What You Need to Know
How creators crosspost Instagram Reels to LinkedIn today
Standard manual workflow: save the original Reel video before uploading to Instagram (the cleanest approach), upload to LinkedIn as a native video, write a LinkedIn-appropriate caption that leads with professional insight rather than an entertainment hook, publish.
Make your LinkedIn video look professional
Three adjustments convert a Reel into a LinkedIn post worth watching.
