Frequently Asked Questions

What is a screen resolution simulator?

It is a tool that allows you to preview a website inside a viewport with selected width and height dimensions.

Can I use a custom resolution?

Yes. You can enter a custom width and height and apply the resolution to the preview.

Why might a website not load in the simulator?

Some websites prevent themselves from being displayed inside an iframe by using security headers such as X-Frame-Options or Content-Security-Policy. This restriction is controlled by the website being loaded and cannot be bypassed by this tool.

Does this tool send my website data to FreeITTools?

No. The simulator does not upload your website content to FreeITTools. The requested URL is loaded directly by your browser.
