A LinkedIn carousel takes real work: a sequence of slides that teaches one idea step by step. After a few days in the feed it stops reaching new people. Pinterest is a better long term home for that work, because people search it for exactly this kind of how to content and pins keep surfacing long after they are published.
Upload the slides as images and this tool places each one on a 1000 × 1500 pin with your series title on top and a "3 / 8" counter, or stacks two to four slides on each pin. Carousels are usually exported as PDF; export the pages as PNG or JPG images first, then add them here. Everything runs in your browser and the slides never leave your device.
How to export a LinkedIn carousel as images
Most carousels are made in a design app and uploaded to LinkedIn as a PDF. Go back to the design app and export the pages as PNG instead; most apps offer this in the same download menu. If you only have the PDF, open it in a PDF viewer or an online PDF to image converter and save each page as an image.
Name the files in order, like slide-01.png, slide-02.png, so they sort correctly. This tool sorts numbers naturally, so slide-2 comes before slide-10 either way.
One slide per pin or stacked slides
One slide per pin gives each slide the most space and turns an eight slide carousel into eight pins, which spreads one piece of work across many days of pinning. The counter tells people there is a series, and the link on each pin can point to the full post or a blog version.
Stacking two to four slides per pin makes fewer pins that each tell more of the story. It suits short slides with large text. If you would rather publish the slides as one swipeable Pinterest carousel pin, use the Pinterest carousel maker.
