How to Federate a Quote Repost From Threads to Mastodon

When you share a post from Threads with a quote, you may want that quote repost to appear on Mastodon as well. Federating quote reposts requires specific settings and a manual step because Threads and Mastodon handle quote posts differently. This article explains the exact steps to make your quote repost visible on Mastodon and other ActivityPub servers.

Why Quote Reposts from Threads Appear Differently on Mastodon

Threads uses its own internal quoting system that is not natively compatible with Mastodon’s quote mechanism. Mastodon does not support inline quote posts the way Threads does. When you quote a post on Threads, that quote does not automatically appear as a quote on Mastodon. Instead, the text you wrote in the quote shows up as a regular post, and the original post you quoted is not attached.

For the quote repost to be useful on Mastodon, you must include a link to the original Threads post within your quote text. Mastodon users can then click that link to see the original content. Without the link, Mastodon followers see only your commentary with no context.

The federation feature itself must be enabled on your Threads profile. This setting allows your public posts to be distributed to other ActivityPub servers, including Mastodon instances. If federation is off, no posts — including quote reposts — leave Threads.

Steps to Federate a Quote Repost from Threads to Mastodon

1. Enable Fediverse sharing on your Threads profile
   Open Threads and go to Profile > Privacy > Fediverse sharing. Toggle the switch to ON. You must confirm by tapping the confirmation button. This allows your public posts to be shared with Mastodon and other ActivityPub services.
2. Set your post visibility to Public
   Before you create the quote repost, ensure your account is set to Public. Go to Profile > Privacy > Private profile and make sure it is OFF. Only public posts can federate.
3. Find the post you want to quote
   Locate the post on Threads that you want to share with a comment. Tap the repost icon (two arrows forming a square) on that post.
4. Select Quote and write your text
   From the menu that appears, choose Quote. A new compose window opens with the original post shown above your text area. Write your commentary in the text field.
5. Add a direct link to the original post in your text
   Copy the URL of the original Threads post. You can get the URL by tapping the share icon on the original post and selecting Copy link. Paste that link into your quote text, ideally at the end of your commentary. This link is necessary because Mastodon will not display the quote as a quote.
6. Post your quote repost
   Tap the Post button. Your quote repost is now live on Threads. Within a few minutes, it will appear on Mastodon as a regular post containing your text and the link you included.

Common Issues with Quote Repost Federation

My quote repost did not appear on Mastodon at all

Check that Fediverse sharing is enabled under Profile > Privacy > Fediverse sharing. Also confirm your account is set to Public. If both settings are correct, wait up to 15 minutes for the post to propagate. Mastodon servers poll Threads periodically, so there can be a delay.

Mastodon shows only my text, not the original post

This is expected behavior. Mastodon does not support Threads-style quote posts. The only way to provide context is to include the link to the original post in your quote text. If you forgot to add the link, delete the quote repost from Threads and repost it with the link included.

My followers on Mastodon cannot see the linked post

Ensure the original post you quoted is also public. If the original poster has a private account or has restricted visibility, Mastodon users may not be able to view it. The link will still open in a browser, but the content may be hidden behind a login wall.

Threads Quote Repost vs Mastodon Quote Post

Item	Threads Quote Repost	Mastodon Quote Post
Federation support	Quote text federates as plain post	Quote is native to Mastodon
Original post attachment	Not attached automatically	Original post embedded
Visibility requirement	Public account and public post	Public or followers-only
Workaround needed	Manually paste link to original	None needed

Now you can create quote reposts on Threads that your Mastodon followers can understand and engage with. Remember to always paste the link to the original post in your quote text. For best results, keep your quote text brief and place the link at the end so Mastodon users see the context first.
