Carousel Converter

Because you already did the hard part. A carousel that worked on one platform (a framework, a checklist, a teardown) usually works on the other too; the audiences overlap less than you'd think, so it isn't even a rerun for most followers. The only real barrier is the format mismatch: LinkedIn wants a PDF, Instagram wants images. That's the whole job this tool does.

LinkedIn has no carousel post type. What people call a LinkedIn carousel is a document post: you attach a PDF and LinkedIn shows it in a viewer that people page through with arrows. 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. Several images in one LinkedIn post show as a photo grid, not as pages people flip through, which is why the conversion is needed.

For Instagram, portrait 1080 x 1350 (4:5) is the right answer for almost everyone: it takes up the most screen space in the feed. Square 1080 x 1080 still works and suits designs that were built square. Instagram carousels support up to 20 slides, so even a long LinkedIn document fits in one post.

For LinkedIn, keep the size your slides were designed at, so nothing gets padded: square slides stay 1080 x 1080 and 4:5 slides stay 1080 x 1350. LinkedIn's viewer shows either shape, and a lot of LinkedIn reading happens on desktop, which is one reason many LinkedIn decks are square.

Going to Instagram, check text size. Many LinkedIn document views happen on desktop, where small labels are legible; Instagram is nearly all phones. If you have to pinch-zoom to read a slide at phone width, so does everyone else. The cover needs a second look too: on Instagram the first slide is the whole pitch, so swap a quiet LinkedIn cover for one that states the payoff.

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