Respect how LinkedIn actually renders a “carousel”
Document post ≠ multi-photo post
A native multi-image post and a document post are different composers. The document path is what people mean by “LinkedIn carousel”: a PDF whose pages display as swipes. Our ZIP of 1080×1080 CSS squares (≈2160 px captured) is the right still size for those pages. Open the slides in Preview (macOS), Photos, Google Drive, or any “print to PDF” tool, one image per page, export PDF, upload as a document. Skip this hop and you are posting a gallery, which LinkedIn treats differently and often less generously in reach folklore — regardless, the PDF path is the one tutorials describe.
What belongs on a professional swipe
Thought-leadership packs fail when every frame is a paragraph screenshot. Photographs, simple diagrams exported as images, and quote cards designed elsewhere work. This tab will not set Inter or your brand kit. Bring already-designed cards as PNG, or keep the pack photographic (event, product, office) and put the argument in the LinkedIn caption. B2B buyers still swipe when the first frame earns it: a clear visual hook, not “best carousel maker” as a title card.
Confidential decks
Unreleased metrics and customer photos should not sit in a random design SaaS. Local slice plus a PDF you created on disk is an NDA-friendly path. Filename branding on the free tier is a stem change — rename before the PDF so the document properties do not look sloppy. Sixteen frames is enough for a lesson and too many for a humblebrag; five to twelve is the usual engagement window people cite, with evidence that is more folklore than physics. Trim anyway.
