How to Post a Carousel on LinkedIn With a PDF Document

The swipeable posts you see on LinkedIn are documents. Build the slides anywhere, export a PDF, and LinkedIn turns each page into a slide readers flick through.

Updated October 2026

How to post a carousel on LinkedIn: design your slides, export them as a PDF, then start a post, click the plus icon, choose Document, upload the file and give it a title. LinkedIn displays each page of the PDF as a slide readers swipe or click through, which is what everyone on LinkedIn calls a carousel.

There's no separate carousel button for ordinary posts. The document upload is the format, and it works from a personal profile or a company Page, on the desktop site or in the mobile app. The rest of this page covers sizes, what tends to work, and how to tag people in the post.

The part most guides skip

A LinkedIn carousel is a document post: a PDF, or a PowerPoint or Word file, uploaded to a post and shown as a set of pages the reader moves through one at a time. LinkedIn calls the feature documents; the people who use it call the result a carousel, because the experience is the same as swiping through slides.

As of October 2026, the post menu has no option labeled carousel for ordinary posts; LinkedIn's Help Center describes the document upload, under the plus icon in the post box, as the way to share slides. Guides that send you looking for a dedicated carousel button are describing something you won't find there. Carousel Ads do exist, but they're a paid format built in LinkedIn's Campaign Manager, not something you post from your profile.

Document posts suit LinkedIn's audience: step-by-step frameworks, short case studies, checklists and data that would be a wall of text as a normal post. They also show their numbers publicly, starting with the reaction count under the post, which is the figure LinkedIn likes add to. That count doesn't decide whether someone reads slide two; the first page does.

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

Build the slides first, in any tool that exports a PDF: PowerPoint, Keynote, Google Slides or Canva all do. Then, on the desktop site, following the steps in LinkedIn's Help Center as of October 2026:

  • Click Start a post at the top of your feed.
  • Click More, the plus icon at the bottom of the post box, then the Document icon.
  • Choose your file from your computer, or from Dropbox or Google Drive. LinkedIn accepts PDF, PPT, PPTX, DOC and DOCX.
  • Add a title for the document and click Done. The title is required, and readers see it above the slides.
  • Write the post text, where hashtags and @mentions go, and click Post.

Posting from a company Page

Switch to the Page's admin view first, then use the Page's own Start a post box. The steps are the same, and the post appears under the Page's name instead of yours.

Why PDF rather than PowerPoint

A PDF keeps your fonts and layout exactly as designed, where a PowerPoint file can come through with substituted fonts. LinkedIn's Help Center adds three PDF rules: every page must be the same size, layered PDFs have to be flattened first, and any video or animation shows as a static image.

Does LinkedIn still support carousels?

Yes, in the form of document posts, which are how people publish carousels as of October 2026. What you won't find is a separate carousel option for ordinary posts: LinkedIn's Help Center routes slide-style content through the Document icon.

Two things are easy to confuse with it. Uploading several images to a normal post creates a grid that opens into a gallery, not a set of pages that swipe one by one. And Carousel Ads, the paid format, are built in Campaign Manager and appear labeled as promoted. If your goal is an ordinary post that people swipe through, the document upload is the one to use.

LinkedIn doesn't force a page shape, but the shape decides how much of the feed the post takes up. These are the choices that work in practice:

  • Square, 1080 x 1080 pixels: safe everywhere, and the most common choice.
  • Portrait, 1080 x 1350 pixels: fills more of a phone screen, which is where most people scroll.
  • Landscape, 16:9: fine for slide decks you already have, but it takes the least space in the mobile feed.
  • Keep every page the same size. LinkedIn requires it for PDFs, and mixed sizes would jump as the reader swipes anyway.

File limits

As of October 2026, LinkedIn's Help Center sets document uploads at a maximum of 100 MB and 300 pages. A carousel rarely needs more than 10 to 15 pages, so the limits matter only for long reports.

Do PDF carousels get more reach?

Not because they're carousels. LinkedIn hasn't said it favors document posts as a format. What LinkedIn has described, on its engineering blog, is that time spent on a post counts as a signal, measured in the feed and again after someone clicks into a post or opens a document. A document people actually page through generates that signal; a document they skip doesn't.

So the format helps only when the slides earn the swipe. The first page has to work as a headline that makes someone want page two, and each page should carry one idea in large type. How the LinkedIn algorithm works covers dwell time and the other signals in more detail.

The practical test is the post's analytics: compare impressions with reactions and comments against your normal text posts over a few weeks, rather than judging from one upload.

How do you tag someone in a LinkedIn post?

Type the @ symbol in the post text, then start typing the person's or company's name, and pick them from the list that appears. The name turns into a link to their profile or Page. LinkedIn's document instructions confirm that @mentions work in the description of a document post, which is the text above the slides.

A few rules make tagging work:

  • You can mention people and company Pages; if a name doesn't come up, the member may have limited who can mention them.
  • Tags go in the post text, not inside the PDF. Names on the slides themselves aren't clickable.
  • Tag people who are actually part of the content, such as co-authors, a company you studied or a source. Mass-tagging people for reach tends to annoy them and reads as spam.
  • If the name list doesn't appear, keep typing more of the name, or check the spelling of how they appear on LinkedIn.

Can you post a carousel from a phone?

Yes. In the LinkedIn app, tap Post, then More, then Document, and pick the file from your phone or a cloud drive. Add the title, tap Next, write the text and post.

Building the slides on a phone is the harder part. Most people design on a computer, save the PDF to cloud storage and upload from the phone when it suits them. Whichever device you use, open the post on your phone afterwards to check the text on each page is readable at mobile size, since that's how most readers will see it.

If you'd rather prepare the post now and publish later, how to schedule a post on LinkedIn explains the built-in scheduler.

The same thing that makes any post worth reading, compressed into pages. A promise on page one, one idea per page after that, and a last page that tells the reader what to do next: comment with their view, follow for the next one, or visit a link in the comments.

Comments matter more than reactions on LinkedIn, because a comment carries the commenter's name and title and puts the post in front of their network. How to write engaging LinkedIn posts goes into what draws comments rather than a passing like.

The reaction count is still the first number a reader sees under the post. LinkedIn likes add to that count using only the public post link, never your login, and they don't change what LinkedIn shows to whom. Every LinkedIn service is on the LinkedIn page.

Questions people ask about LinkedIn carousels

What file do I need to post a carousel on LinkedIn?

A PDF is best, because it keeps fonts and layout intact. LinkedIn also accepts PowerPoint and Word files for document posts, and turns each page into a slide.

Is there a carousel button on LinkedIn?

Not for ordinary posts. You create a carousel by choosing the Document icon under More in the post box. Carousel Ads are a separate paid format in Campaign Manager.

What is the best size for LinkedIn carousel slides?

Square at 1080 x 1080 pixels is the safe default; portrait at 1080 x 1350 fills more of a phone screen. Keep every page the same size.

How many pages can a LinkedIn document post have?

As of October 2026, LinkedIn's Help Center sets a limit of 300 pages and 100 MB per document, but carousels work best at about 10 to 15 pages.

Can I tag people inside a LinkedIn carousel?

Only in the post text. Type @ and choose the person or Page from the list. Names written on the PDF pages aren't clickable and don't notify anyone.

Do LinkedIn carousels get more reach than text posts?

Not automatically. LinkedIn counts time spent on a post as a signal, so a carousel helps when people actually page through it, and does nothing extra when they don't.
