How to Make an Instagram Carousel in PostNitro
- Start from a topic, a link or your own text. Type a topic, paste an article URL or an X thread, or bring slide-by-slide copy. AI writes and lays out the deck on your brand kit.
- Finish it in the freeform editor. Pick 4:5 or 1:1, then drag, resize and layer anything. An image can run across two slides, so the swipe feels continuous.
- Publish or export. Schedule it to your feed (and story) from Creator+, or download the slides and post them yourself.
Instagram Carousel FAQ
The editor
A design tool built for one shape
Not a general canvas with a carousel preset bolted on. The editor is built around the 4:5 slide sequence — templates, curated font pairings, brand-kit colours and your own images, with the platform safe zones already accounted for.
From a blank slide to a scheduled post without leaving the editor.
