Why do so many sites fail to preview?

Most sites set X-Frame-Options or CSP headers to prevent iframe embedding as a clickjacking defense.

Does the target site see my visit?

Yes. Loading a page in an iframe is like visiting it directly. The target site receives your IP and headers.

Can I use this to check if a site is safe?

Not reliably. Use the URL Scanner tool for safety analysis without visiting the page.

Is this better than screenshot services?

For privacy, yes. Screenshot services log every URL you submit.
