Why you'd want to connect Facebook and Instagram
Connecting Facebook to Instagram lets you manage both accounts from one place, cross-post content between them, and see performance data for both platforms together. If you run a business or creator account, this saves time — you can write one caption and push it to both feeds instead of logging in twice.
The connection also lets you use Facebook's ad tools to promote Instagram posts, and Instagram's tools to promote Facebook content. You'll see which platform drives more engagement for the same post, which helps you decide where to spend your effort.
The technical requirement is that both accounts must be linked to the same Facebook Business Account or personal Facebook account. If you're using separate logins for each platform right now, you'll need to connect them first.
Key Takeaways
- Both accounts must be linked to the same Facebook Business Account or personal Facebook account before you can cross-post or manage them together.
- On Instagram, go to Settings > Accounts Center > Add Account and select Facebook to link the two.
- Once linked, you can cross-post from Instagram to Facebook using the sharing toggle when you create a post.
- If you already have a Facebook Business Account, you can add an existing Instagram account to it through Facebook's Business Suite.
- Disconnecting is simple — go to Accounts Center settings and remove the account you want to unlink.
Connecting a personal Instagram account to Facebook
Open Instagram on your phone and tap the menu icon (three horizontal lines) in the bottom right. Go to Settings and Privacy, then tap Settings. Scroll down and tap Accounts Center.
If this is your first time using Accounts Center, tap get your free guide. You'll see an option to add an account. Tap Add Account, then select Facebook. Log in with your Facebook credentials when prompted. Instagram will show you which Facebook account it found — if that's the right one, confirm it. If you have multiple Facebook accounts, you can choose which one to link.
Once linked, you can cross-post to Facebook whenever you create an Instagram post. When you're about to share a photo or video, look for the toggle that says "Also share to Facebook" or "Share to Facebook" — it's usually near the bottom of the screen before you hit Share. Toggle it on, and your post will go to both platforms at the same time.
Connecting a business or creator account using Facebook Business Suite
If you manage a Facebook Business Account and want to add an Instagram account to it, the fastest route is Facebook Business Suite. Go to business.facebook.com and log in with your Facebook account.
Click the menu icon (three horizontal lines) in the top left and select Settings. Under Accounts, click Instagram Accounts. Click Add Instagram Account. You'll see two options: connect an existing Instagram account or create a new one. If you already have an Instagram account, select Connect Existing Account and log in with that account's username and password.
Facebook will ask for permission to manage your Instagram account. Review what permissions you're granting — typically this includes the ability to post, respond to messages, and view insights. Click Authorize or Confirm, depending on what Instagram shows you. Once authorized, your Instagram account will appear in Business Suite, and you can manage both Facebook and Instagram from the same dashboard.
Cross-posting from Instagram to Facebook
After your accounts are linked, cross-posting is built into the Instagram app. When you create a post — a photo, video, or carousel — you'll see sharing options before you hit the final Share button. Look for a toggle or checkbox labeled "Also share to Facebook," "Share to Facebook," or sometimes just "Facebook."
Toggle it on. Instagram will show you which Facebook page or profile it will post to. If you have multiple Facebook pages, you can tap to choose a different one. The post will use the same caption, photo, and video you wrote for Instagram, though Facebook may crop or resize it slightly depending on the format.
One thing to know: if your Instagram post includes music from Instagram's music library, that music won't transfer to Facebook. The post will still go through, but without the audio. If you're posting a Reel with music, Facebook will post it as a video but may mute the audio or show a copyright notice depending on the track.
Managing insights and performance across both platforms
Once your accounts are linked, you can see performance data for both in one place. In Instagram, go to your profile and tap Insights (if you have a business or creator account). You'll see metrics like reach, impressions, and engagement for your Instagram posts.
To see how the same post performed on Facebook, open Facebook Business Suite and go to the Insights section. You can filter by date range and see which posts got more engagement on which platform. This helps you understand whether your audience is more active on Instagram or Facebook, and where to focus your content.
If you cross-post regularly, you'll notice that the same content often performs differently on each platform. Instagram users might engage more with Reels, while Facebook users might prefer carousel posts. Over time, this data tells you which formats work best for each audience.
Disconnecting Facebook from Instagram
If you want to unlink your accounts, the process is straightforward. On Instagram, go to Settings and Privacy > Settings > Accounts Center. You'll see both your Instagram and Facebook accounts listed. Tap the Facebook account and select Remove Account. Instagram will ask you to confirm — tap Remove again.
Once removed, you won't be able to cross-post to Facebook from Instagram anymore. Any posts you've already shared to both platforms will stay on both — disconnecting only stops future cross-posts. If you want to remove a specific post from Facebook, you'll need to delete it from Facebook separately.
If you linked through Facebook Business Suite instead, go to business.facebook.com, click Settings > Accounts > Instagram Accounts, find the account you want to remove, and click Remove.
Troubleshooting common connection problems
If you see an error message when trying to link your accounts, the most common cause is that you're trying to connect two accounts that don't share the same Facebook Business Account. Each Instagram account can only be linked to one Facebook account. If you've already linked this Instagram account to a different Facebook account, you'll need to remove it there first before linking it to a new one.
Another issue: if you changed your Facebook password recently, Instagram might not recognize the connection. Log out of both apps completely, clear your phone's app cache (go to Settings > Apps > Instagram > Storage > Clear Cache), and log back in. This usually fixes authentication problems.
If cross-posting isn't working even though your accounts are linked, check that you have a business or creator account on Instagram, not a personal account. Personal accounts can link to Facebook but have fewer cross-posting features. You can switch to a creator or business account in Instagram Settings > Account Type.
Frequently Asked Questions
Can I link multiple Instagram accounts to one Facebook account?
Yes. In Facebook Business Suite, you can add multiple Instagram accounts to the same Facebook Business Account. Each one will appear separately in your dashboard, and you can manage them all from one place. This is useful if you run multiple Instagram accounts for different brands or purposes.
What happens to my posts if I disconnect my accounts?
Posts you've already shared to both platforms stay on both. Disconnecting only stops future cross-posts. If you want to remove a specific post from one platform, you'll need to delete it there manually — disconnecting the accounts won't do that for you.
Can I cross-post from Facebook to Instagram?
Not directly through the same toggle. You can share Facebook posts to Instagram Stories, but you can't automatically post a Facebook feed post to your Instagram feed. The cross-posting feature works one way: from Instagram to Facebook. If you want the same content on both feeds, you'll need to post to Instagram first and use the cross-post toggle, or post separately to each platform.
Do I need a Facebook Business Account to link Instagram?
No. You can link a personal Instagram account to a personal Facebook account. However, if you want to use Facebook Business Suite or access advanced features like scheduling posts or detailed insights, you'll need to convert to a business or creator account on Instagram and set up a Facebook Business Account.
Why isn't the cross-post toggle showing up on my Instagram posts?
The toggle only appears if your accounts are linked and you have a business or creator account on Instagram. If you have a personal account, switch to a creator or business account first. Go to Settings > Account Type and select Creator or Business. After you switch, the cross-post option should appear the next time you create a post.
