See Instagram to Facebook cross-posting in action
Share content on Instagram and Facebook from one upload. Watch Socialync handle formatting, captions, and scheduling automatically.
Why Socialync for Instagram to Facebook
Upload once, post to both
Drop a video into Socialync. We publish to Instagram and Facebook at the same time, so you post to Facebook and Instagram simultaneously without copy-paste.
Both support 9:16 Reels and standard formats
Instagram Reels and Facebook Reels both prefer 1080×1920 vertical. Standard posts work in 1:1 and 4:5.
Caption tone shifts between platforms
Instagram audiences respond to visual storytelling. Facebook audiences respond to community-driven conversation. Write each separately.
Trusted by creators and businesses
Join thousands of people who stopped manually reposting.
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 post to Instagram and Facebook at the same time?
Yes. Socialync publishes to both Instagram and Facebook simultaneously from one upload. You can customize captions, hashtags, and scheduling per platform.
Should I use Meta's built-in cross-post feature instead?
Meta's native cross-post forces identical captions on both platforms, which underperforms. Socialync gives you separate fields per platform so you write audience-tuned copy for each.
Do Instagram and Facebook use the same video format?
Yes, both support 9:16 vertical Reels at 1080×1920. Standard posts work in 1:1 and 4:5. The same source file works on both.
