LinkedIn carousel PDF maker from your slide images
LinkedIn turns a PDF into a swipeable carousel, but only a PDF, and only one whose pages are all the same size. Drop in your slides, put them in order and download that PDF. Runs in your browser; your images never leave your device.
How to make a LinkedIn carousel from images
Drop in your slide images
JPEG, PNG or WebP, as many as the deck needs. They are read in your browser and never uploaded.
Put them in order
Slide 1 comes first on LinkedIn and sets the page size for the whole document. Move or remove slides until the order is right.
Decide how odd-shaped slides fit, if asked
When every slide has the same shape there is nothing to decide. If one differs, you choose between fitting it inside the page with bands, or cropping it to fill.
Download the PDF
One file, one page per slide, every page the same size.
Post it on LinkedIn as a document
Start a post, choose to add a document, upload the PDF and give it a title. LinkedIn shows it as a carousel people swipe through.
LinkedIn document limits
From LinkedIn's own help pages on sharing documents. A carousel of image slides is far inside both limits; the one that catches people out is the rule about page sizes.
| File types LinkedIn accepts for a document | PDF, PPT, PPTX, DOC, DOCX |
|---|---|
| Largest file | 100 MB |
| Most pages | 300 |
| Page sizes | All the same; mixed sizes must be fitted to one |
| Page size this tool uses | Slide 1's shape, at most 1080 pixels wide |
Why a PDF and not several images
A LinkedIn post with several images shows the first one large and squeezes the rest into small cropped thumbnails. A document shows every page full size, one at a time, with arrows to swipe through, which is what people mean by a LinkedIn carousel.
Slides from one panorama
To cut one wide image into slides that line up edge to edge, use the carousel splitter, which can also save the result straight to a LinkedIn PDF.
Posting these every week?

OpenCommon questions
How do I post a carousel on LinkedIn?
Upload it as a document. Start a post, choose to add a document, pick the PDF and give it a title. LinkedIn shows each page full size with arrows to swipe through. A post with several images instead shows the first large and the rest as small cropped thumbnails.
Why does LinkedIn need every page the same size?
LinkedIn's own guidance for documents says pages of different sizes must be fitted to one size, and a carousel that jumps between shapes as you swipe looks broken. This tool uses slide 1's shape for every page and only asks you how to fit the others when one actually differs.
What size should LinkedIn carousel slides be?
Any shape works as long as every slide has the same one. Portrait 4:5 at 1080 × 1350 takes the most room in the feed; square 1080 × 1080 is the other common choice. Pages here are made at the first slide's shape, at most 1080 pixels wide.
How many pages can a LinkedIn document have?
Up to 300 pages and 100 MB, according to LinkedIn's help pages. A carousel of image slides stays far inside both; this tool refuses a PDF that would break either limit rather than letting LinkedIn reject it.
Are my images uploaded anywhere?
No. The images are read, drawn and assembled into the PDF in your browser. Nothing is sent to a server.
Is there a watermark or a limit?
No watermark, no signup and no limit on how many PDFs you make.
