When you post on Threads, the app may automatically share that post to Instagram as a story or feed update. This cross-posting feature is enabled by default for many users, and it can clutter your Instagram timeline with content meant only for Threads. The cause is a linked sharing toggle inside the Threads composer that sends posts to Instagram every time you publish. This article explains how to turn off that toggle permanently so your Threads posts never appear on Instagram again.
Key Takeaways: Permanently Stop Threads-to-Instagram Cross-Posting
- Threads composer toggle: Turn off the Instagram share icon before each post to prevent a single cross-post.
- Settings > Account > Sharing to Instagram: Disable the automatic sharing option to stop all future cross-posts without manual toggling.
- Instagram connected accounts: Unlink your Instagram from Threads in the app settings to remove the sharing permission entirely.
What Is Cross-Posting From Threads to Instagram?
Cross-posting is a built-in feature that copies your Threads post and publishes it as an Instagram story or a feed post. When you compose a new Threads post, a small share icon appears near the Post button. If that icon is highlighted, the post will also appear on Instagram. The feature is designed to let you share content across both platforms with one tap, but many users find it unwanted when they want to keep Threads conversations separate from their Instagram audience.
The sharing uses the connection between your Threads account and your Instagram account. Because Threads requires an Instagram login, the two accounts are linked by default. The cross-posting toggle leverages that link to push content automatically. There is no separate permission screen — the toggle alone controls the behavior.
Prerequisites for Disabling Cross-Posting
You need an active Threads account logged in on the mobile app (iOS or Android). The Instagram account linked to that Threads account must be the same one you want to stop sharing to. You do not need to uninstall or reinstall either app. All changes are made inside the Threads app settings or during post creation.
How to Turn Off Cross-Posting Permanently
There are two methods to disable cross-posting. The first method stops it for all future posts by changing a global setting. The second method removes the Instagram connection entirely, which also prevents any future cross-posting. Use the method that fits your needs.
Method 1: Disable the Automatic Share Setting
- Open the Threads app
Launch Threads on your iPhone or Android device. Make sure you are logged in to the account that is cross-posting. - Go to your profile
Tap the profile icon at the bottom-right corner of the screen. This opens your profile page. - Open settings
Tap the two horizontal lines icon at the top-right corner of the profile page. A menu appears. - Select Account
In the menu, tap Account. This opens account-related settings. - Tap Sharing to Instagram
Scroll down and tap Sharing to Instagram. You see a toggle labeled Share Threads posts to Instagram. - Turn off the toggle
Tap the toggle so it changes from blue or green to gray. This disables automatic sharing for all future posts. Any new post you create will not be sent to Instagram unless you manually enable the toggle in the composer.
Method 2: Unlink Instagram From Threads
If you want to remove the connection completely, follow these steps. This method also stops cross-posting permanently, but it may affect other features that rely on the Instagram link, such as finding friends.
- Open Threads settings
Go to your profile, tap the two horizontal lines icon, and tap Account. - Tap Linked accounts
Under Account settings, tap Linked accounts. You see your Instagram handle listed. - Tap Unlink
Tap the Instagram handle, then tap Unlink. A confirmation dialog appears. - Confirm the unlinking
Tap Unlink again. Your Threads account is now disconnected from Instagram. Cross-posting will no longer work because there is no target account to share to.
If Posts Still Appear on Instagram After Disabling
Sometimes the setting change does not take effect immediately, or a cached post queue still sends content. Here are the most common reasons and their fixes.
Posts Scheduled Before the Setting Change
If you drafted a Threads post before turning off the sharing toggle, that post may still have the share option enabled. The setting change applies only to new posts created after the toggle was turned off. Delete the scheduled draft and create a fresh post.
Instagram Story Cross-Posting Still Active
The Sharing to Instagram setting controls feed posts and stories together. If stories still appear, open the Instagram app and go to your profile. Tap the three-line menu, then tap Settings > Privacy > Story. Under Sharing, turn off Share to Facebook and any other cross-posting options. This does not affect Threads, but it ensures Instagram is not pulling content from other linked sources.
App Cache Causing Stale Settings
If the toggle is off but posts still cross-post, clear the Threads app cache. On Android, go to Settings > Apps > Threads > Storage > Clear cache. On iOS, offload the app: Settings > General > iPhone Storage > Threads > Offload App, then reinstall. This forces the app to reload the latest settings.
Threads Cross-Posting vs Manual Share: What Changes
| Item | Automatic Cross-Posting | Manual Share (No Cross-Posting) |
|---|---|---|
| How it works | Every new post is sent to Instagram without extra taps | You must tap the share icon in the composer to send a post to Instagram |
| Global setting needed | Toggle in Settings > Account > Sharing to Instagram must be ON | Toggle in Settings > Account > Sharing to Instagram must be OFF |
| Post-by-post control | No — all posts share automatically | Yes — you choose which individual posts to share |
| Instagram account link required | Yes — accounts must be linked | Yes — accounts must be linked for manual share to work |
| Best for | Users who want every Threads post on Instagram | Users who want Threads and Instagram to remain separate |
After you disable the automatic sharing toggle, your future Threads posts will stay in Threads. If you ever want to share a specific post to Instagram, you can turn the share icon on in the composer for that single post. The global setting remains off, so the change is permanent until you manually re-enable it. For extra security, unlink the accounts entirely — this removes the possibility of cross-posting even if the toggle is accidentally turned on later.
