A LinkedIn carousel is a multi-page PDF uploaded as a document post. LinkedIn converts each page to an image and renders the set as swipeable slides in the feed. This guide covers the six steps: plan, design, export, upload, caption, and schedule.
The format works because of how the LinkedIn feed measures attention. LinkedIn’s own engineering team built dwell time into feed ranking. Dwell time starts counting when at least half of a post is visible on screen. A carousel holds that state far longer than a single image.
One detail catches most people out. LinkedIn removed its native swipeable carousel in mid-2023, so every organic carousel on LinkedIn today is a document post built from a PDF file.
What You Need Before You Start
The prerequisite most people skip is the written slide outline. Deciding what goes on each slide before you open a design tool is what keeps a carousel to one idea per slide.
-
A design tool that exports multi-page PDFs (Canva’s free plan covers everything in this guide)
-
A LinkedIn personal profile or company page you can post from
-
A written topic and a rough slide-by-slide outline
-
Time: plan for a couple of hours on your first deck, nearly all of it design. Creators on r/LinkedInTips consistently describe carousel design as the step that takes hours.
-
A social media scheduler, if you want the carousel to publish at a set time without opening LinkedIn manually
No paid design subscription is required for any step here.
LinkedIn publishes hard limits for document posts, and every carousel inherits them:
| Requirement | Value |
|---|---|
| Accepted file types | PDF, PPT, PPTX, DOC, DOCX |
| Recommended file type | |
| Maximum file size | 100 MB |
| Maximum pages | 300 |
| Documents per post | 1 |
| Document title | Required at upload |
| Page sizing | Every page must be the same size |
| Layers | Must be flattened or merged |
| Animation and video | Not supported, rendered as static images |
| Editing after posting | Title and description only, never the file |
| Recommended slide size | 1080 x 1350 px portrait (4:5), or 1080 x 1080 px square |
| Safe margin | 50 px on all four edges |
| Color mode | sRGB |
The first ten rows are LinkedIn’s documented requirements. The last three are design conventions rather than platform rules, and they exist to survive LinkedIn’s image compression.
Step 1. Plan Your Carousel Topic and Slide Structure
Start with one focused topic, assign each slide one idea, and map out 8 to 12 slides before you open your design tool.
The carousel format rewards focus. A deck spread across five different topics gives viewers a reason to stop swiping early. Pick one question, one process, or one insight, and build the entire deck around it.
Five carousel formats consistently earn swipes on LinkedIn:
-
Step-by-step guide: one step per slide
-
Listicle: one item per slide
-
Data story: one statistic or one chart per slide
-
Case study: problem, action, and result, in that order
-
Myth versus reality: one misconception corrected per slide
Pull a subject from this list of LinkedIn post ideas if nothing obvious comes to mind.
A working slide structure:
-
Cover slide: your hook statement or question
-
Slides 2 to 4: the problem or context
-
Slides 5 to 9: the core content (steps, data, or insights)
-
Slides 10 to 11: the key takeaway
-
Final slide: one clear call to action
Aim for 8 to 12 slides as a starting point. Simple how-to content can run 5 to 7 slides, and data-heavy frameworks can run to 15. Keep each slide to one idea, under 40 words across the headline and body text combined.
Done: You have a written slide plan with a title or idea assigned to each slide.
Step 2. Design Your Slides in Canva
Set your Canva canvas to 1080 by 1350 pixels and design one slide per page. Keep all text and visuals inside a 50-pixel safe margin on every edge.
Create a new Canva design at 1080 x 1350 pixels. This is the portrait 4:5 ratio that fills the most mobile screen space in the LinkedIn feed, which keeps viewers swiping longer. A 1080 x 1080 pixel square also works if your design requires it.
Design rules that matter for LinkedIn:
-
Leave a 50-pixel margin on all four edges. LinkedIn crops the outer areas during rendering on some devices.
-
Keep text at 20 points or larger. Smaller text is difficult to read on mobile.
-
Use sRGB color mode, not CMYK. LinkedIn converts PDFs to images during processing, and CMYK colors shift in that conversion.
-
One page in Canva equals one slide in LinkedIn. Add every slide as a separate page in the same Canva document.
PostMonk tip: PostMonk Pro and Agency plans include a direct Canva integration. You can pull any Canva design into the PostMonk composer and publish or schedule it without downloading and re-uploading the file.
Done: You have a multi-page Canva document with one design per page, all sized at 1080 x 1350 pixels.
Step 3. Export Your Slides as a Multi-Page PDF
In Canva, click Share, select Download, choose PDF Print as the file type, confirm all pages are selected, and download.
In Canva:
-
Click “Share” in the top right corner.
-
Select “Download.”
-
Under “File type,” choose “PDF Print” (this exports at higher quality than PDF Standard).
-
Confirm “All pages” is selected.
