tl;dr: Upload a PDF document in which each slide of the carousel is one page.

I wanted to post a Carousel post in LinkedIn, but had to wade through a million pages of crap in Google from companies trying to sell shit. Here’s how to do it simply.

  1. Create your carousel slides. I like using Excalidraw. Here’s an example of two simple slides (that I’ll use for posting this article on LinkedIn ∞)

    1

  2. Export each slide as its own image file. In Excalidraw select the objects that you want to make up the slide and hit shift-cmd-E. Set it to Only selected, and save the PNG into a folder.

  3. You should now have a folder of one or more images:

    $ tree my_carousel_slides
my_carousel_slides
├── 1.png
└── 2.png

  4. Install imagemagick:

    brew install imagemagick

  5. Convert your image files to a single PDF:

    magick my_carousel_slides/*.png linkedin_carousel.pdf

  6. Create a LinkedIn post, click on add a Document, upload your PDF, give it a title

  7. Erm. That’s it.
