It’s very easy to post your Instagram content on other social networks, including Facebook (which usually doesn’t allow other apps to post in its personal feed, but for Instagram it made an exception). If you don’t know how to do it yet, we will show it to you now.
Here is how you do it using Instagram app on your iPhone (it’s almost the same for Android):
First, you’ve got to connect your accounts on two different platforms. Go to your profile, tap the button at the top right corner. Go to Settings, tap Account, then go to Linked Accounts. Then choose the platform you want to connect your Instagram account with.
Now, while adding new content on Instagram, you can choose linked networks to which you want to post as well.
