Why Socialync for Instagram to X

1

Upload once, post to both

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

X supports native photo, video, and GIF uploads

Do not link to your Instagram post. Upload native media to X. Native uploads get up to 6x more engagement than links.

Caption lengths are very different

Instagram allows 2,200 characters of storytelling. X caps at 280 with commentary. Write each separately.

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 X at the same time?

Yes. Socialync publishes to both Instagram and X simultaneously from one upload. Both get native media, and you can write a longer Instagram caption and a shorter X tweet separately.

Should I link to my Instagram post on X?

No. X downgrades external links. Upload the media natively to X for full reach. Socialync uploads native to both platforms automatically.

How long can a tweet be vs an Instagram caption?

X tweets cap at 280 characters. Instagram captions allow up to 2,200 characters. Write a tight 280-char take for X and a longer story for Instagram.
