LinkedIn carousels aren't made of images anymore. The platform retired its native multi-image carousel for organic posts, so the only way to publish a swipeable carousel today is to upload a multi-page PDF (PPTX and DOCX also work) as a document post. LinkedIn automatically turns each page into a slide readers swipe through. To schedule one, you upload the document as usual, write your caption, then click the clock icon next to Post instead of posting right away. LinkedIn's native scheduler accepts it, typically up to about three months ahead.
Why a LinkedIn carousel is a PDF upload, not an image set
Every current how-to guide agrees on the replacement format: upload a document through "Add a document," and LinkedIn renders each page as a slide. Decktopus's carousel guide confirms the upload path accepts PDF, PPT, PPTX, DOC, or DOCX, and notes that separate image files still work for a post; they just create a static gallery, not a swipeable carousel. The sponsored multi-image Carousel API still exists, but only inside Campaign Manager for paid ads, not for a normal organic post. If a scheduling tool advertises "LinkedIn carousel support," check that it means document upload specifically, not a leftover reference to the old image-carousel format.
How to schedule a LinkedIn carousel PDF post, step by step
The native flow runs through the same composer you'd use to post immediately; scheduling is a different button at the end, not a separate tool.
The document itself isn't locked in until that final step, so you can swap the file or rewrite the caption right up until you confirm the schedule. PostEverywhere's scheduling breakdown confirms the native tool handles one post at a time and schedules roughly three months ahead; there's no bulk upload at the native level; that's a feature dedicated third-party tools add on top, not something LinkedIn's own composer does.
What LinkedIn's native scheduler doesn't do
- No bulk scheduling: one carousel, one time slot, one trip through the composer.
- No editing after you confirm the scheduled time; guides describe deleting and rescheduling as the only fix once a post is queued.
- No single calendar view across multiple queued posts; you check what's scheduled by reopening the clock icon and "View all scheduled posts" one at a time.
- Conflicting reports on whether personal profiles get native document scheduling the same way Company Pages do; verify directly in your own account rather than assuming either way, since current guides don't agree on this point.
Carousel PDF design specs that keep slides from looking cut off
| Spec | Recommendation | Platform limit |
|---|---|---|
| Slide dimensions | 1080×1080 or 1080×1350 px | Not fixed by LinkedIn |
| Slide count | 6–10 slides for full read-through | Up to 300 pages |
| File format | PDF (most reliable rendering) | PDF, PPT, PPTX, DOC, DOCX |
| File size | Keep it light for a faster upload | Up to 100MB on dedicated scheduling tools |
Decktopus recommends 6 to 10 slides for most topics, noting completion rates tend to drop past 12; LinkedIn's own platform limit of up to 300 pages is a hard ceiling, not a target. The 100MB file-size figure comes from Schedulala's own PDF-carousel feature announcement (13 Jan 2026), which also caps uploads at 300 pages, the same number Decktopus cites as LinkedIn's platform-level limit.
Where a document-only carousel leaves a multi-platform scheduler
Synapse posts text, images, and video to LinkedIn today, alongside eight other platforms, but it has no document-post type yet, so a PDF carousel still needs to go up through LinkedIn's own composer, scheduled natively or posted live, rather than through Synapse's queue next to your other accounts. That's worth knowing before picking a scheduler for your whole workflow, since "supports LinkedIn carousels" can mean different things depending on the tool: a true document upload, a convert-images-to-PDF flow, or no document handling at all. Synapse is accurate on the last one as of this writing. The LinkedIn scheduler pricing guide covers what dedicated and multi-platform tools charge for LinkedIn coverage overall, and posting to all your social media at once covers the workflow for everything Synapse does support: text, image, and video posts across LinkedIn and the rest of your connected accounts in one pass.
Can I still make a LinkedIn carousel with individual images?
No. LinkedIn's native multi-image carousel for organic posts is gone; uploading several photos now creates a static image gallery, not a swipeable carousel. A document upload (PDF, PPT, PPTX, DOC, or DOCX) is the only format LinkedIn turns into slides.
How far in advance can I schedule a LinkedIn carousel?
LinkedIn's native scheduler accepts documents roughly three months ahead, one post at a time, according to multiple 2026 scheduling guides. There's no published minimum lead time, so give yourself at least an hour as a safe buffer.
Can I edit a scheduled LinkedIn carousel post before it goes live?
Guides describe scheduled LinkedIn posts, document carousels included, as not editable once confirmed; the fix is to delete the scheduled post and recreate it with the correct file or caption.
Do LinkedIn carousel PDFs work the same way on Company Pages and personal profiles?
Current guides disagree on whether personal profiles get native document scheduling the same way Company Pages do. Check directly in your own account rather than assuming either way. This is one of the few LinkedIn scheduling details 2026 sources don't agree on.
Can a social media scheduler post a LinkedIn carousel for me?
Only a scheduler built to upload documents, not just images, can do it; confirm that directly rather than assuming "LinkedIn support" includes carousels. Synapse posts LinkedIn text, images, and video today but has no document-post type yet, so a carousel PDF still goes up through LinkedIn's own scheduler.
