LinkedIn carousels on Instagram: what actually transfers
! LinkedIn carousels require a resize tool to become Instagram carousels — they're different aspect ratios
+ ! Links in Instagram captions are not clickable, unlike LinkedIn
+ ! Professional tone on LinkedIn doesn't match Instagram's more personal, visual-first feed
+ ! No native integration between LinkedIn and Instagram for automatic cross-posting

What You Need to Know
How creators crosspost LinkedIn posts to Instagram
The most common workflow: screenshot or export your LinkedIn post as an image (several tools like Contentdrips do this), then post it as an Instagram feed post or Story.
For carousels, creators use Canva to rebuild the slides at 1080x1080 or 1080x1350.
For video content, they trim the LinkedIn video to under 60 seconds for Reels.
The caption gets rewritten — shorter, more personal, with a call to action pointing to the bio link instead of an inline URL.
This process takes 15-30 minutes per post when done manually.
Do it daily and it compounds into hours of overhead.
Make your Instagram posts look like they belong there
Instagram Reels rewards hooks in the first 3 seconds and content that keeps people watching to the end.
Feed posts perform best with high-contrast visuals and a caption that opens with a strong first line before the 'more' cut.
Stories disappear after 24 hours — use them for time-sensitive repurposes of LinkedIn content.
Hashtags on Instagram still matter but 3-5 targeted ones outperform 30 generic ones.
Your tone should shift from 'professional insight' to 'here's something useful I learned' — same information, warmer delivery.
