How to Create a LinkedIn Carousel PDF (Step by Step)

A LinkedIn carousel is usually a multi-page document that readers can move through in the feed. You can create one as a PDF and upload it as a document post. LinkedIn supports PDF document uploads and recommends PDF for upload quality.

This guide shows how to plan the slides, build the PDF, publish it, and check whether it helped your audience. You do not need a paid tool to publish a document on LinkedIn.

Start with one useful idea#

Choose a topic that benefits from steps, examples, or a visual comparison. A 7-slide document about one problem is easier to follow than 20 slides covering your whole industry.

Example topic: Three mistakes teams make when they introduce a CRM. The audience is owners of small B2B companies. The promised outcome is a checklist they can use before their next rollout.

A simple outline:

1. Cover: “3 CRM rollout mistakes small B2B teams can avoid.”
2. Context: why adoption often fails after the software is purchased.
3. Mistake 1: importing messy contact data; add a practical fix.
4. Mistake 2: skipping a clear owner; add a practical fix.
5. Mistake 3: measuring activity instead of useful outcomes; add a practical fix.
6. Checklist: three questions to ask before launch.
7. Closing: invite a specific discussion, such as “Which step caused the most friction for your team?”

Use only examples you can stand behind. If you add a statistic, link to its original source in the post or on the slide. Don't let an AI tool invent a client result.

Design slides people can read#

Write one main point per slide. Use a short heading, a few lines of body text, and a clear visual hierarchy. Keep type large enough to read on a phone. Check every slide at mobile size before exporting.

Use the same page size throughout the document. Give the cover a descriptive title instead of a vague teaser. Add your name or brand only where it helps readers identify the source; it should not compete with the message.

Export a PDF and review it page by page. LinkedIn's document guidance says PDFs can be downloaded by people who can view the post; it also notes that animations display as static images. LinkedIn currently lists a 100 MB and 300-page maximum for document uploads, but a practical carousel should normally be much shorter. LinkedIn says you cannot replace the document in a post after upload, so check spelling and page order first.

Publish the PDF directly on LinkedIn#

LinkedIn's upload instructions describe this flow for desktop:

1. Choose Start a post.
2. Open More, then Add a document.
3. Select the PDF and add a clear document title.
4. Write a post description that tells readers what they will learn.
5. Review the preview and publish.

Your caption should add context, not repeat every slide. For the CRM example: “Buying a CRM was the easy part. Getting the team to use it required three decisions we had skipped. Here is the checklist we now use before a rollout.” Add your own experience and one specific question at the end.

If you first need help drafting the caption, try the free LinkedIn post generator. It creates a draft from a topic and audience without signup; edit the result before publishing.

Create a carousel from a post in PostedIn#

If you already have a finished post, PostedIn can turn it into carousel slides. According to the current PostedIn carousel feature page, you can pick a template and format, add a logo, edit individual slides, render a PDF, and publish it as a LinkedIn document. The product describes 16 templates, four formats, and a 3–10 slide workflow. Check the in-app preview before publishing so your document reflects the latest version of your text.

This route is useful when you want a post and document to share the same idea without copying every sentence onto a slide. Keep the strongest examples in the PDF and use the post text to explain why the topic matters.

Check the result after publishing#

Record the post URL, publication date, topic and format. Look at the document post's impressions and engagement in LinkedIn post analytics. Read the comments as well: a small number of questions from the right audience can be more useful than a large impression count.

Compare several carousels on similar topics with your text posts over a few weeks. Format alone does not guarantee more reach. The goal is to learn whether your audience finds the document useful enough to read, save or discuss.

Common questions#

Is a LinkedIn carousel the same as a PDF document post?#

For this workflow, yes: the swipeable pages come from a multi-page PDF shared as a LinkedIn document. LinkedIn's own help calls it a document post.

Can I create a LinkedIn carousel for free?#

Yes. Create a PDF in a document or design tool, then upload it through LinkedIn's document option. The free PostedIn post generator can help draft the accompanying caption.

What size should the PDF be?#

Use a consistent page size and test readability on mobile. PostedIn offers several format choices, including portrait, square and landscape. The best choice depends on your content and layout; avoid treating one ratio as a guaranteed way to increase reach.

Can I edit a carousel after publishing?#

LinkedIn says you can edit the description or remove the post, but you cannot replace the uploaded document. Proofread the PDF before posting.
