Cross-Posting Guide
Post to Instagram and Threads from one upload
Reels for visual reach, Threads for conversation. Two Meta platforms, one workflow.
Quick answer: To post to Instagram and Threads at the same time, use Socialync. Upload your video once, pick Instagram and Threads, write a caption for each, then post now or schedule it. Both go live at the same moment. Posts you make in the Instagram app stay on Instagram, so post from Socialync when you want both. It's free for 5 posts a month with no credit card.

The multi-platform posting is seamless. My content reaches 3x more people with zero extra effort.
Simple dashboard, easy sign-up, and the scheduling is so nice. If I make 10 videos in one day I can schedule them to all platforms weeks in advance. Goated!
I built this because I was burning out posting manually. Now I post in 3 minutes instead of 45.

Frequently asked questions
Can I cross post Instagram to Threads?
Yes. Socialync publishes to both simultaneously with separate caption fields. Both platforms benefit from the same visual asset.
Does Meta auto cross post Instagram to Threads?
Meta has a toggle that auto shares Reels to Threads as a link card. Socialync's native dual publish is more flexible and produces better Threads engagement.
Will posts I make in the Instagram app copy over to Threads?
No. Socialync publishes what you make in Socialync. It can't see posts made in the Instagram app, including ones already up. Make the post in Socialync, pick Instagram and Threads, and it goes to both at once. To bring over something already on Instagram, upload the original file to Socialync and pick only Threads.
