LinkedIn Carousel Not Displaying Properly? What to Check

A carousel that looked right in your design tool can arrive on LinkedIn cropped, blurry, oddly typeset, or as a grey rectangle that never loads. Annoying, but rarely mysterious.

The key thing to understand is that LinkedIn does not show people your PDF (Portable Document Format — the fixed-layout file type meant to look the same everywhere). It converts your upload on its own servers into a set of flat page pictures and shows those inside a swipeable viewer. Fonts survive only if they were embedded, layers and transparency are flattened, colour is remapped for screens, links inside a page stop working, and the page shape is squeezed into LinkedIn’s frame rather than the other way round.

So nearly every display fault traces back to something in your file that did not survive that trip. Find your symptom below, apply the fix, re-export, and post again.

My pages are cropped or have bars down the sides — what causes that?

This is an aspect ratio problem — aspect ratio simply means the shape of the page, how wide it is compared to how tall. LinkedIn shows your document inside a viewer of a fixed shape, and your page must fit that frame. If the shapes disagree, you get empty bars at the sides or top, or the page shrinks to a small block surrounded by space.

The worst version is mixed page sizes inside one file. If page 1 is square, page 2 portrait and page 3 a stray landscape slide, the viewer resizes on every swipe and the whole thing jumps around.

The fix. Decide on one page size before designing anything, and export every page at exactly those dimensions. Do not mix orientations, and do not let one slide sneak in at a different size because you built it elsewhere. Square or portrait is a design decision — a sibling article covers sizes — but consistency matters more than which you pick.

Why is my text cut off at the edges?

Three causes, and they need different fixes.

Your content sits too close to the page edge

Conversion and scaling can shave a hairline off the outside of a page. If your headline starts four pixels from the edge, that is enough to clip a letter. Build a proper margin all the way round.

LinkedIn’s own interface is sitting on top of your page

The viewer draws its own controls over the document: a page counter, arrows for moving between pages, and depending on the device a title strip or download control. Anything underneath those is hidden. The bottom strip is the usual casualty — exactly where people put their name or call to action. Treat the outer edge as a no-go zone and keep the bottom band clear.

A text box overflowed on export

PowerPoint and Google Slides let a text box overflow or auto-shrink its text, and what you see in the editor is not always what lands in the PDF. Always open the exported file in a plain PDF viewer and read it there. Checking the editor is not checking the file.

Why do the fonts look wrong or get swapped?

This one has a single cause almost every time: the fonts were not embedded.

A PDF can either carry the actual font inside the file, or simply name it and assume whatever opens it has a copy. If your font is only installed on your machine and was not embedded, LinkedIn’s converter substitutes something else. The substitute has different letter widths, so lines re-flow, headlines wrap in new places, and carefully placed text pushes out of its box.

Fix one: turn embedding on. Most design tools embed by default. Office applications frequently do not — look for an option like “embed fonts in the file” in the export dialog. Note that some fonts are licensed in a way that forbids embedding, and exporters drop them quietly. If one font keeps vanishing whatever you tick, swap it.

Fix two: convert text to outlines. Turning text into shapes (also called outlines, curves or paths) means it can never be substituted, because there is no font left to substitute. The trade-off is real: outlined text is no longer selectable or readable by a screen reader. The accessibility article in this cluster covers that.

How to check. Open the exported PDF and look at its document properties, where there is normally a Fonts tab. Every font listed should say embedded, or embedded subset. Anything that does not will be replaced.

LinkedIn rejected my file — what should I check?

Run down this list in order. The first four cover most rejections:

• File type. Document posts accept PDF and common office formats such as PowerPoint and Word. An image file is not a document — a PNG gives you an image post, not a swipeable carousel.
• File size. There is a maximum, and photo-led decks pass it easily. Compress the images inside the file before exporting, rather than squashing the finished PDF.
• Page count. There is a cap here too. Check LinkedIn’s Help Center for the current figure.
• Password protection. An encrypted PDF, or one with editing restrictions applied, cannot be converted. Remove the protection and export a clean copy.
• Unusual file internals. Layers, interactive forms, embedded video or an exotic colour profile can all fail conversion. Re-export as a plain, flattened PDF.
• The file name. A document post shows a title, often taken from your file name. Give it one that reads well in a feed, not Untitled-1-final-v3.

