You need a LinkedIn post mockup. Maybe for a case study. Maybe for a pitch deck. Maybe to show a client what their content will look like before it goes live. Whatever the reason, taking screenshots is messy and editing them in Photoshop takes too long.
This tool lets you build a pixel-perfect LinkedIn post mockup from scratch. Change the name, headline, avatar, post text, reactions, comments count, even the reaction types. Add a single image or build a full carousel. Switch between light and dark mode. Toggle mobile and desktop views. When it looks right, download it as a crisp PNG.
How to Use the LinkedIn Post Mockup Generator
The tool shows you a realistic preview of your post before it goes live. Here is how to use it step by step.
- Step 01
Choose your post type
Pick the type of LinkedIn post you want to preview. You can choose from text only, image post, carousel, poll, video, or article share. Each type has a different layout on LinkedIn so picking the right one matters.
- Step 02
Enter your post content
Paste your post text into the editor. Add your name, headline, and profile picture. If your post includes an image, upload it. If it is a carousel, add your slide previews. The tool needs the same details LinkedIn shows in the feed.
- Step 03
Preview your mockup
Click generate and the tool creates a realistic mockup of your post. It looks exactly like a real LinkedIn post in the feed. You can see how much text shows before the "see more" cut off and how your image sits in the layout.
- Step 04
Switch between desktop and mobile views
Toggle between desktop and mobile previews. Your post will look different on each device. Most LinkedIn users browse on their phones. So checking the mobile view is just as important as the desktop version.
- Step 05
Download or adjust
Download your mockup as a PNG or PDF. Or go back and tweak the text, swap the image, and preview again. Keep adjusting until it looks exactly the way you want. Then publish the real post on LinkedIn.

Who This Tool Is For
Anyone who posts on LinkedIn and wants to preview their content before publishing can use this tool. Here is who benefits the most.
-
Social media managers
You manage LinkedIn accounts for multiple brands. You need to check how each post looks before it goes live. This tool lets you preview and download mockups for every client in minutes. No more guessing and no more embarrassing formatting mistakes.
-
Agency teams
You create LinkedIn content for clients and need their approval before publishing. A realistic mockup is worth more than a paragraph in a shared document. Send your clients a preview that looks exactly like the final post. Cut approval time and reduce revision rounds.
-
Freelance content creators
You write LinkedIn posts for businesses and build your portfolio as you go. Mockups let you show potential clients what their posts will look like. And you can add past work to your portfolio even if you do not have access to the live posts anymore.
-
Founders and solopreneurs
You handle your own LinkedIn presence and want every post to look polished. You do not have a design team to review things. This tool is your second pair of eyes. Preview your post, catch mistakes, and publish with confidence.
-
Content teams
You plan LinkedIn posts as a group and need a clear way to review content together. Mockups give your team a shared reference point. Everyone sees the post the way the audience will see it. Feedback is faster and more specific.
Why Post Mockups Matter
A mockup is a realistic preview of your content before you publish it. And on LinkedIn, that preview can save you from a lot of problems.
-
First impressions happen fast
People scroll through their LinkedIn feed quickly. If your post looks messy or the formatting feels off, they scroll right past it. You get one shot at a good first impression. A mockup helps you nail it.
-
LinkedIn does not show you a preview
When you write a post on LinkedIn, you type in a plain text box. There is no preview button. You cannot see how your image will crop, where the text will cut off, or how the layout will look. A mockup tool fills that gap.
-
Formatting mistakes cost you reach
A post with broken line breaks or a badly cropped image gets less engagement. Less engagement means the algorithm shows your post to fewer people. One formatting mistake can cut your reach in half.
-
Clients want to see what they are paying for
If you manage LinkedIn accounts for clients, they want to approve posts before they go live. A screenshot of a text editor does not inspire confidence. But a realistic mockup that looks like an actual LinkedIn post does.
Desktop vs Mobile Preview Differences
Your post looks different on a laptop than it does on a phone. And most of your audience browses LinkedIn on mobile. Here is what changes between the two views.
-
The text cutoff is different
The desktop shows about three lines of text before "see more." Mobile shows even less. Your opening hook might be fully visible on desktop but cut off on mobile. Always check both.
