What is a social media post mockup?

A social media post mockup is a realistic-looking simulation of how a post would appear on a platform like X/Twitter or Instagram. It mimics the actual UI — including profile information, post content, metrics, and action buttons — without requiring a real account or published post. Designers, marketers, and content creators use mockups to preview, present, or demonstrate social media content before publishing it.

Is this tool free to use?

Yes, completely free. There is no account required, no watermark on exports by default, and no usage limits. The entire tool runs in your browser — nothing is uploaded to any server.

Does this tool upload my content anywhere?

No. All processing happens entirely in your browser using client-side JavaScript. Your text, images, and generated mockup never leave your device. No data is sent to any server.

What image formats can I export?

Mockups are exported as PNG files, which support transparency and provide lossless quality. The exported image is generated at 2× or 3× screen resolution for sharp display on high-DPI screens.

Can I use the exported images commercially?

The generated mockup images are yours to use as you see fit. They are visual representations you've created using the tool. Platform UI elements are depicted in a descriptive, illustrative way consistent with how tools like this operate.

Social Media Mockup Generator is executed locally within your client browser.Processing happens entirely on your local device — your text, images, profile details, and generated mockup output are never transmitted to a remote server host. Zero data packets leave your machine during the generation, preview, or export workflow. This architecture means your work remains fully private: suitable for confidential client briefs, NDA-protected campaigns, and sensitive brand assets.

Output Verification Required

Before applying generated mockup assets to live campaigns, client submissions, or published materials, manually audit all output fields: verify display name spelling, metric formatting precision (e.g., comma separators for large numbers), image aspect ratios, typography rendering at export scale, and colour contrast against your target background. Mockup outputs reflect the input data as provided — they do not auto-correct formatting or validate real-world accuracy.