-
Click “Download.”
Canva exports the entire document as one multi-page PDF. That single file is what you upload to LinkedIn, and each page in it becomes one swipeable slide.
LinkedIn’s document upload requirements name three file conditions that quietly break carousels. Every page must be the same size, layers must be flattened or merged, and any animation or video renders as a static image. Canva’s PDF Print export satisfies all three for a standard multi-page design.
LinkedIn also compresses every PDF it processes. Starting at 1080 x 1350 pixels with PDF Print quality leaves enough resolution headroom that the compressed output stays sharp. A well-designed 12-slide carousel typically comes out under 10 MB, against a 100 MB limit.
Done: You have a single multi-page PDF saved to your device, under 100 MB, with uniform page sizes and flattened layers.
Step 4. Upload the PDF to LinkedIn as a Document Post
Open the LinkedIn post composer, add a document, upload your PDF, give it a document title, write your caption, and post.
Proofread the deck before you upload it. Per LinkedIn’s document upload FAQ, you can edit a published document post’s title and description, but never the file itself. Fixing a typo on slide 4 means deleting the post and republishing it, which resets every like, comment, and impression.
On desktop at LinkedIn.com:
-
Click “Start a post.”
-
Click “More,” then select the document icon.
-
Click “Choose file,” or import the PDF from Dropbox or Google Drive.
-
Select your PDF.
-
Enter a document title and click “Done.” The title is required, and it is separate from your caption.
-
Write your caption (see Step 5).
-
Click “Post.”
On the LinkedIn mobile app:
-
Tap “Post.”
-
Tap the “More” icon, then tap “Document.”
-
Select the PDF from your device or a connected cloud service.
-
Add a document title and tap “Next.”
-
Write your caption.
-
Tap “Post.”
Each post carries one document only, so a carousel cannot be split across two files.
Using PostMonk:
Open any PostMonk workspace, create a new post, select your LinkedIn account, and attach the PDF. PostMonk submits it to LinkedIn as a document post, which renders as a carousel in the feed. You can schedule it for an exact time or drop it into your posting queue.
Done: Your LinkedIn post is created with the PDF attached, proofread, and a document title set.
Step 5. Write Your LinkedIn Post Caption
Open the caption with one specific hook in the first line. Explain what the carousel delivers in 2 to 3 lines, then prompt the reader to swipe.
The caption is the gatekeeper. LinkedIn shows only the first 2 to 3 lines before a see-more break, so the opening line decides whether anyone swipes at all.
Treat the first line like a subject line. A specific claim beats a generic opener. Naming a number and a mistake, such as three things creators get wrong about carousels, earns more opens than announcing a new post.
A caption structure that works:
-
Hook (1 line): a specific claim, question, or tension
-
Context (1 to 2 lines): why this matters to your reader
-
Invitation (1 line): tell them to swipe, or state what they will learn
Place 3 to 5 hashtags at the end, not in the opening lines. Front-loaded hashtags cost you hook space.
For timing, publish when your own audience is active. The best time to post on LinkedIn guide covers the day-and-hour patterns in detail.
Using PostMonk’s caption composer: PostMonk’s AI tools generate caption drafts from a topic or prompt. You can apply your tone, edit inline, and use first-comment scheduling to include a link or secondary message without cluttering the main caption.
Done: You have a caption with a clear, specific hook in the first line.
Step 6. Schedule and Publish Your Carousel
Schedule your carousel for the time your LinkedIn audience is most active, and use a queue if you post on a regular cadence.
LinkedIn’s native scheduler handles PDF carousels. LinkedIn’s scheduling documentation puts the window at one hour from now to three months ahead. It takes one post at a time for one account, with no bulk scheduling, team approval, or queue features.
For a recurring content schedule, a multi-account workflow, or team approval, a dedicated scheduler removes the manual overhead. PostMonk supports queue-based and exact-time scheduling for LinkedIn PDF carousels on all plans, including Starter, Pro, and Agency. Set your time, pick your LinkedIn account, and attach the PDF.
Scheduling matters more for carousels than for any other format. LinkedIn’s engineering team explained why in Understanding dwell time to improve LinkedIn feed ranking, published in May 2020.
Clicks, wrote engineer Siddharth Dangi, are “noisy indicators of engagement” that miss how long a member stayed. Dwell time is LinkedIn’s fix, measured from the moment at least half of a post is visible. A carousel is built for exactly that metric.
Every swipe keeps the post on screen for a few more seconds, so a 10-slide deck accumulates dwell time a static image cannot match. Publishing when your audience is actually scrolling is what turns that mechanic into distribution.
See PostMonk’s LinkedIn scheduling features for the full feature set, or How to schedule LinkedIn posts for the wider workflow. For other networks, see How to schedule Instagram posts and How to schedule TikTok posts.
