For organic LinkedIn image posts, export at 1080 px wide and stay inside the 3:1 to 4:5 ratio range, then save 1200×627 px separately for link previews. The safest everyday portrait preset for B2B feed posts is 1080×1350 px because it survives mobile cropping. Pick one export size before design starts.
Most upload problems trace back to mixing image posts with URL previews or paid placements inside the same calendar slot. The practical job is to lock the export size before the designer opens the file, then check the crop and text legibility on a phone before the post enters review.
The four points below set the stake: organic photo specs, link preview specs, and document slides each behave differently, and a single export rarely covers all three.
- Organic photo posts can use 1080 px width, while 552×276 px is only the official minimum.
- The 4:5 ratio gives the tallest organic feed image before LinkedIn can crop the post.
- Link previews use a 1.91:1 frame, so 1200×627 px should be prepared separately.
- Images that rely on small text should be checked on mobile before scheduling.
Use these LinkedIn image sizes first
The safe default for image-led organic posts is 1080×1350 px, and link previews should be exported at 1200×627 px. According to LinkedIn’s photo-sharing guidance, organic photo posts allow up to 5 MB with a 552×276 px minimum and an aspect ratio range of 3:1 to 4:5. Anything outside that range gets centered and cropped.
| Placement | Export size | Aspect ratio | Best use case |
|---|---|---|---|
| Standard organic photo | 1080 px width, 5 MB max | 3:1 to 4:5 | Single-image feed posts |
| Portrait feed post | 1080×1350 px | 4:5 | Maximum vertical space on mobile |
| Square post | 1080×1080 px | 1:1 | Cross-channel reuse without recropping |
| URL link preview | 1200×627 px | 1.91:1 | Driving clicks to a web page |
Choose aspect ratio from the post goal
Pick the ratio from the job of the post before the designer opens the file. A portrait image gives more vertical space in the feed, while a link preview belongs in the 1.91:1 frame. Mobile devices accounted for more than 63% of web page requests in December 2024, so small text and edge-heavy layouts are a weak starting point for DACH and global B2B audiences.
- 1080×1350 px (4:5) when one strong idea has to stop a mobile scroll.
- 1080×1080 px (1:1) when the same creative must work across several social channels without a separate crop.
- 1200×627 px (1.91:1) when the post’s main job is to send people to a web page through a URL preview.
- Document post when several slide-style pages need to stay readable after upload.
If you want this decision baked into a repeatable production rhythm, our weekly content system shows where the export step actually fits.
Why does LinkedIn crop some uploads?
LinkedIn crops when an uploaded photo falls outside the allowed organic image ratio range. The platform centers the image, so important text near the edges is the first thing at risk. The crop problem usually starts before upload because the creative was designed taller than 4:5 or wider than 3:1.
Multi-photo posts add another variable because the first image decides how the rest of the set is arranged. A landscape first image places the remaining photos below it. A portrait or square first image pushes the remaining photos into a side stack. URL preview images behave differently, since Page-post previews can show non-1.91:1 images on mobile with subtle white padding when the source is wider than 200 px.
The practical review is short: keep faces, logos, and headline text near the center, and preview the post on a phone before approval. A simple approval SOP closes that gap before the post goes live.
Multi-photo layout rule: If the first image in a multi-photo post is landscape or shorter than 4:3, it appears on top with the others below; if it is portrait, square, or longer than 4:3, it sits in the left column with the rest stacked to the right. Maximum 20 photos per post.
Why does my LinkedIn image look blurry?
Blurry LinkedIn uploads usually start with low resolution, tiny source files, or text that is too fine for mobile display. Compression makes those weaknesses more visible after upload. LinkedIn’s Page guidance recommends high-resolution JPEG for image quality on Page and Career Page surfaces, with PNG or JPEG files capped at 3 MB.
- Image looks soft after upload: export again from the original file at the final ratio instead of resizing a downloaded preview.
- Text-heavy creative: reduce copy and make the main words large enough to survive a phone screen.
- Photo-based post: use a high-quality JPEG export, since LinkedIn prefers high-resolution JPEG for image quality.
- Logo or small UI screenshot: keep it away from the crop edge and test a second export before publishing.
