How it works
Start from scratch, pick a sample, or let AI draft one from a topic. Format with bold, italics, lists and emoji.
Switch between mobile, tablet and desktop, and light or dark LinkedIn, to see exactly where "…more" cuts in.
Use the post insights to tighten your hook, then copy the post, download a PNG, or share a preview link.
Writing tips
On mobile only about 140 characters show before "…more". Put your strongest line first.
One idea per line. Short paragraphs are easier to read on a phone.
Bold a few key words, not whole paragraphs. Styled letters are hard for screen readers.
A simple question people can answer quickly invites comments.
A few relevant hashtags at the end beat a long list.
Many creators keep external links out of the post and add them in the first comment.
→ Quick check before you post
Open the Mobile view and read only what appears before "…more". If that alone doesn't make you want to tap, rewrite the hook. The "Stronger hook" AI button can give you a few ideas.
Guide
LinkedIn's own composer gives you a plain text box, so you often find out only after publishing that your opening line was cut off, a line break vanished, or an image was cropped in a way you did not expect. A LinkedIn post preview fixes that. Write or paste your draft and you get a close copy of the LinkedIn feed on mobile, tablet and desktop, in light or dark mode, updating as you type.
It is a free LinkedIn post preview generator for creators, marketers, recruiters, founders and anyone who writes on LinkedIn more than once in a while.
The first two or three lines of a post decide whether anyone reads the rest, and the point where LinkedIn hides everything behind "…more" shifts with screen size, line breaks and emoji. That is hard to judge by eye in a text box. A preview shows exactly which words a reader sees before deciding to tap, so you can move your strongest idea to the top, trim the warm-up sentence, or add a line break that makes the hook land.
It also catches the small mistakes: a typo in the first line, a hashtag stuck to the last word, or a list that looked tidy in a document but runs together in the feed.
Visual posts behave differently from text posts. A single image fills the width of the feed, while two, three or more images are arranged in a grid that crops each one. Upload your photos and the preview arranges them the way LinkedIn does, so you can see whether a face or a chart label gets cut off before your audience does.
For document posts, upload a PDF and flip through it as a carousel, page by page, to check that your cover slide reads well at feed size and that the text on each page is large enough on a phone.
Sometimes you know what you want to say but not how to open. The optional AI assistant can write a first draft from a short topic, make a long post shorter and clearer, and offer alternative first lines when your hook feels flat. You stay in control: you review each suggestion and choose what to keep.
Use the tool as a LinkedIn post tester before anything goes out on a company page or an executive's profile. Set the name, headline and profile photo, add realistic reaction, comment and repost counts, and the preview looks like the real thing. Send a colleague or client a share link instead of passing screenshots back and forth, and once the post is approved, paste the formatted text straight into LinkedIn.
FAQ
Write or paste your draft in the editor at the top of this page and the preview updates as you type. Start with the mobile view and read only the lines above "…more", since that is all most readers see. Then check the desktop and tablet views and the dark theme, add any images or a PDF to see how they are cropped, and read the post once out loud. When it looks right, copy it and paste it into LinkedIn: your formatting and line breaks carry over.
It is a simulator that shows how your post will look in the LinkedIn feed before you publish it — including where the "…more" cut-off falls, how your formatting renders, and how images or PDF documents appear on mobile and desktop.
Yes. You can use this LinkedIn post preview free, with no sign-up, no limit on how many posts you check, and no need to connect your LinkedIn account. Your draft is saved only in your own browser, so you can close the tab and pick up later. Nothing is published until you paste it into LinkedIn yourself.
LinkedIn allows up to 3,000 characters per post, including spaces, line breaks and emoji. Bold, italic and other styled letters are special Unicode characters that usually count as 2, so the counter here counts them the same way to keep you safely under the limit.
In the feed LinkedIn shows roughly the first 3 lines — about 210 characters on desktop and around 140 on mobile, or fewer if you use line breaks early. Switch between the mobile, tablet and desktop views to see exactly what readers see before they tap "…more".
LinkedIn has no built-in text formatting. This tool converts your selected letters into Unicode look-alike characters (for example 𝗯𝗼𝗹𝗱 or 𝘪𝘵𝘢𝘭𝘪𝘤), which keep their style when you copy and paste them into LinkedIn. Use them for a few key words only: screen readers may read styled letters oddly, and they are not found by LinkedIn search.
No. When you use an AI action, the text is sent once to generate a rewrite and is not stored by this site. Everything else — formatting, previews, images and PDFs — happens entirely in your browser.
Yes. Upload one or more images to see LinkedIn-style image grids, or upload a PDF to preview it as a swipeable document (carousel) post. Files never leave your device.
No. This LinkedIn post tester runs in any modern browser on phone, tablet or desktop, and its mobile view follows the layout of the LinkedIn app's feed. You can add it to your home screen from your browser menu if you want it to open like an app.
