How to Reverse YouTube Videos
When people search for "reversing YouTube videos" they usually mean one of two things: playing a series of videos in reverse order (oldest first), or literally playing one video backwards. Here is how to do both — and which one you probably want.
Reverse the order of videos (the common case)
If a channel or playlist shows its newest videos first and you want to start from the beginning, you want to reverse the list order. Paste the playlist (or a channel's uploads) into playlist.tools and sort by date, oldest first — the entire series now plays chronologically.
This works for any public playlist, including ones you do not own, and is the right fix for watching tutorials, vlogs, or lecture series from episode one.
Playing a single video backwards
YouTube has no built-in way to play one video's footage in reverse. If you genuinely need backwards playback (for music or visual effects), you would have to download the clip (where permitted) and reverse it in a video editor — that is an editing task, not a playback setting.
Most searchers actually want the first case: watching a series from the start. For that, reversing the playlist order takes seconds.
Keep your place once it's in order
After reversing, mark videos as watched and let your progress sync across devices so you can resume the series anywhere.
You can do all of this free on playlist.tools — paste any playlist URL and start sorting and tracking in seconds.
