Overview

Resize your browser window so the viewport is exactly the pixel dimensions you specify.

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.
