What You Need to Know
How creators crosspost Instagram content to X today
Two approaches work in practice.
Make your tweets land, not just post
X is a conversation platform.
Three things separate an Instagram post adapted well for X from one that falls flat.
Skip the manual work with PostOnce
PostOnce connects Instagram and X and posts native media automatically.
When you publish on Instagram, PostOnce picks up the image or video and posts it to X as a native upload — not a link card.
The media plays in the X feed.
