If your LinkedIn PDF carousel looks blurry, the cause is usually in the file you exported: images saved smaller than the size they are shown at, compression applied during export, text flattened into a picture, type that is too small or too thin, or a page size that forces heavy scaling on a phone. LinkedIn may also compress or re-render uploaded documents, which you can't control, so the practical goal is to upload the sharpest source you can. Below: the likely causes, a symptom-to-fix table, export settings and a pre-upload checklist.
Seven likely causes of a blurry carousel
- Low-resolution images. A screenshot or photo saved at 600 px wide and stretched across a 1080 px page will look soft wherever it appears.
- Image compression on export. Many export dialogs offer a smaller-file option that lowers image quality to save space, and some apply it by default.
- Text turned into images. If each page was exported as a JPG and the images were combined into a PDF, your text is now pixels. It can't be sharper than the image it sits in.
- Small text. Text below roughly 28 px on a 1080 px wide page becomes tiny on a phone, and tiny letters read as blurry even when they are technically crisp.
- Thin fonts. Light and hairline weights have strokes that get thinner than a screen pixel once the page is scaled down, so they look smeared.
- Wrong page size or scaling. A 16:9 slide or an A4 page with small type is scaled down to fit a phone, and everything on it shrinks with it.
- Very large files. A file near the size limit is usually packed with uncompressed photos. It is slower to open, and since LinkedIn may compress uploaded documents, oversized images gain you nothing.
Viewing on a phone adds to all of these. A phone shows each page at a fraction of its designed size, so a page that looked fine on your monitor can look soft in your hand. Judge sharpness on a phone.
Troubleshooting table: symptom, cause, fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Text looks fuzzy at every zoom level | Pages were exported as images, so text is pixels | Re-export from the original file with text kept as text |
| Photos and screenshots look soft; text is fine | Low-resolution images or compression on export | Replace with larger originals; turn off image compression |
| Everything looks small and soft on phones | Landscape or A4 page scaled down to phone width | Switch to a 4:5 portrait page and enlarge the type |
| Thin letters break up or smear | Light or hairline font weights | Use regular weight or heavier for body text |
| Small labels can't be read | Text under about 28 px on a 1080 px page | Raise body text to 32 to 40 px; move details into the post text |
| Chart edges look jagged | Chart pasted in as a small bitmap | Insert it as a native chart or vector graphic |
| File is huge and slow to open | Uncompressed photos at print resolution | Resize photos to about twice their displayed size |
| Pages appear at different sizes | Mixed page sizes in one PDF | Use one page size for every page |
The last row matters for a specific reason: LinkedIn's help center says PDFs with pages of different sizes must be fit to the same page size, so any page that doesn't match will be resized. For the page sizes themselves, see our LinkedIn carousel size guide.
Check whether your text is real text
Real vector text stays sharp at any zoom level in the PDF itself. LinkedIn may still compress or re-render the document, but if your file contains vector text, no blur is baked in before you upload. This test takes a minute:
- Open the exported PDF in any PDF viewer and zoom to 400 percent or more on a headline.
- If the letter edges stay smooth, the text is vector. If you see blocky squares or a soft halo, the page is an image.
- Try selecting a word or searching for it. Text you can highlight and search is real text; if nothing highlights, the page was rasterised.
- Zoom in on a photo at the size it appears on the page. If it already looks soft there, it will look worse on LinkedIn.
If the test fails, fix the source file rather than the PDF. For more on live text, read editable PPTX vs image slides.
Export settings that keep pages sharp
Menu names change between versions and operating systems, so treat these as pointers to the right setting rather than exact paths.
- PowerPoint: when saving as PDF, open the options and choose "Standard (publishing online and printing)" rather than "Minimum size". Under File, Options, Advanced, you can also turn off image compression for the file and set the default resolution to high fidelity before you export. If your version labels these differently, pick the option aimed at print quality rather than a smaller file.
- Keynote: export to PDF and set Image Quality to the highest setting.
- Google Slides: downloading as a PDF offers few or no quality controls, so quality depends on the images you placed. Insert large originals.
- WPS: export to PDF and, if your version shows an image quality option, choose the higher setting.
Two habits apply in every tool. Supply each image at about twice the pixels it occupies on the page, so a full-width image on a 1080 px page should be around 2160 px wide. And save screenshots and graphics with text as PNG, keeping JPG for photos.
Pre-upload export checklist
- Every page uses one size, ideally 4:5 portrait.
- Body text is at least 32 px on a 1080 px page (16 pt on a 7.5 inch slide), in regular weight or heavier.
- Text is selectable in the exported PDF, not part of an image.
- Photos are about twice their displayed size; screenshots are PNG.
- Image compression is off, or set to high quality, in the export dialog.
- Fonts are embedded, so nothing is replaced by a thinner substitute.
- The file is well under LinkedIn's limits (its help center lists 100 MB and 300 pages) and ideally a few megabytes.
- You have opened the PDF on your phone and read every page at arm's length.
Already posted a blurry carousel?
LinkedIn's help center says you can edit a document post's title and description after posting, but not the file itself. Replacing a blurry carousel therefore means reposting:
- Export a corrected PDF using the checklist above.
- Copy your post text and note any comments you want to answer.
- Delete the original post and publish a new one with the corrected file.
If the original post already has good discussion, you might leave it up and use the sharper file next time instead.
Exporting a sharp LinkedIn carousel with AI
Our AI studio is built to produce high-quality, editable slides. The article-to-carousel workflow lays out LinkedIn pages at 4:5 and exports them as a PDF document, which takes care of the page size and scaling causes above. Paste up to 100,000 characters, upload a .docx, .pdf, .txt or .md file, or import a URL, then review and edit the page-by-page outline; drafting it uses no credits. Generation costs 2 credits per page with AI images included, the total is shown before you start, and credits come back automatically if a generation fails. Exports carry a small "AI-generated" label. Still run the phone check before posting.
The remote team carousel example turns a long post about scaling a remote team into an eight-page 4:5 carousel, with one lesson per page.
FAQ
Why does my LinkedIn carousel look blurry after uploading?
The cause is usually in the file: images smaller than the size they are shown at, compression applied during export, or text that was turned into a picture. Small or thin fonts and a page size that forces heavy scaling make it worse. LinkedIn may also compress or re-render uploaded documents, so a file that is sharp at the source holds up better.
What resolution should a LinkedIn carousel PDF be?
Text and shapes saved as vectors have no fixed resolution and stay sharp at any zoom. Resolution applies to the images inside. A practical rule is to supply each image at about twice the pixel size it occupies on the page, so a full-width image on a 1080 × 1350 page would be about 2160 pixels wide.
Should I upload a PDF or a PPTX for a LinkedIn carousel?
LinkedIn's help center lists both as supported formats. PDF is the usual choice for carousels because fonts and layout are fixed when you export, so what you checked on screen is what you upload. With a PPTX, the result depends on how the file is rendered after upload.
How do I fix a blurry LinkedIn carousel I already posted?
According to LinkedIn's help center, you can edit a document post's title and description but not replace the file. To use a sharper version, export a corrected PDF, delete the original post and publish a new one. Copy your post text and note any comments you want to reply to before deleting.
