Website preview questions, answered.
A little more about previewing websites and what to expect.
What is a website previewer?
A website previewer lets you see how a web page looks at different screen sizes. Paste a page’s address into Online Website Previewer to compare its mobile, tablet, and desktop layouts and try the live page in your browser.
Why is a website blank?
Some websites block other pages from displaying them in a frame. Your browser respects these rules, so this tool cannot show those sites. The rules are usually set with X-Frame-Options or Content-Security-Policy. It does not necessarily mean the website is broken.
Can I click and scroll in the preview?
Yes. Each frame loads the live page, so you can follow links, open menus, scroll, and use forms. These are real interactions with the website, so submitting a form or placing an order has its usual effect.
Is it free to use?
Yes. Online Website Previewer is free, with no account required and no limit on the number of previews.
How can I preview my website on mobile from my computer?
Paste your website address into the tool above, press Preview, and choose Phone. You can also compare phone, tablet, and desktop layouts side by side. You can focus on one device, rotate the phone or tablet, and zoom in for a closer look. You don’t need developer tools or a phone to get started.
Can I check whether my website is responsive?
Yes. Compare the same page at phone, tablet, and desktop widths. Look for text cut off at the edge, images that don’t fit, and menus or buttons that are hard to reach. You can also rotate the phone and tablet previews. This is a visual check in your current browser; it doesn’t automatically score your site or replace testing on real devices and in other browsers.
Why does the phone show a desktop layout?
Some websites choose their layout using the browser type instead of the available screen width. The preview changes the viewport size, but it cannot change the browser type the website sees. Websites that adapt to screen width will respond to the different frame sizes.
Can I preview a website on localhost?
Yes, in Chrome and Firefox. Enter an address such as localhost:3000. Chrome may ask for permission to access your local network; allow it if you want to preview your local site. Safari blocks local HTTP pages inside secure pages, so use Chrome or Firefox for those.
Are preview URLs sent to your servers?
No. The address you enter is used in your browser to load the website directly. The website you preview still receives your visit and applies its own privacy policy. See our privacy statement for more details.

Preview blank or showing an error?
Many websites tell browsers not to display them inside other pages. Browsers always respect this, so those sites stay blank or show an error here, and no web page can work around it.
Some sites also choose their layout from your browser type rather than the screen size. Those can look like their desktop version in every frame.
Previewing localhost? Chrome asks once to let this site access other apps and services on your device; choose Allow. Safari blocks local http pages inside secure pages, so use Chrome or Firefox for those.
A browser extension that previews these sites too is on the way.
