What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
YouTube does not provide a documented one-click command to copy every video in one playlist into another. To make a separate destination playlist, create or open it and add the source videos individually with Save to playlist. If you only want to find the original playlist later, use Save playlist instead; that bookmarks the playlist in your library rather than copying its contents.
Save a playlist or copy its videos?
These are different actions. Saving another creator’s playlist adds that playlist to your YouTube library so you can return to it. It does not create a new playlist filled with the same videos. To build a distinct playlist, you need to add its videos to the destination playlist one by one, or use the YouTube Data API to automate those individual additions.

Save the original playlist to your library on a computer
- Open a video that belongs to the playlist you want to keep.
- Select the source playlist in the panel beside the video.
- Click Save playlist. YouTube’s computer instructions for saving playlists describe this as adding the playlist to your library.
This keeps the original playlist as the saved object; it does not make a separate copy of its video entries.

1. Create or open the destination
Create the playlist you want to fill, or open an existing one. You can add videos to a playlist you own; the destination picker lets you choose it when saving a video.

YouTube’s playlist instructions for Android document saving individual videos and note that options can vary by platform. YouTube also publishes separate instructions for computer, Android, iPhone and iPad, and mobile web, so the exact control or library location may differ by device.
What may not transfer
Do not assume every entry can be added. A video may be private, unavailable, or inaccessible to your account. YouTube also notes that some made-for-kids videos or channels cannot be added from a homepage, though you may be able to add content from search results. If an item will not save, try locating it through search and using its Save control there; if it remains unavailable, it cannot be added from your account in that state.

Let other people add videos to the destination
If the goal is to build a playlist with someone else, make the destination a collaborative playlist and invite them. Invited collaborators can add videos using the playlist’s Add control. This shares editing of the destination; it does not import or merge another playlist automatically. See YouTube’s collaboration instructions for the invitation workflow.
Automate the copy with the YouTube Data API
For a developer, a script can list the source playlist items and insert each video into the destination separately. The API documentation describes item-level operations, not a whole-playlist copy endpoint. This route requires OAuth authorization and an application configured to use the YouTube Data API.

How the API workflow works
- Call playlistItems.list for the source playlist and collect the video IDs from its items.
- Follow every
nextPageTokenuntil the list is exhausted. A list request can return at most 50 results, so a script must handle pagination. - For each accessible video, call playlistItems.insert with the destination playlist ID in
snippet.playlistIdand the video’s resource ID. The request requires OAuth authorization. - Record failures and check the destination for missing entries. Private, deleted, or otherwise inaccessible videos may not be available to the authenticated account; handle duplicates deliberately rather than assuming every insert will be unique.
Each documented insert costs 50 quota units. Listing has its own documented quota cost, and the list reference explains pagination and the 50-result maximum: PlaylistItems: list. Account for quota before running a large job. This is a technical automation route, not a built-in consumer bulk-copy button.
