Question 1

How do I test my website on mobile?

Accepted Answer

Enter your website URL and select a device preset like iPhone 15 or Galaxy S24. The tool will display your site in an iframe sized to match that device viewport. You can also enter custom dimensions.

Question 2

Is this the same as Chrome DevTools device mode?

Accepted Answer

This tool provides a quick way to preview your site at specific viewport sizes without opening DevTools. It is useful for quick checks but for full debugging, Chrome DevTools offers more features like network throttling and touch simulation.

Question 3

Why does some websites not load in the preview?

Accepted Answer

Some websites block being embedded in iframes using X-Frame-Options or Content-Security-Policy headers. This is a security feature set by the website owner. Try a different site or use Chrome DevTools for those cases.
