About YTChapterFix
YTChapterFix is a free online tool created to make YouTube chapter timestamps easier to manage.
Video creators often need to adjust timestamps after adding an intro, changing playback speed, removing clips, inserting new sections, or editing a finished video. Manually recalculating every chapter can take time and can easily lead to mistakes.
YTChapterFix is designed to solve that problem in one simple place.
With our tool, you can:
Clean and format YouTube chapter timestamps
Shift all timestamps forward or backward
Recalculate timestamps after changing playback speed
Adjust chapters after adding or removing sections
Check timestamps for common YouTube chapter requirements
Copy corrected timestamps for use in your video description
The tool is especially useful for YouTube creators, audiobook publishers, podcasters, educators, and anyone working with long-form video content.
Our Goal
Our goal is simple: provide a fast, easy-to-use tool that saves creators time and reduces manual timestamp calculations.
YTChapterFix is designed to work directly in your browser. You do not need to create an account just to use the main tool.
