Frequently Asked Questions

Everything you need to know about Website Viewer

Yes, Website Viewer is 100% free with no sign-up required. Simply visit the site, paste a URL, and start previewing. There are no hidden fees, premium tiers, or usage limits.

Some websites use security headers (like X-Frame-Options or Content-Security-Policy) that prevent them from being embedded in iframes. This is a browser-level security restriction and is not something we can bypass. Most modern public websites preview just fine.

No. We do not store, log, or transmit your URLs to any server. The preview loads directly in your browser via an iframe. Your session data is stored temporarily in sessionStorage and is cleared when you close the tab.

Yes โ€” since the preview runs entirely in your browser, you can load localhost URLs or internal network addresses (e.g., http://192.168.1.x). This makes it great for testing local development builds across device viewports.

The device frames simulate standard breakpoints: Mobile uses a 375 ร— 667px viewport (iPhone SE), Tablet uses 768 ร— 1024px (iPad), and Desktop uses a full-width view. The website inside the iframe responds to these dimensions exactly as it would on a real device.

Yes! Press M for Mobile, T for Tablet, and D for Desktop to switch device views instantly. When the URL input is focused, press Enter or Ctrl + Enter to load the preview.

Absolutely. Website Viewer is fully responsive and works on any modern browser across phones, tablets, and desktops. The interface adapts so the controls and preview area remain usable on smaller screens.

Browser DevTools require you to open them manually, know the right settings, and work on one browser at a time. Website Viewer gives you instant, shareable, zero-setup device previews โ€” perfect for quickly checking URLs sent by clients or collaborators without any technical knowledge required.
