PageSnap Devices: Mobile Simulator & Responsive Tester

See any website in a phone, tablet or desktop frame, then capture it. Every device is free. No account, nothing uploaded.

Check how a website looks on a phone, a tablet or a desktop screen without leaving your browser, then capture what you see. Click the toolbar icon and the page you're on opens inside a device frame, live. Scroll it, click around, rotate the device, or add more devices beside it. The device's measurements sit beside the frame, so you always know the size you're testing. EVERY DEVICE IS FREE More than 100 devices, from the iPhone 5 to the newest iPhones, Android phones and foldables, plus tablets, laptops, monitors, TVs, a kiosk, a smartwatch and rugged scanners. Nothing is locked behind a paid tier. Open the list with the Devices button and it stays beside the device while you try others. Search it, star your favorites, and save your own custom sizes. NO ACCOUNT, NO TRACKING, NOTHING UPLOADED There's no sign-up and no analytics, and the extension has no server. Your settings and screenshots stay on your computer. FROM SCREENSHOT TO BUG REPORT Save a PNG with a transparent background around the device, or capture just the screen. Click Annotate to send the capture straight to the PageSnap Pro editor to add arrows, numbered steps and blur, which makes it quick to write up a bug or send feedback to a client. SEVERAL DEVICES SIDE BY SIDE Put up to five devices next to each other. Click a link or type an address in one and the others follow; scroll one and the others scroll with it. One screenshot captures them all in a single image. MADE FOR RESPONSIVE TESTING • Portrait and landscape • Zoom, so large devices fit your window • See iPhones as Safari or Chrome • Touch-style scrolling and a touch cursor • Address bar and reload • Light and dark mode • Keyboard shortcuts, and "Open in PageSnap Devices" on the right-click menu • Presentation mode for client demos, with your own background colour • Copy a device's size, media query or User-Agent • Optional scrollbars for a mouse without a scroll wheel FOR DEVELOPERS Sites can check window.isPageSnapDevices to tell they're open in the simulator, for example to hide a banner. It's set before the site's own scripts run, and only inside the simulator. ONE PERMISSION PROMPT, EXPLAINED FIRST Nothing is requested at install. The first time you open a site, it asks once for access to all sites, which covers viewing and screenshots. The browser's capture feature requires this. A small script starts on each page and stops immediately unless it's inside the simulator. You can remove access any time. THIS IS A SIMULATOR, NOT A REAL DEVICE Pages run on your own browser's engine, so an iPhone frame won't show Safari-only bugs, and pages draw at your own screen's pixel density. Some sites refuse to run inside a frame or block sign-in there, and the extension tells you when that happens. Use it to check layouts and responsive behavior, and use real devices for final sign-off. The full list of differences is one click away in the app. Screenshot editing requires the separate PageSnap Pro extension (version 1.0.7 or newer). Device names are trademarks of their owners; this extension isn't affiliated with them, and its device frames are original drawings, not the makers' artwork.
