The short answer
A LinkedIn document post is a post with a file attached, usually a PDF, that readers page through inside the feed. Because each page reads like a slide, people often call it a LinkedIn carousel or document carousel.
LinkedIn’s Help Center says you can upload documents to a post from your homepage, a Group or a LinkedIn Page, and suggests topics “such as career advice, culture stories, insights & trends, event content, and knowledge sharing.” Anyone who can see the post can download the document as a PDF.
Limits on the file
From LinkedIn’s Help Center pages on documents and supported media:
| Limit | What LinkedIn says |
|---|---|
| File types | PDF, PPT, PPTX, DOC and DOCX, on desktop, iOS and Android |
| File size | Up to 100 MB |
| Pages | Up to 300 |
| Words | Up to one million |
| Documents per post | One |
| Title | Required: an upload without one fails |
| After posting | The title and description can be edited; the document itself can’t be changed |
How it performs
Document posts are the strongest format on LinkedIn in Buffer’s 2026 engagement report, which calls them carousels: “it’s carousels (document/PDF posts) that earn the most engagement on LinkedIn.” Its medians by format:
| Format | Median engagement rate |
|---|---|
| Carousel (document or PDF) | 21.77% |
| Video | 7.35% |
| Image | 6.52% |
| Link | 3.81% |
| Text | 3.18% |
How to post one
On desktop: choose Start a post on your homepage, open More, and pick the Add a document icon. Choose the file from your computer, or from Dropbox or Google Drive, add a title and choose Done, then write the post’s description, with hashtags or mentions if you like, and post it.
LinkedIn requires a title, and its troubleshooting list names a missing title alongside file type, size and page count as reasons an upload fails. The title and description can be edited later, but the file can’t be swapped, so check every page before you share it: fixing a typo in the document means deleting the post and posting again.
Making one people page through
Buffer’s report also found a wide spread inside the format, with stronger carousels above 41% and weaker ones near 5.4%. The difference is mostly in the making:
- Put the whole promise on page one: it is the only page most people see before deciding to swipe.
- One idea per page, in type large enough to read on a phone.
- Make it a PDF, which works the same everywhere, and keep it as short as the idea needs.
- End on a page that says what to do next: follow, comment, or read the full piece.
- Write the post text as its own hook; it sits above the document in the feed.
Document posts and PostEase
PostEase publishes text, image and video posts to a LinkedIn personal profile on schedule, including several images in one post. It does not publish document posts yet; upload those in LinkedIn. YouTube, X, LinkedIn (personal profile), Pinterest, Bluesky, and WordPress publishing are live today; Instagram, TikTok, Facebook, and Threads are pending each platform's own API approval.
Questions
Is a LinkedIn carousel the same as a document post?
Yes, in everyday use. A carousel on LinkedIn is a document, usually a PDF, attached to a post and read page by page.
How many pages can a LinkedIn document have?
Up to 300 pages and 100 MB, in PDF, PPT, PPTX, DOC or DOCX.
Can I edit a LinkedIn document after posting?
You can edit the title and description, but not the document. To change the file, delete the post and create a new one.
Do document posts get more engagement on LinkedIn?
In Buffer’s 2026 report they earned a median 21.77% engagement, about three times video and images.
