Description from store

Viewport Resizer lets you set your browser window to exact pixel dimensions with one click — no calculator needed.

Type any width and height, pick from built-in presets (Responsive, Tailwind breakpoints, Social & Store sizes), or save your own custom sizes for reuse. The panel floats over any page and stays out of your way.

Useful for:
• Designers and developers checking layouts at specific breakpoints
• Taking screenshots at exact dimensions for the Chrome Web Store, social media, or client deliverables
• Testing responsive designs without DevTools

Works on any http/https page. Light and dark themes included.
