What Is a Device Mockup Generator?
A device mockup generator places your screenshots, designs, or artwork into realistic device frames — iPhones, iPads, MacBooks, Android phones, browser windows, and more. The result is a professional presentation image that shows your work in context, exactly as users would see it on a real device.
Mockups are essential for app store listings, portfolio presentations, pitch decks, landing pages, social media posts, and client deliverables. This tool generates them instantly in your browser — no Photoshop templates, no stock photo subscriptions, no design software required.
How to Use This Tool
- Upload your screenshot or design — Select an image that represents your app screen, website, or design. The tool automatically fits it into the selected device frame.
- Choose a device frame — Pick from available frames — iPhone, iPad, MacBook, Android phone, browser window, and more. Each frame is pixel-accurate to the real device proportions.
- Customize the presentation — Adjust background color, add shadows, change the device color variant (Space Gray, Silver, etc.), and rotate the angle to match your presentation style.
- Export the mockup — Download the final mockup as a high-resolution PNG ready for your portfolio, app store listing, or marketing materials.
Tips and Best Practices
- → Match the screenshot resolution to the device. An iPhone 15 Pro screenshot should be 1179×2556px for a pixel-perfect fit. Mismatched resolutions will be stretched or cropped to fit the frame.
- → Use consistent device frames across your portfolio. Mixing an iPhone for one project and a browser for another creates visual inconsistency. Pick one or two device types and use them throughout a presentation.
- → Pair mockups with our Social Card Debugger. After creating your mockup, use it as your OG image and test how it renders when shared on Twitter, LinkedIn, and Slack.
- → Choose backgrounds that do not compete with your design. Solid dark or light backgrounds let the device frame and your screenshot take center stage. Avoid busy patterns.
