How to Post a LinkedIn Carousel in 2026: Size, PDF and Steps

To post a LinkedIn carousel, save your slides as a PDF, start a post, click More, then Add a document. Upload the file, give it a title and press Post. Each page becomes a swipeable slide. LinkedIn accepts files up to 100 MB and 300 pages, and most carousels use square (1080 x 1080) or portrait (1080 x 1350) slides.

If you've been looking for a "carousel" button on LinkedIn, there isn't one. Here's how it really works, what size to use, and what the numbers say. We make VoiceMoat, which can turn your own images into a carousel, and we cover that near the end.

What a LinkedIn carousel actually is

LinkedIn removed native image carousels from normal posts in late 2023. Carousel ads still exist, but those are a paid product. What people call a carousel today is a document post: one file, shown a page at a time, that people swipe through.

Uploading several images doesn't give you this. They appear as an image grid. To get swiping, your slides have to be pages in one document.

How to post a carousel, step by step

These are the steps from LinkedIn's own help page.

On desktop:

1. Click Start a post on your homepage.

2. Click More, then the Add a document icon.

3. Choose your file from your computer, Dropbox or Google Drive.

4. Add a title and confirm. This title appears above the slides.

5. Write your post text. Hashtags and mentions are optional.

6. Click Post.

On mobile:

1. Tap Post.

2. Tap More, then Document.

3. Choose your file.

4. Add a title and tap Next.

5. Write your post text and tap Post.

LinkedIn's limits: PDF, PPT, PPTX, DOC or DOCX, up to 100 MB and 300 pages. Use a PDF, because it keeps your fonts and layout exactly as you made them.

Two things to know before you press Post. You can edit the post text afterwards, but you can't edit the document, so a typo on slide 4 means deleting the post and starting again. And anyone viewing it can download it as a PDF, so leave out anything you wouldn't hand to a stranger.

What size to make your slides

LinkedIn accepts a wide range of page shapes. These two are the common choices:

Whichever you pick, make every page the same size. Our LinkedIn image size guide has the sizes for every other format, checked on LinkedIn Help.

Do carousels really get more engagement?

It depends whose data you read.

Two studies put carousels first and one puts them second, with engagement figures that differ hugely. Part of the reason is that studies measure different things. Buffer notes that clicking through a carousel counts as an engagement on LinkedIn, so a format people tap through will score well almost by design. Buffer's own range is wide as well: strong carousels pass 41% and weak ones sit around 5.4%.

So carousels are worth trying, but compare them against your own posts instead of trusting one number.

How to make slides people finish

• Use the first slide as your hook. It's the only one most people see before deciding.

• One idea per slide. If it needs a paragraph, it needs two slides.

• Make the text large. Check it on your phone, not your monitor.

• Give people a reason to swipe. A numbered list or a before and after pulls them forward.

• End by asking for something: a comment, a follow, or a question to answer.

• Keep the post text short. Say why it's worth opening, and let the slides do the rest.

Our 30 slide-by-slide templates give you structures to start from, and the free carousel generator exports a PDF with no sign-up. For the post around it, see how to write a LinkedIn post.

Common mistakes

• Uploading images and expecting swipes. You'll get a grid.

• Different page sizes in one file. The slides jump around as people swipe.

• Tiny text. It may look fine on a laptop and be unreadable on a phone.

• Skipping the title. It's the label people see above your slides.

• Posting a sales deck. A carousel that only talks about you rarely gets past slide two.

Posting a carousel from your own images in VoiceMoat

VoiceMoat is an AI social media tool for LinkedIn and Twitter. If you already have the images, it saves you the PDF step:

1. In Studio, attach 2 or more JPEG or PNG images to a LinkedIn post. With 3 or more it starts on Swipeable carousel, and you can switch to Image grid.

2. Choose Square or Portrait 4:5, drag the slides into order, and turn page numbers on if you want them.

3. Slides that don't fit the shape get a plain border, so nothing is cropped.

4. Name the carousel. VoiceMoat fills in your post's first line to start, up to 100 characters, and sends it as LinkedIn's document title.

5. Post now or schedule it.

You can use up to 20 slides and 25 MB of images. Video can't go in a carousel. If you'd rather not make the images yourself, Media Studio can create carousel slides for you.

What each plan includes

To be clear, posting media starts on Pro. If you want to try it first, the $5 trial includes it, and you can see the plans here. If you only post a carousel now and then, LinkedIn's own uploader is free and works fine.
