PocketView - Responsive Design Simulator

Preview websites on phone, tablet, and laptop screens. Runs 100% locally — no account or cloud required.

Preview, compare, and test how your website looks on real devices — all without leaving your browser tab. PocketView wraps any web page in an accurate device frame so you can instantly see how it behaves on phones, tablets, and laptops of different sizes. No DevTools panel to squint at, no separate app to open, no account to create. WHAT YOU CAN DO 📱 Preview on 40+ real devices Choose from an extensive, regularly-updated catalog of real-world phones, tablets, and laptops — iPhone SE through 16 Pro Max, Galaxy S24 Ultra, Pixel 8, iPad Pro, MacBook Air, and more — each with accurate viewport dimensions. Need something specific? Enter any custom width and height. 🔄 Rotate instantly Switch between portrait and landscape with a smooth, animated flip — see exactly how your layout responds to orientation changes. 📊 Compare multiple devices side by side Select any combination of devices from the list and view them all at once, scaled to their true relative size, so you can spot layout issues across screen sizes in a single glance. 📸 Pixel-perfect screenshots Capture a screenshot of any device at its real screen resolution — not a blurry downscaled crop. Perfect for design QA, bug reports, or client handoff. 📦 Batch export to ZIP Select several devices and download screenshots of all of them at once, bundled into a single ZIP file — no more clicking "save" five times. 🌗 Light & dark themes Match your workflow with a clean dark or light interface. 🌍 52 languages The interface is fully translated into 52 languages and automatically follows your browser's language. 🔒 100% private, zero setup PocketView runs entirely on your device. There's no account, no sign-in, no cloud sync, and no data ever leaves your browser. Install it and start testing immediately. HOW IT WORKS Right-click any page and choose "Preview with PocketView," or click the toolbar icon and pick a device to jump straight into the simulator. Type or paste any URL, pick a device from the sidebar (or search for one), and your site loads inside an accurate, resizable device frame. WHO IT'S FOR Whether you're a front-end developer checking a responsive breakpoint, a designer reviewing a handoff, a QA tester verifying layouts, or a marketer previewing an email landing page — PocketView gives you a fast, accurate, distraction-free way to see your site the way your users will. No trial. No premium tier. No ads. Just a fast, private device simulator that lives in your toolbar.
