How to Post a Carousel on LinkedIn (The PDF Method)
You have a great idea for a B2B post. You know that swipeable carousels get the highest engagement on the platform. But when you try to upload your images, LinkedIn displays them as an ugly grid instead of a sleek slider.
Posting a carousel on LinkedIn requires a specific, often misunderstood mechanical step. This guide shows you exactly how to get that seamless, swipeable format.
The Secret: Why It Must Be a PDF Document
Unlike Instagram, where you upload multiple separate images, LinkedIn’s carousel feature is actually its Document Reader.
When you upload a document to LinkedIn, the platform automatically renders each page of that document as a swipeable slide in the feed. Therefore, to post a carousel, you must export your design as a single PDF file, not a folder full of PNGs or JPGs.
Step-by-Step Guide to Uploading Your Carousel
Once you understand the PDF rule, the actual upload process is simple.
1. Export Your Design as a PDF
Whether you designed your carousel manually or used an automated generator, ensure you export the final file as a Standard PDF. Do not use interactive PDFs or excessively large print-quality files, as they may fail to process on LinkedIn.
2. Click "Add a Document" on LinkedIn
Go to your LinkedIn homepage and click "Start a post." Do not click the photo or video icon. Instead, look for the icon that looks like a sheet of paper with a folded corner (the "Add a document" button). If you don't see it immediately, click the "More" (three dots) button to reveal it.
3. Add a Title and Description
Select your PDF file. LinkedIn will prompt you to enter a Document Title. This title is visible to users who download the file, so make it professional. Click "Done," add your post caption and hashtags, and hit "Post."
Troubleshooting: Why Isn't My Carousel Working?
If your upload doesn't look right, you likely made one of two common errors.
1. Uploading Images Instead of PDF
If your post looks like a collage or a grid rather than a swipeable deck, you selected multiple image files instead of a single PDF. Delete the post, convert your images into one PDF, and try again.
2. File Size Too Large
If the document fails to upload or process, it might be too large. While LinkedIn allows up to 100MB, enormous files can time out or display slowly for users on mobile networks. Compress your PDF before uploading.
