AI that sounds like your brand, not a robot
Enter your brand’s information, tone of voice, key messages and style guide once. The AI is trained on it, so every caption and content idea reads like you wrote it.

See how your company page post renders in the LinkedIn feed — including where the text collapses behind "see more" — before you publish.

Image preview
A LinkedIn post preview tool renders your image and post text inside a mock LinkedIn feed post so you can check the image crop, the company page name and logo, and where LinkedIn truncates your text behind "see more" — roughly 140 characters on mobile and 210 on desktop.
From the makers of this free tool
This preview tool is part of Content Manager, an AI social media management platform for marketing agencies, freelancers and in-house teams. It combines a brand-trained AI copywriter, a content calendar, a client approval portal and one-click scheduling in one place.
Enter your brand’s information, tone of voice, key messages and style guide once. The AI is trained on it, so every caption and content idea reads like you wrote it.

Upload an image and add a few notes. Content Manager writes platform-ready captions tailored to that image and your brand voice, then lets you remix or edit them before you schedule.

Stuck on what to post? Generate post ideas instantly, matched to your business, the season and upcoming events. Writer’s block becomes a thing of the past.

Publish to Facebook, Instagram, LinkedIn, Twitter/X, TikTok, YouTube and Threads from one calendar. Spend less time posting and more time creating.
The client portal gives you and each client a two-way workspace that updates in real time. Share the content calendar, collect feedback and approvals, and receive the client’s own photo uploads, without losing anything in an email chain.

Every client gets a dedicated dashboard with upcoming posts, approval status, recent activity and their brand details, so you can manage more accounts with the same team.

Generate on-brand content for every client, schedule across every platform and get approvals done, all in one place.
LinkedIn truncates aggressively and inconsistently — the cut-off sits at roughly 140 characters on mobile and about 210 on desktop. A post that reads well on your laptop can lose its point entirely on a phone. Image treatment differs too: 1.91:1 renders cleanly, squares take more feed space, and logos that look fine on a website often turn to mush inside LinkedIn’s small page avatar.
Enter your company name, upload your logo, add the image and paste your post text. Select the LinkedIn tab in the preview column. Toggle Advert to check a sponsored single-image ad, then share a link to the mockup for approval.
| Recommended image | 1200 × 627 px (1.91:1) |
|---|---|
| Square image | 1200 × 1200 px (1:1) |
| Company logo | 300 × 300 px |
| Text truncation | Around 140 characters on mobile, 210 on desktop |
| Maximum post length | 3,000 characters |
| Single image ad headline | 70 characters recommended |
Roughly 140 characters on mobile and around 210 on desktop before LinkedIn collapses the rest behind a "see more" link. Write the hook and any key claim in that first line.
Use 1200 × 627 px (1.91:1) for the standard feed image or 1200 × 1200 px for a square that occupies more vertical space. Company logos should be 300 × 300 px.
Yes. Switch the Post Type toggle to Advert and the preview renders a single-image sponsored post, including the Promoted label, the headline card beneath the image and your chosen call-to-action button.
No. Your image and caption stay in your browser while you build the preview and nothing is posted to any social network. A preview is only stored on our servers if you click Share, which creates a private link you can send to a client or teammate.
Yes. The social media post preview tool is free and requires no account, no credit card and no sign-up. Nothing you upload is published anywhere. Content Manager is the paid product behind it — a social media management platform for agencies — but the preview tool works on its own.
This preview tool is a free standalone feature of Content Manager — an AI-powered platform built for marketing agencies. With a full account you can generate brand-trained captions using AI, schedule posts across every platform, manage multiple clients from a shared workspace, and get content approved through a built-in client portal. No more copy-pasting between tools.
