Why Socialync for Instagram to YouTube
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?
Yes. Socialync publishes to both Instagram Reels and YouTube Shorts simultaneously from one upload. You can write an Instagram caption and a YouTube SEO title separately, plus customize tags and descriptions.
Are Instagram Reels and YouTube Shorts the same format?
Yes. Both use 9:16 vertical at 1080×1920, and both run up to 3 minutes, so the same file works on both.
Can I post the same video on YouTube and Instagram?
Yes. Neither platform penalizes you for posting your own video in both places. Upload the original file to each one rather than a downloaded copy: Instagram says it shows watermarked or low resolution reels to fewer people, and YouTube wants to see that you made the video.
