Why Socialync for Instagram to YouTube

1

Upload once, post to both

Drop a video into Socialync. We publish to Instagram and YouTube at the same time, so you post to YouTube and Instagram simultaneously without copy-paste.

Both support 9:16 vertical

Reels and Shorts both prefer 1080×1920 vertical. The same source video works on both.

YouTube needs an SEO title, Instagram needs a story caption

YouTube discovery is search-based. Instagram is algorithmic. Write a keyword-rich YouTube title and a storytelling Instagram caption 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 YouTube at the same time?

Are Instagram Reels and YouTube Shorts the same format?

Yes, both use 9:16 vertical at 1080×1920. YouTube Shorts caps at 60 seconds; Instagram Reels go up to 90. Trim if needed.
