Responsive Website Preview Tool

The Responsive Website Preview Tool lets you instantly see how any webpage appears on different screen sizes, from iPhones and Androids to iPads, laptops, and large desktop monitors. Just enter a URL, choose a device preset, and preview how your website responds across real-world viewports without needing external browser extensions.

Unlike bulky browser DevTools, this tool is fast, visual, and distraction-free. It gives marketers, designers, and developers an immediate, true-ratio preview of how their websites adapt to mobile, tablet, and desktop screens, all within an elegant, on-page interface proprietarily built by The Brand Amp.

Yes! That’s one of the tool’s best features. You can view any desktop site in full landscape orientation even on mobile devices. The preview keeps real CSS breakpoints intact, so you’re seeing the true desktop version — not a stretched or simulated one.

The preview includes the most popular viewport sizes, such as iPhone 14 (390×844), Pixel 7 (412×915), iPad (768×1024), MacBook 13” (1366×768), Full HD (1920×1080), and QHD 27” (2560×1440). You can rotate, zoom, or fit the preview to container width for precise layout checks. Have another requested size in mind? Let us know!
