Responsive Check
Preview how any website renders across common mobile, tablet, and desktop viewport sizes.
About Responsive Check
Responsive Check lets you preview any website at common device viewport sizes — from small phones to large desktops — so you can quickly verify that a design adapts correctly across screens. Switch between presets, rotate between portrait and landscape, and see the exact pixel dimensions being rendered.
Key Features
- Multiple Device Presets: Mobile, tablet, laptop, and desktop viewport sizes.
- Portrait & Landscape: Rotate the frame to test both orientations.
- Accurate Dimensions: Each preview renders at true device width and height, scaled to fit.
- Instant Preview: Load a URL and switch devices without reloading.
How to Use
- Enter a website URL and click Load.
- Pick a device preset to preview that viewport.
- Use Rotate to toggle between portrait and landscape.
Note on Embedding
Some sites (such as Google and many banks) prevent being displayed inside a frame using X-Frame-Options or Content-Security-Policy headers, and may appear blank in the preview.