Done: Your carousel is scheduled, and every swipe it earns feeds the dwell-time signal LinkedIn uses to decide how far to distribute it.
Common Mistakes to Avoid
The costliest mistake is uploading before proofreading, because LinkedIn never lets you replace the file afterwards. These five failures account for most carousels that underperform.
Mistake 1: Designing at the wrong size or ignoring the safe margin
Presentation dimensions such as 1920 x 1080 pixels produce blurry carousels. LinkedIn converts PDF pages to images and compresses them, so an undersized slide loses quality. Text placed near the slide edges also gets cropped on some devices.
Design at 1080 x 1350 pixels (portrait) or 1080 x 1080 pixels (square). Keep all critical text and branding 50 pixels clear of every edge.
Mistake 2: Uploading individual images instead of a PDF
LinkedIn’s multi-image post renders as a gallery, not a full-screen swipeable carousel, and it is a different product from the document post. Upload a single multi-page PDF using the document option in the composer. A document post also carries up to 300 pages, far more than any image post allows.
Mistake 3: Including hyperlinks inside your PDF slides
LinkedIn converts each page of your PDF into a compressed image, so hyperlinks embedded in the file are not clickable in the published carousel. Do not place “click here” calls to action pointing at URLs inside the slides. Put every link in the post caption or in a scheduled first comment.
Mistake 4: Uploading before proofreading
LinkedIn lets you edit a published document post’s title and description, but never the uploaded file. A typo on slide 6 cannot be patched. The only fix is deleting the post and republishing, which wipes the engagement it already earned.
Read the exported PDF end to end before it goes near the composer.
Mistake 5: Writing a weak opening line in the caption
LinkedIn shows only 2 to 3 lines of caption before it truncates with a see-more break. A vague first line loses the reader before slide one. Write that first line the way you would write an email subject line, specific and immediate rather than generic.
FAQs
What is a LinkedIn carousel post?
A LinkedIn carousel post is a document post created by uploading a multi-page PDF. LinkedIn converts each PDF page to an image and renders them as swipeable slides in the feed. LinkedIn removed its native multi-image carousel in mid-2023, so the PDF document post is the only organic carousel method in 2026.
Can you still post carousels on LinkedIn?
Yes. The PDF document post is the current carousel format on LinkedIn. Upload a multi-page PDF using the document option in the post composer, and LinkedIn renders each page as a swipeable slide. The feature works on personal profiles and company pages alike.
What size should a LinkedIn carousel be?
Design your slides at 1080 x 1350 pixels, the portrait 4:5 ratio. That format fills more of the mobile screen than a square, where most LinkedIn scrolling happens. A 1080 x 1080 pixel square is also fully supported. Keep a 50-pixel safe margin on all four edges and export in sRGB.
How many slides should a LinkedIn carousel have?
Aim for 8 to 12 slides as a starting point. Simple how-to content works well at 5 to 7 slides, and data-rich decks can run to 15. LinkedIn caps document posts at 300 pages, so the real constraint is attention rather than the platform. Let your content set the count.
How long does it take to make a LinkedIn carousel?
Plan for a couple of hours on your first carousel, and far less once you have a reusable template. Design absorbs nearly all of it. Creators on r/LinkedInTips describe carousel design as the step that reliably takes hours. Export, upload, and caption writing together take about 15 minutes.
Can you edit a LinkedIn carousel after posting?
No. LinkedIn lets you edit a published document post’s title and description, but not the uploaded file. Correcting a slide means deleting the post and publishing the corrected PDF again. That loses the likes, comments, and impressions the original earned, so proofread before uploading.
Can I schedule a LinkedIn carousel post?
Yes. LinkedIn’s native scheduler handles PDF carousels from one hour ahead to three months ahead, one post at a time. For queue scheduling, multi-account workflows, or team approval, a third-party tool carries more volume. PostMonk supports queue and exact-time scheduling for LinkedIn PDF carousels on Starter, Pro, and Agency plans.
Do clickable links work inside a LinkedIn carousel PDF?
No. LinkedIn converts each PDF page into a compressed image, so any hyperlink embedded in the file stops being clickable in the published carousel. Put links and calls to action in the post caption, or in a first comment scheduled alongside the post. Keep the slides for visual content.
What file format should I use for a LinkedIn carousel?
PDF is the best choice. LinkedIn accepts PDF, PPT, PPTX, DOC, and DOCX for document posts, but PDF gives you the most control over layout, fonts, and image quality. Export from Canva using “PDF Print,” keep the file under 100 MB, and make every page the same size.
What is a LinkedIn carousel ad?
A LinkedIn carousel ad is a paid format built in LinkedIn Campaign Manager. It uses individual image cards rather than a multi-page PDF, supports up to 10 cards, and sends clicks to an external URL from each card. Carousel ads carry a sponsored label and need an ad budget, so they are a separate product from the organic document post.