-
Images crop differently
Desktop displays images at a wider aspect ratio. Mobile crops tighter and shows less of the top and bottom edges. If you have text overlaid on an image, make sure it stays visible on both views.
-
Carousel slides appear smaller on mobile
The swipe area is narrower on a phone screen. Text on your slides needs to be large enough to read without zooming in. If you design for desktop only, mobile users will struggle to read your slides.
-
Video thumbnails resize
On desktop, video thumbnails show in a wide rectangle. On mobile, they take up the full width of the screen but appear shorter. Make sure your thumbnail works at both aspect ratios.
-
Engagement buttons shift
The like, comment, and share buttons look slightly different on each device. This does not affect your content directly. But if you are creating mockups for a pitch deck or case study, matching the right button layout adds authenticity.
-
Link previews change size
When you share a URL in your post, LinkedIn generates a preview card. That card looks bigger on desktop and gets compressed on mobile. The headline might get cut short on a phone screen. Check your mockup on both devices to make sure the preview card shows your full headline and a clear image.
Client Presentation and Portfolio Use Cases
Mockups are not just for checking your own posts. They are a powerful tool for anyone who creates content for other people.
-
Agency client approvals
If you run a social media agency, you know the approval process can be painful. You write a LinkedIn post in a Google Doc and send it to the client. They read it in a plain text format and say "looks fine." Then you publish it and they complain that the image looks wrong. A mockup solves this. Send the client a realistic preview of exactly what the post will look like in the feed. They see the profile picture, the text layout, the image. There are no surprises after publishing. And you save yourself from the back and forth emails. "Can you make the image bigger?" "Why does the text look different?" These questions disappear when the client sees a real mockup before you go live.
-
Freelancer portfolios
If you are a freelance content writer or social media manager, your portfolio needs to show results. Screenshots of live posts work well. But what about posts that are still in draft or posts you wrote for clients who do not want to share access? Create mockups of those posts. They look just like real LinkedIn posts. Add them to your portfolio and show potential clients the quality of your work. You can even add realistic engagement numbers to show what a high performing post looks like with your writing style.
-
Pitch decks and proposals
When you pitch a new client, showing them what their LinkedIn content could look like is more powerful than describing it in a slide. Create a mockup with their brand name, their profile picture, and sample post copy. It makes your proposal feel real and tangible.
-
Content calendars and planning
Some content teams plan LinkedIn posts weeks or months in advance. A spreadsheet full of draft text is hard to visualize. But a folder of mockups showing each post in feed format makes the content calendar come alive. Teams can review and give feedback on the actual look of each post. This approach also helps with content variety. When you see all your upcoming posts as mockups, you can quickly spot patterns. Too many text posts in a row? Not enough images? The visual layout of mockups makes these gaps obvious in a way that a spreadsheet never will.
Team Collaboration Workflows
When multiple people work on LinkedIn content, things get messy fast. Mockups bring order to the process.
-
Content writers create drafts
The writer creates the post copy and builds a mockup. They share the mockup with the team instead of sharing raw text in a document. Everyone sees the post the way the audience will see it.
-
Designers review the visuals
If the post includes an image or carousel, the designer can check how it looks inside the actual feed layout. They catch cropping issues and readability problems before the post goes live.
-
Managers approve the final version
The manager reviews the mockup and approves it. Or they ask for changes. Either way, everyone is looking at the same thing. No more confusion about how the post will look after publishing.
-
Clients sign off with confidence
For agencies, the client sees the mockup and approves it. There is no gap between what they approved and what gets published. This cuts revision rounds and builds trust.
-
Freelancers speed up feedback loops
Instead of going back and forth on text formatting, the freelancer shares a mockup. The client gives feedback on the actual visual. Revisions are faster and more specific.
Dark Mode vs Light Mode Mockups
LinkedIn offers both light and dark display modes. Your post needs to look good in both.
-
Light mode
This is the default white background. Most people are familiar with this view. Text is dark on a light background. Images stand out clearly. This is the standard view you probably think of when you picture a LinkedIn post.
