Social Media Mockup Tool: Preview Posts Before They Go Live

Posting creative without seeing it in context is risky. Sending a spreadsheet of copy to a client requires them to imagine the final output. Our Social Mockup Tool creates high-fidelity mockups of your social content. While no tool can guarantee a 100% pixel match due to frequent app updates, our engine maps your assets to the latest known UI standards for the latest platforms and formats.

Stop using "lorem ipsum" placeholders. This tool allows you to input your actual headlines, body copy, and creative assets to generate a high-fidelity mockup. Whether you are presenting a deck to a stakeholder or getting legal approval, a visual preview eliminates ambiguity.

Why It Matters

In modern marketing workflows, approvals happen asynchronously, and visual context matters. A post that looks fine in a doc may look awkward in-feed. This tool helps teams reduce revisions and speed up approvals by showing what the post will actually look like before publishing.

Key Features

Supported Platforms

  • LinkedIn: Preview professional updates, ensuring line breaks and "See More" truncations are accurate.
  • Instagram (Feed Post and Reels): Visualize the aesthetic of your grid and vertical formats.
  • TikTok: Check if your caption overlays will be obscured by the platform's UI (buttons, likes, shares).
  • X (Twitter): Verify link card previews and character spacing.

Why do previews look different on mobile vs. desktop?

Social platforms dynamically resize content based on the user's screen resolution and device OS. Our tool simulates the standard "Mobile View," which accounts for 80%+ of social traffic, as this is the most critical view for advertisers.

What are the best image sizes for 2026?

Vertical (4:5 or 9:16) is now dominant across LinkedIn, Instagram, and TikTok because it occupies more screen real estate. Square (1:1) is secondary, and landscape (16:9) is largely reserved for YouTube.

Can I use these mockups for client approval?

Absolutely! That is the primary use case. Sending a visual mockup reduces revision rounds by 50% compared to sending a text document. We're all about saving you time and work.

Does this tool actually post to social media?

No. This is a visualization and approval tool only. We do not connect to platform APIs to publish content, ensuring your data and accounts remain secure.
