direct
redd.it media links — Reddit video downloader.
- X/Twitter status pages containing media — X (Twitter) video downloader.
- SoundCloud tracks (MP3) — SoundCloud to MP3.
- Twitch clips and past videos, Bilibili videos, Dailymotion videos, Pinterest pins, Bluesky
posts, Streamable, Imgur, 9GAG, Odysee, Rutube and OK.ru video pages, plus
Bandcamp tracks and Mixcloud shows as MP3 — the
universal video downloader (each
verified with a real download).
Feeds: TikTok For You/Following, X/Twitter timelines and Bluesky were checked
on the live sites (2026-10-06). The same on-screen-clip detection is enabled
for Reddit, Instagram, Facebook, 9GAG and SoundCloud (now-playing track) but
was not yet checked live there (login walls or bot checks in the test
browser). On TikTok's mobile website some userscript managers can't read
which clip is playing; the panel then asks you to paste the clip's link
(Share → Copy link). YouTube, profiles and search pages show no feed button:
opening a video there changes the URL, and that page gets the button.
Free and Supporter
Most downloads are free. Some higher resolutions and files over the free size
limits (500 MB video, 100 MB MP3) need a paid
NoBsDL Supporter key; the panel shows those
choices with a lock and never starts them for a free session. This is
declared as @antifeature payment (on OpenUserJS, which has no payment
category, as @antifeature membership). A Supporter session activated on
nobsdl.com in the same browser is used when your userscript manager sends
nobsdl.com cookies with its requests; otherwise use Open on NoBsDL in the panel,
where your Supporter access works as usual. After you open the Supporter page
from the panel, coming back to the tab lists the same link's formats again (for
up to 2 hours), so a pass bought there shows at once; Already paid? Refresh
does the same by hand.
Privacy and permissions
@grant GM_xmlhttpRequest (+ GM.xmlHttpRequest) with @connect nobsdl.com
only: requests go to nobsdl.com and nowhere else. @grant GM_registerMenuCommand adds the on/off switch for the buttons on videos.- Nothing is sent until you open the panel. Then one public media URL is
sent to nobsdl.com to list its formats: the page's own, the one whose
button you clicked, or on a feed the clip on screen (read from the page
when you click). Choosing a format starts
the job and polls its status. Clips you merely scroll past are never looked
up.
- Requests may carry your normal nobsdl.com cookies (your userscript manager
decides), which is how an active Supporter session can be recognised. The
script itself stores no key, cookie or history; only whether you minimized
the button, where you dragged it, whether the buttons on videos are on,
and a count of saved files for a one-time rating note
(
GM_getValue/GM_setValue).
- No analytics, ads or tracking code in the script. The DOM is built with
text nodes only (no
innerHTML), inside a Shadow DOM.
- Links use
noopener, noreferrer and referrerPolicy="no-referrer".
The script does not bypass logins, private-media controls, paywalls or DRM.
Download only media you are allowed to save.

The browser suite fulfils every page and NoBsDL API answer in-process; it does
not contact media sites or NoBsDL. This repository is published from the
NoBsDL source tree by tools/userscript/publish.sh. Screenshots in media/ were taken on a
real YouTube page (Big Buck Bunny, CC-BY Blender Foundation) with the real
NoBsDL service; recommendations are blurred.