-
Dark mode
This uses a dark gray or black background. Text flips to light colors. And this is where problems show up. Images with white backgrounds create a harsh contrast. Logos with transparent backgrounds can become invisible. Text overlays on light colored images become hard to read.
-
Always preview both modes
Create one mockup in light mode and one in dark mode. Compare them side by side. If your image looks great in light mode but disappears in dark mode, you need to adjust it before publishing.
-
Tips for dark mode friendly posts
Use images with colored or dark backgrounds instead of white. Add a subtle border to images so they have a clear edge in dark mode. Avoid placing light text on light colored image areas. And if your brand colors include a lot of white, consider creating a separate version of your graphics for dark mode users.
-
Why this matters for engagement
A post that looks broken in dark mode gets fewer likes and comments. People associate visual quality with content quality. If your post looks polished, they trust your message more. If it looks messy, they keep scrolling.
How Mockups Fit Into Your Content Workflow
A mockup is not just nice to have. It belongs in your content creation process. Here is where it fits for different types of creators.
-
If you post for yourself
Write your post. Paste it into the mockup tool. Check the preview on desktop and mobile. Then go to LinkedIn and publish. This adds about two minutes to your workflow and saves you from formatting disasters.
-
If you post for clients
Write the post. Create a mockup. Send the mockup to the client for approval. Once approved, publish on LinkedIn. The client sees exactly what they approved. No revision requests after the post is already live.
-
If you plan content in batches
Write five to ten posts at once. Create mockups for each one. Save them in a shared folder organized by date. When publishing day comes, you already know how each post looks. You just copy, paste, and publish.
-
If you run a content team
The writer creates the post and the mockup. The editor reviews both. The manager approves the final version. Everyone works from the same visual reference. This cuts miscommunication and speeds up the entire review process.
Types of Mockups You Can Create
Not every LinkedIn post looks the same. Each format has its own layout, dimensions, and quirks. Here are the types of mockups you can build with this tool.
- 01
Text only posts
Text posts are the simplest format on LinkedIn. But they still need a mockup. You want to check where the "see more" link cuts off your text. On LinkedIn, only the first three lines show before the fold. If your hook gets cut off, people will not click to read more. A mockup shows you exactly where the cutoff happens. So you can place your hook above the fold every time.
- 02
Image posts
Image posts get more attention in the feed than plain text. But LinkedIn crops images differently on desktop and mobile. An image that looks great on your laptop might lose its top and bottom edges on a phone screen. Use the mockup tool to check how your image displays on both devices. Make sure important text or visuals stay inside the safe zone.
- 03
Carousel posts
Carousels show up as document posts on LinkedIn. The first slide is the cover that people see in the feed. If that first slide does not grab attention, nobody swipes to slide two. Create a mockup of your carousel to check that the cover slide works. See how the slide counter looks. And preview how the swiping experience feels for your audience.
- 04
Poll posts
Polls are great for engagement. But the poll options have character limits and the layout changes depending on how many options you include. A mockup lets you see if your question and options display correctly before you publish.
- 05
Video posts
Video posts show a thumbnail in the feed before someone clicks play. That thumbnail is the first thing people see. A mockup helps you check that your thumbnail looks sharp and that the video title does not get cut off.
- 06
Article share posts
When you share a LinkedIn article or newsletter, the preview card shows a headline, description, and image. These elements often get cropped or shortened. A mockup shows you the exact preview card so you can adjust the headline or swap the featured image before sharing.
LinkedIn Post Formatting Best Practices
A great mockup starts with great content. Before you preview your post, make sure the formatting is right. These tips apply to every post type on LinkedIn.
-
Write a strong first line
Your first line is your hook. It shows up in the feed before anything else. If it does not grab attention, people scroll past. Ask a question. Share a surprising number. Make a bold claim. The first line does the heavy lifting for your entire post.
-
Use line breaks to create white space
Walls of text scare people away. Break your post into short paragraphs with one or two sentences each. Add blank lines between them. White space makes your post easier to scan on mobile. And scanning is how most people read on LinkedIn.
