YouTube Video ID Extractor

About the YouTube Video ID Extractor

This tool does one job: reading a messy YouTube link and returning the plain 11-character ID underneath it, nothing else. For a standard watch link the ID is read straight from the v query parameter using the browser's own URL parser, so it doesn't matter what order the parameters come in or how many extra ones (list, index, si, t, and so on) are tacked on before or after it. For youtu.be short links, embed links, Shorts links, and the m.youtube.com mobile domain, the ID is read from the path itself instead of the query string. It's a narrower cousin of the YouTube Thumbnail Grabber below, that tool hands you downloadable image files in five sizes, this one hands you the raw ID and the handful of URLs built from it (watch link, embed link, thumbnail link) so you can drop it into an oEmbed call, an iframe, or your own script.

A more robust parsing technique than its sibling Thumbnail Grabber

This site's YouTube Thumbnail Grabber matches watch links with a hand-written regex, [?&]v=([a-zA-Z0-9_-]{11}), that scans the raw string directly. This ID extractor instead hands the whole input to the browser's real URL constructor and reads the video ID out with url.searchParams.get("v"), letting the browser's own query-string parser handle the splitting. That's a more robust technique: it correctly reads the v parameter no matter where it falls among any number of other tracking parameters, without needing a regex that anticipates every possible surrounding character.

Hostname normalization explicitly supports the mobile and privacy-embed domains

Before checking which YouTube domain a link belongs to, this tool strips a leading www. or m. from the parsed hostname, and it separately recognizes youtube-nocookie.com — the privacy-enhanced embed domain many CMS platforms and GDPR-conscious sites use — as a fully valid alternative to the standard youtube.com domain. Both of those are handled deliberately and explicitly here, rather than depending on a broader pattern happening to match them by coincidence.

One additional path format is recognized here that its sibling tool doesn't support

Alongside /embed/ and /shorts/, this extractor also recognizes YouTube's /live/ path format used for premiere and livestream links, matched with a single combined pattern: /^\/(embed|shorts|live)\/([a-zA-Z0-9_-]{11})/. The Thumbnail Grabber's separate pattern list doesn't include a /live/ case at all, making this tool the more complete of the two when it comes to the range of link shapes it correctly recognizes.

A trailing slash on the URL doesn't break the match

The extracted pathname has any trailing slashes stripped with path.replace(/\/+$/, "") before being tested against the path patterns, so a link like youtube.com/embed/dQw4w9WgXcQ/ — with an extra slash some copy-paste sources tack onto the end — still resolves correctly instead of silently failing to match because of one stray trailing character.

Four ready-made derived links are generated from the single extracted ID

Once an ID is found, the tool immediately builds a canonical watch URL, an embed URL, a shortened youtu.be URL, and a thumbnail image URL, all from that one ID, and displays them together with a live preview image. That's this tool's specific value beyond the Thumbnail Grabber: rather than offering thumbnails in five resolutions, it hands you the clean ID itself plus the handful of standard URL formats built from it, ready to drop into an iframe, an oEmbed request, or your own script.

The Copy ID button is guarded against copying an empty or stale result

The Copy ID button checks a stored currentId variable before doing anything, and does nothing at all if it's empty — which happens whenever the most recent extraction attempt failed. That prevents accidentally copying a blank value or a leftover ID from a much earlier successful extraction if the input was later changed to something invalid without re-running the extractor.
