Window Resizer

With Window Resizer, you can quickly resize the Chrome browser window to any pre-defined resolution. The extension ships with a list of pre-defined standard screen resolutions but you can easily add your own custom sizes as well through the Options window.

Web developers and designers will find Window Resizer particularly useful as the extension will help them test website layouts on different browser resolutions.

It is important to note that the Chrome extension adjusts your window size and not the browser’s viewport size so it may not be the perfect tool for testing your responsive designs.
