To post one Reddit post in another subreddit, use Reddit’s crosspost feature. Open the original post, tap or click Share , then choose Crosspost or Community , select the target subreddit, edit the title if needed, and hit Post.

Desktop

  1. Open the post you want to share.
  2. Click Share under the post.
  3. Select Crosspost.
  4. Pick the subreddit you want.
  5. Add flair or adjust the title if the subreddit allows it.
  6. Click Post.

Mobile

  1. Open the post in the Reddit app.
  2. Tap Share.
  3. Choose Community or Crosspost.
  4. Select the subreddit.
  5. Edit the title if needed.
  6. Tap Post.

Important

  • Some subreddits do not allow crossposting.
  • You usually need to follow that subreddit’s rules, including flair and content restrictions.
  • If crossposting is unavailable, you can instead share the original post link in a new post, if the community permits it.

Example

If you found a useful post in one subreddit and want it seen in another, crossposting keeps the original source attached instead of reuploading the content.

TL;DR: Use Share → Crosspost/Community → choose subreddit → Post.
