– Businesses & Partners promoting products

Can You Add a Collaborator After Posting?

YES! In 2025, Instagram allows you to add a collaborator even after posting! Before, you had to delete and repost, but now you can invite someone after publishing without losing engagement.

How to Collaborate on Instagram After Posting (Step by Step)

Method 1: Add a Collaborator to an Existing Post (Easiest Way)

You can add a collaborator to an existing post in just a few taps. Here’s how:

1. Open Instagram and go to your post.
2. Tap the three dots (⋮) on the top right.
3. Select Edit from the menu.
4. Tap “Tag people” → then “Invite collaborator”.
5. Search for the Instagram user you want to collaborate with.
6. Tap “Invite” and wait for them to accept.
7. Once they accept, the post will appear on both profiles!

Tip: The collaborator must accept the request before the post is shared on their profile.

Method 2: Add a Collaborator to an Instagram Reel After Posting

Instagram Reels are super popular, and now you can add collaborators even after posting. By following these simple steps:

1. Go to your Instagram Reel.
2. Tap the three dots (⋮) in the bottom right corner.
3. Select Edit Reel → Invite Collaborator.
4. Search for the account you want to add.
5. Tap “Invite” and send the request.
6. Once they accept, the Reel will appear on both profiles.

Works for Reels, too! This means you don’t need to delete and re-upload anymore!

Method 3: Collaborate on an Instagram Video (IGTV or Regular Videos)

If you posted a video (not a Reel), you can still add a collaborator:

1. Open your Instagram video post.
2. Tap the three dots (⋮) and select Edit Post.
3. Choose Tag people → Invite collaborator.
4. Search for the user and tap Invite.
5. They will get a notification and must accept it.

After they accept, the video will be visible on both accounts.

Method 4: Collaborate on an Instagram Story After Posting

Instagram doesn’t let you edit Stories after posting, but here’s a trick:

Solution 1: Share the Story & Tag the Collaborator
 1- Open your Story.
 2- Tap More Options (⋮) → Share as Post.
 3- Follow Method 1 to add a collaborator.

Solution 2: Repost the Story with a Collaborator
If your Story is still live, you can:
1- Go to the Story.
2- Tap More (⋮) → Select “Share to Another Story”.
3- Tag the collaborator in the new Story.

This is the best workaround for Stories!

Why Can’t I Add a Collaborator After Posting? (Fixes & Solutions)

If you don’t see the option to invite a collaborator, try these fixes:

• Update Instagram – Make sure you have the latest version.
• Switch to a Professional/Creator account – Some features work better on these accounts.
• Check if the user follows you – Sometimes, Instagram limits collaboration with private accounts.
