LinkedIn Carousel PDF: How to Post a Carousel on LinkedIn

A LinkedIn carousel PDF is a multi-page PDF added to a LinkedIn post as a document, which LinkedIn displays page by page so readers move through it like slides. To post one, design pages of one size, export them as a single PDF, start a post, add the file as a document, then write the post text and publish.

• LinkedIn Marketing Solutions' document ads specification accepts 5 file types: PDF, DOC, DOCX, PPT and PPTX.
• LinkedIn's document ads guide sets a 100 MB file limit and a ceiling of 300 pages or 1 million words, and recommends keeping documents under 10 pages.
• The same specification lists 10 standard PDF page layouts, from Letter (8.5 by 11 inches) to A4 and B5, and asks for pages of different sizes to be fitted to one size.
• Pew Research Center's social media fact sheet (20 November 2025) gives 32% as the share of US adults using LinkedIn, from its 2024 survey.

How do you post a PDF carousel on LinkedIn, step by step?

Make the pages, save them as one PDF, then add that file to a new post as a document rather than as photos. LinkedIn turns the pages into a document viewer that readers move through one page at a time.

1. Design every page at the same size, with one idea per page and text large enough to read on a phone.
2. Export the pages as a single PDF, flatten any layers, and open the file on your own phone to check it.
3. On LinkedIn, start a post and choose the option to add a document, which sits among the extra options beside photo and video.
4. Upload the PDF and, where LinkedIn asks for a document title, write one a reader would understand rather than the file name.
5. Write the post text with the promise, a short summary and your website address, then post it.

The menu labels and icons in step 3 move between app versions, so if you cannot see the document option, look under the button that shows more post types, or check the LinkedIn Help Center for the current route. Posting from a computer is usually easier for a first attempt, because the file is already where you designed it. After posting, open the post on a phone straight away and move through every page, since that is how most people will meet it.

The difference from Instagram matters. Many people know carousel posts as a set of photos, but on LinkedIn the swipe-through effect comes from a document, so you are designing the pages of a short booklet rather than a stack of pictures. That changes how you plan the cover, how you place text and how you check the file before you publish.

What size and shape should the PDF pages be?

Pick one page size and keep every page to it. LinkedIn's document ads specification accepts vertical, horizontal or square pages and lists standard layouts such as A4 and Letter.

The specification is written for document ads, but it is the clearest public statement LinkedIn makes about document files, and its technical rules are sensible for ordinary posts too. It asks for multi-layer PDFs to be flattened or merged and for pages of different sizes to be fitted to one size. Following both rules before you upload is quicker than fixing an untidy post once your contacts have seen it. Check the LinkedIn Help Center for the current limits on ordinary document posts, because they can differ from ad limits and change without notice.

Shape is a choice between reading comfort and space. A square or portrait page fills more of a phone screen than a landscape one, while a landscape page suits charts or wide comparisons viewed on a computer. Whatever you choose, design the pages at the size you will export, rather than resizing at the end, so that text stays sharp.

How many pages should a LinkedIn carousel have?

Enough to finish one idea, and LinkedIn's own advice for document ads is to stay under 10 pages. The 300 page ceiling is a technical limit, not a target.

A useful pattern is a cover, one page per point and a closing page. A guide with six points therefore needs eight pages, which sits inside LinkedIn's recommendation with room to spare. If your outline runs past ten, split it into two documents posted a week apart, each with its own cover promise, rather than asking a busy reader to keep going.

There is no published figure for the ideal length of an ordinary document post. The method is to post a few documents of different lengths on similar topics and compare reactions, comments and reposts against impressions in each post's analytics. Keep notes on what you changed, because over a handful of posts that record will tell you more than any general rule.

What should go on the first and last pages?

The first page should promise one specific result, and the last page should tell the reader one thing to do next. Everything between them delivers the promise.

The cover is the only page most people see before they decide whether to read on. Write the promise in a few words, such as "6 checks before you sign a commercial lease" for a hypothetical solicitor in Birmingham, and keep the design simple enough that the promise is the first thing the eye lands on. Put your business name small on the cover, not large, because the reader cares about the result before they care about who is offering it.

The closing page should name one action, such as booking a call, downloading a price list from your website or sending a message. Put your website address there in plain text, and repeat it in the post text, where every reader can see it. LinkedIn's document ads specification asks for any hyperlinks in a document to be secure, but do not rely on a link inside the PDF as the only way to reach you.

Which mistakes stop a LinkedIn carousel working?

Small text, crowded pages and text that exists only inside images cause most problems. Each one is easy to fix before you upload.

Mistake	Why it hurts	Fix
Text sized for a printed page	Unreadable on a phone screen	Fewer words, larger type, check on a phone
Several points per page	Readers skim and miss the point	One idea per page
Mixed page sizes or layers	Breaks LinkedIn's own file rules	One page size, flattened PDF
Key points only on the pages	Readers who never open the document get nothing	Summarise the points in the post text
File name as the title	Looks unfinished in the feed	A clear, human title

The last two mistakes are about people who do not open the document. The W3C Web Accessibility Initiative's tutorial on images of text notes that images of text are more likely to distort and pixelate when resized, and that a text alternative should contain the same text shown in the image. A short summary of the points in the post text does a similar job for a LinkedIn document, helping readers who use screen readers, readers on poor connections and anyone deciding from the feed whether to open it.

Questions business owners ask about LinkedIn carousels

Can I post a PowerPoint file instead of a PDF?

LinkedIn's document ads specification accepts PPT and PPTX as well as PDF. Exporting to PDF yourself is still the safer route, because it fixes your fonts and layout before LinkedIn processes the file. Check the result on a phone either way.

Can I reuse my Instagram carousel on LinkedIn?

Yes, if the slides share one size and the text is large. Export the same slides as a single PDF, add a cover promise suited to LinkedIn readers, and rewrite the post text for the network. Remove anything that only makes sense on Instagram, such as a prompt to tap a link in your profile.

Should the post text repeat what is in the PDF?

It should summarise it, not copy it. Give the promise, the main points in a sentence or two and the action you want, so the post makes sense to someone who never opens the document. Readers then open the document for the detail.

How do I know whether a LinkedIn carousel worked?

Look at the post's analytics a week after posting. Compare reactions, comments, reposts and visits to your website against the number of impressions, and set those rates beside your other posts rather than judging the document on its own.

Turn your next tips list into a LinkedIn PDF this week

Pick one list your customers already ask about, such as steps, checks or common mistakes, and outline it as a cover, one page per point and a closing page.

Design it at one size, export it as a single PDF and check every page on your phone before you post. Write post text that summarises the points and names the action, then compare its numbers with your usual posts after a week. If it does better on the rates that matter to you, plan the next document from another question customers ask.

To skip the design work, type your website into the AI Social Media Post Generator to see three posts with captions for your business. Its tips carousel format lays out the slides with your own photos and the website's, a second check compares every claim with your website, and it saves the carousel as a PDF for LinkedIn. On a computer, LinkedIn opens with the post words already in and the files download ready to add, and a finished post with its pictures and captions costs 1 credit (about $0.65).
