How it works

How YouTube Playlist Tools Works

YouTube Playlist Tools uses public playlist metadata to calculate total duration, video count, average video length, speed-adjusted watch time, playlist links, and CSV exports.

1. You paste a playlist URL or ID

The tool extracts the playlist ID from the URL. For ID-only tools, this parsing happens locally in the browser without calling YouTube.

2. Public playlist metadata is requested

For duration, link extraction, and CSV export, the server asks YouTube for public playlist items and available video duration metadata.

3. Durations are totaled

Available video durations are converted to seconds, added together, and formatted as hours, minutes, and seconds. Speed estimates divide the same total by playback speed.

4. Unavailable videos are handled separately

Private, deleted, region-blocked, or unavailable videos may appear in playlist data, but they cannot add duration unless YouTube returns their duration metadata.
