Instagram Carousel to LinkedIn Carousel

When you attach a PDF to a LinkedIn post, LinkedIn shows it in a viewer that people page through with arrows, and readers can usually open it full screen. The document gets a title you type when you upload it, and that title shows above the viewer, so write it like a headline rather than a file name.

LinkedIn accepts PDF, PowerPoint and Word files for document posts. A PDF is the safest choice for slides, because the layout and fonts stay exactly as you exported them. Images can't be posted as a swipeable carousel on LinkedIn, which is why this conversion is needed at all.

Keep the page size your slides were designed at. Instagram slides made square should stay 1080 x 1080, and slides made for the 4:5 feed should stay 1080 x 1350, so nothing gets padded. LinkedIn's viewer shows either shape. A lot of LinkedIn reading happens on desktop, where a portrait page leaves more empty space on both sides, which is one reason many LinkedIn decks are square.

This tool takes up to 20 images in one pass, which covers a full Instagram carousel. LinkedIn's own page limit for documents is much higher than that, so length is not the constraint.

Write the post text first. On Instagram the caption sits under the slides, while on LinkedIn the post text sits above the document and decides whether anyone opens it. A slide deck that relied on its Instagram caption for context needs that context moved into the LinkedIn post.

Check the cover page. LinkedIn shows it as the first thing in the viewer, so if your Instagram cover only works with a caption next to it, change it to a cover that states what the document is about.