- File near the upload ceiling: controlled pre-compression usually produces a cleaner result than letting the platform do all the work.

Link previews have their own rules
A LinkedIn link preview is not the same thing as uploading an image post. The preview depends on the page’s metadata, and LinkedIn may cache what it first sees. Prepare the creative at 1200×627 px because the preview frame is 1.91:1, and keep the source image above 200 px wide or LinkedIn can fall back to a small thumbnail treatment.
If the preview image is missing entirely, the web page probably lacks the Open Graph or oEmbed data LinkedIn uses to pull title and image, and recent metadata changes may need up to 48 hours to refresh after a page was previously shared. Publishing tools blur this further because a scheduled link post and an uploaded image post look similar inside a calendar, so review should confirm which post type is actually queued. Our automation workflow without sounding automated walks through that distinction at the queue level.
Which adjacent LinkedIn formats need different sizes?
Several LinkedIn placements look like feed images but use different specs. Organic photo posts, single image ads, carousel ads, and document posts should not share one export blindly. Document ads allow files up to 100 MB and 300 pages, with PDF as the recommended format for the highest-quality upload.
| Placement | Recommended size | File limit | When to use |
|---|---|---|---|
| Single image ad | 1200×628 px, 1.91:1 | 5 MB | Paid landscape feed creative |
| Carousel ad card | 1080×1080 px, 1:1 | 10 MB per card | 2–10 paid swipeable cards |
| Document upload | PDF preferred | 100 MB / 300 pages | Multi-page slides that must stay readable |
Square or vertical creative built for organic feed can crop awkwardly when reused in a single image ad, which is why ad teams keep the landscape master separate from the 4:5 portrait master.
Three LinkedIn presets cover most posts
The production setup most B2B teams need is smaller than image-size cheat sheets suggest. Treat organic images, link previews, and document-style slides as three separate export families and most blur and crop problems disappear before they reach a reviewer.
A 4:5 portrait preset gives the largest organic feed canvas inside LinkedIn’s photo-post limit. A 1.91:1 link-preview preset prevents website cards from being judged by organic image rules. A PDF export path keeps multi-slide posts on their own track instead of forcing them through single-image production.
Build three saved presets this week: 1080×1350 px for feed images, 1080×1080 px for reusable square posts, and 1200×627 px for link previews. Add a phone-screen check before approval so text size and crop safety are caught before scheduling.
Frequently Asked Questions (FAQ)
Can I post an image and a URL in the same LinkedIn post?
No, not as a single combined creative. Standard LinkedIn sharing treats uploaded photos and URL previews as different post types, so a post with a URL pulls a preview card instead of using your uploaded image as the main visual. Pick one primary post type per slot and stick with it.
Is JPG or PNG better for LinkedIn posts?
High-quality JPEG is the safer default for photo-based LinkedIn visuals. LinkedIn’s Page guidance recommends high-resolution JPEG over PNG for image resolution on those surfaces. PNG can still make sense when the design depends on flat graphics, sharp edges, or screenshots where compression artifacts would be visible.
What size should LinkedIn carousel cards be?
1080×1080 px is the recommended default for paid LinkedIn carousel cards. LinkedIn’s carousel ad specs are built around a 1:1 card. Organic slide-style posts are better treated as document uploads instead of exported image cards, because document posts preserve text legibility better than flattened image slides.
Should I use a document post instead of image slides?
Yes, when the content has several pages and small details must stay readable. LinkedIn allows document uploads up to 100 MB and 300 pages, and the official guidance recommends converting to PDF whenever possible for the highest-quality upload. Image slides flatten faster but lose detail under platform compression.
How do multi-image LinkedIn posts get arranged?
The first image acts as the layout driver. If it is landscape, LinkedIn places it above the rest of the set; if it is square or portrait, it sits beside a stacked column of the other images. Keep the first image inside the 4:5 limit so the entire post stays out of the crop zone.
What if my LinkedIn link preview image is outdated?
Check the web page metadata first, then wait for LinkedIn’s cache to refresh. LinkedIn pulls preview details from Open Graph or oEmbed data, and changed preview information may take up to 48 hours to update after the page was previously shared. If the new preview still does not appear, recheck the OGP tags before resharing.
