Viewport Resizer — Instantly Resize Your Browser Window to Any Screen Size
Viewport Resizer is a lightweight, fast, and privacy-friendly Chrome extension that lets web developers, designers, and QA testers resize their browser window to popular desktop and laptop screen resolutions with a single click. Stop guessing, stop dragging, and stop doing mental math with window dimensions. Just click a preset and your browser window snaps to the exact resolution you need.
Whether you are building a responsive website, debugging CSS media queries, testing a web application across different screen sizes, or preparing screenshots at specific resolutions, Viewport Resizer gives you instant access to the most commonly used desktop and laptop viewport sizes — all from a clean, minimal popup interface.

WHY VIEWPORT RESIZER?
Responsive web design is the standard for modern web development. Every website, web app, and landing page needs to look great on a wide range of screen sizes. But testing responsive layouts is tedious. Chrome DevTools device mode is powerful but slow to toggle. Manually dragging the browser window edge is imprecise. And remembering the exact pixel dimensions of popular screens? Nobody has time for that.
