LinkedIn Carousel
A multi-slide post created by uploading a PDF, which LinkedIn renders as a horizontally swipeable deck in the feed. Technically a document post.
A LinkedIn carousel is a post format created by uploading a PDF file, which the feed displays as a swipeable slide deck. Users tap or swipe through each page, and that swipe action drives some of the highest dwell time of any format on the platform.
Carousels work because they front-load value across multiple slides. A typical structure: cover slide with a bold promise, 5-8 content slides that each deliver one idea, and a final CTA slide that asks for a comment, follow, or save. Aspect ratios of 1:1 (square) or 4:5 (portrait) take the most feed real estate.
The format is unusually forgiving. Even posts with modest written copy can perform well if the deck itself is strong, because LinkedIn's algorithm rewards the swipe-time per impression. Save and share rates also tend to be higher than for text posts, since carousels function like mini reference documents.
Making carousels manually involves designing in Figma, Canva, or Keynote, exporting to PDF, and uploading. The friction is real: most creators batch carousel production into a weekly session rather than designing one at a time.
Propelr includes a native carousel builder that turns a post outline into a designed PDF without leaving the app, which removes the export-import loop. The format itself, though, is platform-agnostic — any well-designed PDF uploaded as a document post becomes a carousel.
