YouTube Timestamp Link Generator

Create shareable YouTube links that start at an exact second, in 4 styles (short / full / embed / markdown). Build chapter descriptions that pass YouTube's auto-chapter rules. Free and private.

What is the YouTube Timestamp Link Generator?

YouTube Timestamp Link Generator does two related jobs. First, it parses any YouTube URL or 11-character video ID (regular watch URLs, youtu.be shorts, embed URLs, /shorts and /v paths) and lets you build a deep link that starts at any second — formatted as a short youtu.be URL, a full youtube.com/watch URL, an embed iframe URL, or a markdown link ready for blog posts. Second, it includes a multi-row chapter builder for the description box: add labels and timestamps, drag chapters into order, and the tool surfaces YouTube's auto-chapter requirements (first must be 0:00, minimum three chapters, each at least 10 seconds long) with live validation. Output is provided as both the plain-text description format YouTube parses and as a markdown list with clickable links for blogs and READMEs. Timestamps accept many formats — 1:23, 1:23:45, 85s, 1h2m3s — and the engine round-trips them safely.

How to use it

  1. Paste a YouTube URL or 11-character video ID into the field.
  2. Type your timestamp in any common format (1:23, 1h2m3s, 85s, …).
  3. Pick the link style — short, full, embed, or markdown.
  4. For chapters: add rows, label each segment, and copy YouTube's auto-chapter description.

Benefits

  • Parses every YouTube URL style: watch?v=, youtu.be/, /embed/, /shorts/, /v/.
  • Four link output styles in one tool — short, full, embed iframe URL, and markdown.
  • Multi-format timestamp parser: 1:23, 1:23:45, 85s, 1h2m3s.
  • Preserves playlist (?list=) when the input URL carries one.
  • Chapter builder validates YouTube's auto-chapter rules in real time.
  • Generates both plain-text (for the YouTube description box) and markdown (for blogs).
  • Reorder chapters with up/down buttons; persistence in localStorage.
  • Runs entirely in your browser — Toollyz has no server.

Frequently asked questions

What URL styles does it accept?

Standard watch URLs (youtube.com/watch?v=…), short URLs (youtu.be/…), embed URLs (/embed/…), /shorts/ URLs, and the legacy /v/ path. You can also paste a bare 11-character video ID directly.

What's the difference between the four link styles?

Short (youtu.be/ID?t=X) is the most concise. Full (youtube.com/watch?v=ID&t=Xs) is the canonical share URL. Embed adds ?start=X for use in iframes. Markdown wraps the link with [m:ss](URL) for blog posts.

What timestamp formats are supported?

Colon-style — 1:23 (m:s) and 1:23:45 (h:m:s) — and compound style — 85s, 2m30s, 1h2m3s. Mixed formats are detected automatically.

How do YouTube auto-chapters work?

YouTube reads the video description for lines starting with timestamps. If at least 3 timestamps appear (the first being 0:00) and each chapter is at least 10 seconds long, the player shows a chapter list. Toollyz validates these rules live.

Will the link preserve a playlist?

Yes. If your input URL has a `list=` parameter, the generated link includes it (toggleable in defaults).

Why is the markdown style useful?

It's ready to paste into a blog post or README — the rendered output is a clickable timestamp like '1:23' that opens the video at that moment.

Can I add unlimited chapters?

Yes. Add as many rows as you like — the validator warns you if any chapter is shorter than YouTube's 10-second minimum.

Does the embed URL respect autoplay?

It uses the standard `start=` parameter; combine it with `&autoplay=1` in your `<iframe>` if you want autoplay.

What about YouTube Shorts?

Shorts URLs are parsed correctly and the deep link still works — it just opens at the chosen second inside the Shorts player.

Is anything uploaded?

No. URL parsing and link composing are pure browser functions — Toollyz has no server that ever sees your URL.

Can I reorder chapters?

Yes — each row has up/down arrows. Reordering updates the description preview live.
