Generate LinkedIn carousels in seconds
Document posts, also called carousels, are the single highest-engagement native format on LinkedIn in 2026 — averaging 6.6% engagement, roughly 3.7 times a standard text post, according to our 2026 benchmarks. They are also the format most people never make, because building one used to take an hour in Figma.
Why carousels win
LinkedIn rewards time-on-post. A good carousel keeps readers swiping for 15 to 20 seconds per post — compared to three or four seconds for a text update. The algorithm reads that dwell time as value and pushes the post further into feed. The engagement data follows.
The same dynamic explains why readers like them. A carousel is easier to consume than a wall of text and more substantive than a single quote image. You get a beginning, a middle, and an end — and the format encourages actually finishing the post before moving on.
How Postbrander builds carousels
You give Postbrander a topic or paste a longer article you want to adapt. The AI plans the carousel structure — a hook slide, body slides carrying one idea each, and a closer with a clear call to action. It then writes the copy for every slide in your voice profile, with headlines short enough to read at a glance and body text tuned to the slide width.
The layout engine places the text, applies brand-friendly typography, and exports a multi-page PDF that LinkedIn accepts as a document post. No Canva, no Figma, no manual slide-by-slide work.
Hook, content, close
The first slide is everything. LinkedIn shows readers the cover and the opening three lines of your caption in the feed — that is what earns the swipe. Postbrander writes the hook slide first, benchmarks it against patterns from our hooks that convert guide, and flags weak openers before you publish. For a deeper walkthrough of slide structure and cover design, see the carousel guide.
Middle slides carry one idea each. Closing slides include an explicit next action, which doubles the chance a reader comments, follows, or messages you.
Repurpose what you already have
Most carousels do not need new ideas — they need a format change. Paste a blog post, a long-form LinkedIn post that did well, or a section of a report, and Postbrander will adapt it into a 6 to 10 slide carousel in under a minute. One piece of source material can become a text post, a carousel, and a short-form video (see the LinkedIn video guide for how to handle that last one) — three posts from one piece of thinking.
Review before you publish
You get a live preview of every slide before the post goes out. Edit copy, reorder slides, replace the cover image, tweak the caption. Nothing publishes without your approval. If a carousel is not working, regenerate it against a different angle and try again — each regeneration costs one AI credit.

Frequently asked questions
How many slides should a LinkedIn carousel have?+
Six to ten slides is the tested sweet spot. Fewer than six and you lose the depth that earns the dwell time. More than twelve and drop-off kicks in hard. Postbrander generates carousels inside this range by default.
What file format do carousels publish in?+
Postbrander exports a multi-page PDF, which LinkedIn accepts as a document post. No Canva or Figma step — the layout, typography, and cover are handled automatically.
Can I edit carousel slides before publishing?+
Yes. You get a live preview of every slide, and you can edit copy, reorder slides, replace the cover image, or tweak the caption. Nothing publishes without your approval. You can also regenerate against a different angle if the first pass is not right.
Which plans include carousel generation?+
Carousels are included on Pro and Business plans. The free plan covers text posts and polls. Every paid plan counts a generated carousel as a single AI generation against your monthly allowance.
