💡 Tips & Common Pitfalls
- Sites that forbid embedding in a frame will not load. Use Open in New Tab for those.
- This shows the layout at that width, but it is not a real device, so check touch, fonts and performance on actual hardware.
- Localhost addresses work because the page loads in your own browser.
❓ Frequently Asked Questions
Why can't I screenshot directly in the tool?
Due to browser security restrictions (CORS), JavaScript cannot capture screenshots of external websites loaded in iframes. However, your browser's built-in screenshot tools work perfectly!
Some websites don't load. Why?
Some websites block iframe embedding using X-Frame-Options headers for security. Click "Open in New Tab" to view these sites directly.
What's the rotate device button for?
It switches between portrait and landscape orientations - perfect for testing how mobile and tablet sites look in both orientations!
Can I test my localhost websites?
Yes! Just enter your localhost URL (e.g., http://localhost:3000) and it will work perfectly.
