Three simple steps to test any website's mobile friendliness.
Paste any public website URL into the input field and hit Check. Works with any live website — your own or a competitor's.
Select from Phone, Tablet, or Desktop — then pick a specific device like iPhone 14, Galaxy S23, or Pixel 7. Switch between Portrait and Landscape mode, and adjust zoom level to 50%, 75%, or 100%.
Your website loads in real device dimensions — right inside your browser. No app download, no wait time. See the exact mobile experience your visitors get.
Everything you need to test and analyze mobile responsiveness in one place.
Test your website across Phone, Tablet, and Desktop — all in one tool. Switch between device categories instantly without reloading the page.
Preview in exact dimensions of iPhone SE, iPhone 14, iPhone 14 Pro Max, Galaxy S23, and Pixel 7. No guesswork — see pixel-perfect how your site actually appears.
Toggle between Portrait and Landscape orientation with one click. Catch layout breaks and overflow issues that only appear in horizontal view.
Scale your preview to 50%, 75%, or 100% for a closer or wider look. Perfect for inspecting small UI elements, buttons, and text readability on mobile.
No installation, no extension, no account required — works directly in your browser. Enter a URL and your preview loads in seconds, completely free.
Your URL is fetched for preview only — no data is stored or tracked. Use it as many times as you want, for any website, without any cost.
Mobile is no longer optional — it's how the majority of your audience finds you. Google uses mobile-first indexing, meaning it crawls and ranks your site based on its mobile version first. A poor mobile experience directly hurts your SEO rankings, bounce rate, and conversions.
