How many images can you post on LinkedIn?
LinkedIn allows up to 9 images in a single multi-image post, displayed as a swipeable gallery. Separately, carousels (uploaded as PDF documents) support up to 20 slides. A standard single-image post is just one image; the multi-image and carousel formats are distinct upload options within the composer, not extensions of the same limit.
It's worth separating LinkedIn's two multi-image options because they behave differently and serve different purposes, and conflating them leads to picking the wrong format. A multi-image post is a quick gallery of up to 9 separate photos or graphics, swiped through the same way a carousel is, but each image is independent — there's no enforced reading order, no consistent template requirement, and no PDF export step. It's well suited to a set of standalone photos, like event shots or product angles, where each image stands on its own.
A carousel is structurally different: it's a single PDF document, uploaded as one file, where slides are explicitly designed to be read in sequence and typically share a consistent visual template. This is the format built for step-by-step frameworks, story arcs, or any content where slide order matters and each slide builds on the last. The 20-slide cap gives meaningfully more room than the 9-image cap, but more slides isn't automatically better — most well-performing carousels land in a much tighter 6-10 slide range, since completion rate drops the longer the swipe sequence runs.
The practical decision: if the images are independent and order doesn't matter, use the multi-image gallery. If the content tells a sequential story or walks through steps where order and visual consistency matter, use a carousel instead, and treat the 20-slide ceiling as a hard limit to design within rather than a target to hit.
A common mistake is uploading a sequential, step-by-step graphic as a multi-image post because it's faster to prepare, only to have viewers swipe through the images out of the intended order since a multi-image gallery has no enforced sequence the way a carousel's fixed PDF page order does. Save the multi-image format for genuinely standalone visuals, and use a carousel whenever order matters.
Key Points
- Multi-image posts support up to 9 independent images in a swipeable gallery
- Carousels (PDF uploads) support up to 20 slides, designed to be read in sequence
- Multi-image galleries suit standalone content; carousels suit sequential, templated content
- Most high-performing carousels use far fewer than 20 slides, typically in the 6-10 range
Example
An event photographer uploads 9 photos from a conference as a multi-image gallery post since each photo stands alone, while the same week posts an 8-slide carousel walking through a networking framework, using the carousel format specifically because that content needs to be read start to finish in order.
Related Questions
Is a multi-image post the same as a carousel on LinkedIn?
No — a multi-image post is a gallery of up to 9 independent images with no required order, while a carousel is a single PDF document of up to 20 slides designed to be read sequentially.
What's the best number of images for a multi-image LinkedIn post?
There's no fixed ideal, but 3-6 well-chosen images tend to hold attention better than maxing out at 9, since a gallery that's too long risks the same drop-off in completion that overly long carousels see.