-
Keep sentences short and direct
Long sentences lose readers. Write like you talk. One idea per sentence. If a sentence has more than 20 words, break it into two. Simple writing performs better because more people can read and understand it quickly.
-
Place your call to action at the end
Tell people what to do after reading your post. Ask them to comment. Invite them to visit your profile. Share a link. But keep it simple. One call to action works better than three. People get confused when you ask them to do too many things at once.
-
Use emojis sparingly
A few emojis can add personality. But a post stuffed with emojis looks unprofessional. Use one or two at most. And never use emojis as bullet points. They clutter the post and distract from your message.
-
Test different post lengths
Short posts with 50 to 100 words work for quick insights. Longer posts with 500 to 1,000 words work for stories and detailed advice. Use your mockup to check how different lengths display in the feed. Find what works for your audience.
LinkedIn Post Specs and Dimensions Guide
Getting the dimensions wrong means your content gets cropped or looks blurry. Here are the specs you need for each post type.
- 01
Text post character limit
LinkedIn allows up to 3,000 characters per post. But only the first 210 characters show on mobile before the "see more" cutoff. Keep your hook short and punchy.
- 02
Image post dimensions
Use 1200 x 627 pixels for landscape images. Use 1080 x 1080 pixels for square images. Square images take up more space in the feed on mobile and tend to get more attention.
- 03
Carousel dimensions
Upload your carousel as a PDF. Use 1080 x 1080 pixels for square slides or 1080 x 1350 pixels for portrait slides. Keep the file under 10 MB for fast loading.
- 04
Video thumbnail
Use 1920 x 1080 pixels for the video thumbnail. LinkedIn auto generates thumbnails but they are often unflattering. A custom thumbnail gives you more control over that first impression.
- 05
Poll options
You can include up to four options in a LinkedIn poll. Each option has a 30 character limit. Keep your options short and clear.
- 06
Article preview card
When you share an article, the preview image should be 1200 x 627 pixels. The headline shows about 100 characters in the card preview. Write tight.
- 07
Profile picture in posts
Your profile picture appears at 48 x 48 pixels in the feed. Make sure your photo is clear and recognizable at that small size. A headshot with a clean background works best. Avoid group photos or logos that become unreadable when shrunk down.
- 08
Aspect ratio matters
LinkedIn does not treat all aspect ratios equally. Portrait images (4:5 ratio) take up more vertical space in the mobile feed. That means more screen real estate and more eyeballs on your post. Square images (1:1) are the safest choice for both desktop and mobile. Landscape images (1.91:1) look great on desktop but get smaller on phones.
Common Mistakes to Avoid
Most people make the same errors when they skip the mockup step. Here is what to watch out for.
- Publishing without checking mobile. You write your post on a laptop and it looks perfect. But 60 percent of LinkedIn users browse on their phones. Your carefully formatted post wraps differently on a smaller screen. Always check the mobile mockup before you publish.
- Ignoring the "see more" fold. Your best hook is on line four. But LinkedIn hides everything after line two or three behind "see more" on most devices. If nobody clicks that link, your hook is invisible. Place your strongest line at the very top.
- Using images with small text. You add an infographic with tiny text to your post. It looks fine on your 27 inch monitor. On a phone screen, nobody can read it. If your image includes text, make it large enough to read on a small screen.
- Forgetting about image cropping. You upload a photo and LinkedIn crops the top and bottom. The most important part of your image is now missing. Use a mockup to see how LinkedIn crops your image before you upload it.
- Skipping dark mode preview. Your beautiful white infographic looks invisible in dark mode. And about 30 percent of users have dark mode turned on. Preview both modes and make sure your visuals work in each.
- Not checking carousel cover slides. Your carousel has 10 great slides. But the first slide is generic and boring. People never swipe past it. Your mockup should focus on making that first slide a scroll stopper.
- Sending clients raw text for approval. You paste the post text in an email and ask the client to approve it. They cannot visualize the final result. Then they are surprised when the live post looks different from what they imagined. Always send a mockup instead.
- Using the same mockup for every post type. A text post looks nothing like a carousel post. And an image post looks different from a poll. If you use the wrong mockup template, the preview will mislead you. Always pick the correct post type before generating your mockup.
