YouTube Timestamp & Chapter Generator

Create timestamp links that open a YouTube video at a specific moment, or prepare a formatted chapter list for your video description. Use this generator to organize timestamps, check chapter formatting, and copy the result for use in YouTube Studio.

You can create a timestamp link or generate a chapter list without a YouTube API key.

Create a YouTube Timestamp Link

A YouTube timestamp link lets you share a specific moment in a video instead of asking viewers to find it manually.

  1. Paste a supported YouTube video URL.
  2. Enter the desired start time in the supported timestamp format.
  3. Optionally enter the known video duration to check that the start time is within the video.
  4. Generate the timestamp link, then copy or open it to test the result.

For example, a start time of 05:30 points to five minutes and thirty seconds into the video. Duration validation uses the duration you enter; the tool does not retrieve it automatically.

Generate YouTube Chapters

Chapters divide a video into named sections so viewers can navigate to the topics they want to watch.

  1. Enter a timestamp for each section and add a short, descriptive title.
  2. Start the first chapter at 00:00.
  3. Keep timestamps in ascending chronological order.
  4. Include at least three timestamps and make each chapter at least 10 seconds long.
  5. Optionally enter the known video duration and review any validation warnings.
  6. Generate and copy the formatted chapter list.

Example output:

00:00 Introduction
02:15 Main Features
05:40 How to Use
08:30 Tips and Tricks

Paste the finished text into your video description in YouTube Studio and save your changes there.

YouTube Chapter Formatting Rules

YouTube documents the following requirements for manually created video chapters: the first timestamp starts at 00:00, the list contains at least three timestamps in ascending order, and each chapter is at least 10 seconds long.

Use MM:SS for videos under one hour and HH:MM:SS for longer videos. Pair each timestamp with a clear, descriptive chapter title. Meeting these formatting checks does not guarantee that YouTube will display chapters; platform eligibility and other conditions may apply.

Supported YouTube URL Formats

The timestamp link generator accepts common YouTube video URL formats, including standard watch URLs, youtu.be links, Shorts URLs, embed URLs, and live URLs. Paste a valid video URL and review the generated link before sharing it.

No YouTube API Key Required

The tool extracts the video ID from the URL in your browser and generates the timestamp link or chapter text locally from the information you enter. It does not require a YouTube API key for these workflows.

The tool does not automatically retrieve video duration. If you want duration validation, enter the known duration manually. It does not edit or publish the video description for you.

Optional Video-Duration Validation

If you know the YouTube video duration, enter it in MM:SS or HH:MM:SS format. The tool can check timestamps against the duration you supply and warn about timestamps beyond the video or a final chapter with insufficient remaining duration.

This check is optional. The tool does not automatically fetch duration metadata because it is designed to work without the YouTube Data API or YouTube page scraping.
