Transform App Screenshots into Stunning Marketing Assets
In digital marketing, presentation is everything. When you launch a mobile app or a SaaS website, displaying raw screenshots can look amateur and fail to grab user attention. Our **Device Mockup Generator** provides a professional, instant, and entirely free solution. Place your app screenshots inside sleek, realistic physical frames like an iPhone, MacBook, or iPad Pro. Customize gorgeous ambient background gradients, position offsets, and tilts to construct high-quality, conversion-optimized visuals for App Store listings, social media posts, blog headers, and GitHub documentation.
How to Use the Device Mockup Generator:
Creating polished mockups takes less than 30 seconds. Follow these easy steps:
- Upload your screenshot: Drag and drop your image into the source box, browse from your local folder, or simply press Ctrl+V anywhere to paste an image straight from your clipboard.
- Choose your device model: Toggle between iPhone 15 Pro, Samsung S24, MacBook, iPad, or standard desktop monitor frames. Select device colors and orient frames to fit portrait or landscape views.
- Refine the layout: Adjust scale, rotate the device for a dynamic 3D-angled look, and offset the horizontal/vertical position to create stunning asymmetric compositions.
- Apply background color gradients: Click one of our beautifully curated background gradients, input a custom Hex color, or check "Transparent" to output mockups that fit anywhere.
- Download or copy: Export your completed graphic in pristine, high-resolution PNG format, download as JPEG, or copy the image directly to your clipboard to paste in Figma, Google Slides, or WhatsApp!

Like all utilities on ToolShelf, the Device Mockup Generator runs 100% locally on your computer. Your screenshots, graphics, and backgrounds are processed directly inside your browser cache.
