LinkedIn Post Previewer

What is a LinkedIn Post Previewer?

If you spend any time creating content on LinkedIn, you have probably noticed that what you type in the editor and what actually shows up in the feed do not always match. Line breaks can disappear, images get cropped differently than you expected, and longer posts get hidden behind a "see more" link that cuts off your opening lines. Our LinkedIn Post Previewer shows you exactly how your post will look to other people before you publish it. You get the real post card layout with your name, headline, images, and engagement counts, all updating as you type.

Think of it as a sandbox for your LinkedIn content. Type out your thoughts, upload your images, set the engagement numbers, and get an accurate preview of the finished post. No LinkedIn account needed, nothing gets published, and everything stays in your browser. If you also post on X (Twitter), check out our X Post Previewer for the same experience on that platform.

What You Can Do With This Tool

We built this to match the real LinkedIn posting experience as closely as possible. Here is what you can do:

• Upload up to 4 images. The previewer handles multi-image uploads and automatically arranges them in the correct grid layout. One image takes the full width, two go side by side, and three or four get arranged in a grid. You can remove individual images without clearing the rest.
• Set your own engagement numbers. Customize likes, comments, and reposts. This is great for building mockups, case studies, or pitch decks where you want to show what a post could look like with realistic engagement metrics.
• Customize your author info. Enter your display name and professional headline. These appear in the preview exactly like they would on your real LinkedIn profile, right above the connection badge and timestamp.
• Download as JPG. Hit the Download button to save your preview as a high-quality image file. Great for sharing mockups in Slack, adding to presentations, or keeping a record of content ideas.
• Emoji picker and polls. Add emojis directly from the built-in picker, or toggle a poll to see how voting options will look in your post. There is also a location tag option if your content mentions a specific place.
• Character limit toggle. The standard 3,000 character counter is on by default, but you can turn it off whenever you want. Some people prefer drafting freely and then trimming down later.
• Mobile view. Switch to mobile layout to see how your post looks on smaller screens. Since a lot of LinkedIn browsing happens on phones during commutes and breaks, this is a useful check before posting.

How to Use the Previewer

It takes about ten seconds to get started. Here is the quick walkthrough:

1. Enter your name and headline at the top of the compose panel. The headline is the text that appears right below your name in LinkedIn posts, usually your job title or a short professional tagline.
2. Set engagement numbers for likes, comments, reposts. They default to 10 so the preview looks realistic from the start, but change them to whatever you need.
3. Write your post in the text area. As you type, the preview updates on the right side in real time.
4. Add images with the image icon in the toolbar. You can select multiple files at once (up to 4). Each one gets its own remove button.
5. Toggle mobile/desktop view with the buttons above the preview panel to see how your post looks on different screen sizes.
6. Download or copy when everything looks right. The Download button saves the preview as a JPG, and the Copy button puts your text on the clipboard so you can paste it straight into LinkedIn.

Character Limits on LinkedIn

LinkedIn gives you 3,000 characters for a standard post. That is significantly more room than X gives you (280 characters), which means you can go deeper into a topic, share personal stories, or lay out a detailed take on something in your industry. That said, most of the best-performing LinkedIn posts are much shorter than that. The sweet spot tends to be somewhere between 150 and 1,300 characters.

One important thing to know: LinkedIn truncates longer posts behind a "see more" link after roughly the first 140 characters (about 3 lines on desktop). That means your opening lines are doing all the heavy lifting. If those first few sentences do not grab attention, most people will keep scrolling without clicking to expand. Use the previewer to check how your opening looks and where that cut-off falls.

Hashtags on LinkedIn work a little differently than on other platforms. They do count toward your character limit, and LinkedIn recommends using 3 to 5 relevant ones. The platform uses them for content discovery and topic feeds, so they can actually help the right people find your post. Just keep them relevant and do not go overboard. If you ever need to encode special characters for sharing, our Base64 encoder can handle that.

The character counter in our previewer turns amber as you approach the limit and red when you go over. If you want to draft without any restrictions, just flip the toggle switch next to the counter.

Writing LinkedIn Posts That Actually Get Engagement

LinkedIn's algorithm weighs engagement heavily, especially within the first hour after posting. Here are some patterns that tend to work well:

• Hook people in the first line. Since LinkedIn hides everything after ~140 characters behind a "see more" link, your opening has to earn the click. Lead with a bold statement, a surprising number, or a personal story that makes people curious.
• Write short paragraphs. Big blocks of text get skipped. One to two sentences per line works best. The extra whitespace makes your post feel easier to read, especially on mobile. Use our previewer to check the spacing before you post.
• Share something personal or specific. Vague advice like "always keep learning" gets ignored. Concrete stories like "I got rejected from 12 companies before landing my dream job" get shared. People connect with real experiences.
• Add images or carousels. Posts with visual content consistently get more impressions on LinkedIn. Even a simple screenshot or diagram can make your post stand out in a text-heavy feed. Test how your images look in the preview before posting.
• End with a question. Something like "Has anyone else experienced this?" or "What would you do differently?" invites comments, and comments are the strongest signal LinkedIn's algorithm uses to push a post to more people.
• Use 3 to 5 hashtags. Put them at the end of your post. They help with discovery but do not look great scattered throughout the text. Stick to ones that are specific enough to matter but popular enough to have an audience.

Who Should Use This Tool?

Anyone who posts on LinkedIn can benefit from previewing their content. But a few groups will find it particularly useful:

• Job seekers who want their LinkedIn posts to look polished and professional. First impressions count, and a well-crafted post can catch the eye of recruiters scrolling through their feed.
• Social media managers who handle LinkedIn accounts for clients. Download the preview as a JPG and share it for approval before publishing. It saves back-and-forth and prevents mistakes.
• Founders and executives building a personal brand on LinkedIn. Thought leadership posts do better when they look thoughtful. Previewing lets you check tone, formatting, and image placement before everything goes live.
• Marketers putting together campaign mockups, performance reports, or case studies. Set custom engagement numbers to visualize how a post would look with strong traction.
• Anyone who has posted something with a formatting issue and immediately regretted it. A quick preview catches line break problems, missing images, and typos before your network sees them.