Why is my preview blank, grey or stuck on processing?

Conversion happens after upload and it is not instant. A large, photo-heavy file takes a while, so the first step is patience: wait, refresh, and check on another device before deciding it has failed.

If it is still blank well after posting, conversion genuinely failed. The triggers are the same ones that cause outright rejection — encryption, a scan at enormous resolution, unusual transparency effects, missing fonts. Re-export a smaller, flatter file and post again.

There is also a boring version of this: page 1 really is blank. An empty artboard, a template guide page, or white text on a white background all export as a blank first page. Open the file yourself and look.

Why is the wrong page showing as the cover?

The cover is simply page 1, and LinkedIn gives you no way to choose a different one. So if the wrong thing is showing, the file order is wrong. Common reasons:

• A blank or template page was exported as page 1 without you noticing.
• Your design tool exported artboards in canvas order — usually left to right, top to bottom — rather than the order you created them.
• You exported a page range that started in the wrong place.

The fix is always the same: reorder the pages in the source file, re-export, and check the result in a PDF viewer before uploading.

Why do the colours look dull or different?

If your document was set up for print, it is probably in CMYK — the four ink colours used by printing presses. Screens use RGB, which is red, green and blue light. Converting between them shifts colours, usually reading as duller and flatter, especially with bright brand colours.

The fix. Set your document to RGB from the start and export with a standard sRGB screen profile. Converting a print file at export time helps, but starting in the right colour space gives a truer result.

Why is my carousel blurry?

Blurriness is nearly always a placed photo or screenshot rather than the text, because text usually exports as sharp vector shapes. Check for:

• Low resolution images scaled up. A small screenshot stretched to fill a page will never be sharp.
• An aggressive export preset. Options named “smallest file size” or “web” compress images hard.
• Double compression. Exporting a compressed PDF, then shrinking it again with another tool, compounds the damage.

If you are hitting the size limit while trying to keep quality, drop some heavy photos rather than crushing all of them.

My multi-image post looks wrong — is that the same problem?

No, and it is worth separating the two, because people call both carousels. A document post is the PDF one described above. A multi-image post is a set of separate image files — in Kalovio, two to nine — in one post the reader swipes through. No PDF, no conversion, no font embedding, so none of the fixes above apply. Its faults are different:

• Mixed shapes. Images that are not all the same aspect ratio get fitted into one shared frame, and a taller image loses its top and bottom. Export them all at identical dimensions.
• Wrong order. The order you upload is the order they appear, with no reordering afterwards.
• One rejected image. An unsupported format or oversized file in the middle of the set can fail the whole post.

Both are also separate from LinkedIn’s carousel ads, a paid advertising format with its own rules. If you are reading advertising specifications while troubleshooting an ordinary post, you are on the wrong page.

Which symptom means which fix?

Can I fix a carousel that is already posted?

Not the file itself. You can edit the caption on a published post, but you cannot swap the document out from under it. That leaves two options, neither lovely: delete the post and publish the corrected version, losing its reactions and comments, or leave it and post the fixed version later.

So a two-minute check before posting beats any fix afterwards. Open the exported file in a plain PDF viewer, not your design tool, and confirm: every page is the same size, page 1 is the cover you meant, nothing is clipped, the fonts are yours, the images are sharp.

How do I publish the corrected file?

Once the file is right, publishing is the simple part. With Kalovio you upload the PDF to your document library, then ask your AI assistant to publish it with whatever caption you want. It goes out as a document post through LinkedIn’s official API, and you approve the exact wording first.

None of that replaces the check itself. Whatever you publish with, the file is what LinkedIn converts, so the file is where the fix lives.
