About YouTube timestamp / chapter generator
Build YouTube chapter blocks and deep links with ?t= seconds from a video URL and timestamp list.
This youtube timestamps stays in the tab. Nothing is uploaded to ihateonlinetools.com for the calculation. That is the same offline promise as the rest of the site: your numbers, caption, or recipe never need to sit in a third-party form log.
Enter a video URL or eleven-character id plus lines of timestamp and label. The tool emits clickable deep links with t= seconds and a chapter block. If your list does not start at 0:00, an Intro line is prepended so YouTube can auto-detect chapters.
Parsing accepts m:ss and h:mm:ss as well as raw seconds. Nothing is uploaded to YouTube from this page; you paste the block into Studio yourself. Related tools on this site cover nearby jobs without forcing a signup wall.

Is youtube timestamps free and offline-capable?

Why this one doesn't upload your file

Your file is read from disk into memory, processed, and handed back as a download. Once the page has loaded you can disconnect from the network entirely and it keeps working. The longer explanation
