📱 Device Art Generator

What Is a Device Art Generator?

A device art generator (also called a mockup generator) places your screenshots inside realistic device frames — iPhones, Android phones, tablets, and laptops. The result is a polished, professional-looking image that shows your app, website, or design as it would appear on a real device. This technique is standard practice for app store listings, portfolio presentations, marketing materials, and client deliverables.

This tool runs entirely in your browser using the HTML5 Canvas API. Your screenshots are never uploaded to any server — the device frame rendering happens client-side, ensuring complete privacy and instant results.

Why Device Mockups Matter

A raw screenshot tells the viewer what your app looks like, but a device mockup tells a story. Research from app store optimisation (ASO) studies consistently shows that app listings with professional device mockups receive 20–30% more downloads than those with plain screenshots. The device frame provides context — it signals that this is a real, finished product running on a familiar device.

For portfolio presentations and client pitches, device mockups transform flat designs into tangible products. A website redesign shown inside a laptop frame immediately communicates "this is how it will look in the real world" in a way that a flat image cannot.

Supported Devices

App Store Screenshot Guidelines

Apple App Store (iOS)

Apple requires screenshots for every device size your app supports. The key sizes are: 6.7" display (iPhone 14 Pro Max) at 1290×2796 pixels, 6.5" display (iPhone 11 Pro Max) at 1242×2688, and 5.5" display (iPhone 8 Plus) at 1242×2208. You can submit up to 10 screenshots per localisation. Apple recommends showing core functionality in the first two screenshots, as these are visible without scrolling in search results.

Google Play Store (Android)

Google Play requires a minimum of 2 screenshots and allows up to 8 per device type (phone, 7" tablet, 10" tablet). Phone screenshots should be between 320px and 3840px on any side, with a maximum aspect ratio of 2:1. Google Play supports screenshots with device frames or without — but framed screenshots tend to perform better in conversion tests. Add short captions to highlight features.

Customization Options

• Device Colours: Black, white, gold, pink, blue, green, and custom colours. Choose a frame colour that contrasts well with your screenshot and background to make the mockup stand out.
• Background Styles: Solid colours, gradients, and transparent backgrounds. Gradients (especially dark-to-light diagonals) create depth and visual interest behind the device frame.
• Shadow Effects: Soft, hard, or no shadow with adjustable intensity. Soft shadows create a realistic floating effect. Hard shadows add a bold, graphic look.
• Orientation: Portrait and landscape modes. Use portrait for app screenshots and landscape for website or dashboard mockups.
• Scale and Position: Adjust the device size and position within the canvas. Leave padding around the edges — a mockup that bleeds to the edge looks cramped.

Best Practices for Device Mockups

• Use high-resolution screenshots: Start with the highest resolution screenshot available. Scaling down always looks better than scaling up. A blurry screenshot inside a crisp device frame looks unprofessional.
• Match the aspect ratio: The screenshot should match the device's native aspect ratio. An iPhone screenshot cropped to 16:9 will leave gaps or distort inside the frame. Use the correct screen dimensions.
• Keep status bars consistent: If your screenshot includes the device status bar (time, battery, signal), make sure it shows realistic values. A clock showing "9:41 AM" is the Apple convention for marketing screenshots.
• Show meaningful content: Display your app in a state that shows real value — a filled dashboard, a completed task, or a key feature in action. Empty states and loading screens do not sell.
• Use consistent styling: If you create multiple mockups for an app store listing, use the same background colour, shadow style, and device colour across all images. Consistency signals professionalism.

Common Use Cases

• App Store Listings: Create professional screenshots that increase download conversion rates by showing your app in realistic device frames.
• Portfolio Presentations: Showcase your design or development work in context — clients and hiring managers respond better to mockups than flat screenshots.
• Marketing and Advertising: Use device mockups in Facebook ads, Google display ads, and landing page hero sections to give potential users a preview of the product experience.
• Blog Posts and Documentation: Embed device mockups in how-to guides, feature announcements, and release notes to make technical content more visually engaging.
• Pitch Decks: When presenting a product to investors or stakeholders, device mockups transform abstract concepts into tangible product visuals.
