Carousel Maker
One idea, a few slides, every slide on brand.
Make Instagram carousels as PNG slides and LinkedIn carousels as a PDF, written from your brand profile.
Examples
Instagram carousel maker example
Four slides of one carousel: hook, figure, list and call to action. Made with OpenPromo’s templates for Crumb & Co, a fictional bakery.

How it works
How the carousel maker works
- 1
Start from an idea
A tip list, a launch or a how-to. The writer plans one point per slide.
- 2
Slides get layouts
The first slide is the hook, the last is the call to action, and the middle ones use list, big-number or picture layouts.
- 3
Edit slide by slide
Change text, layout or picture on any slide with a live preview. Add or remove slides.
- 4
Render PNGs and a PDF
You get one PNG per slide for Instagram and one PDF for a LinkedIn document post.
What you can do
AI carousel generator features
LinkedIn carousel generator
The PDF is ready to upload as a LinkedIn document post.
Square or portrait
Slides in 1:1 or 4:5. Switch size and render again.
One look across slides
Every slide uses the same style, fonts and colors, so the set reads as one.
Grounded claims
Figures that cannot be found on your website are flagged before you render.

Carousel Maker FAQ
How many slides can a carousel have?
Usually 4 to 8 work best. The writer picks a number that fits the idea, and you can add or remove slides.
Can I make a LinkedIn carousel?
Yes. Every carousel render includes a PDF, which LinkedIn shows as a swipeable document post.
Is the carousel maker free?
OpenPromo is open source and free to self-host. Writing a carousel uses one AI call on your own YepAPI key, about $0.02 to $0.08. Rendering costs nothing unless you add AI pictures.
