Google Resizer – A Browser Extension

Google Resizer is a browser extension that displays a preview of your page at different breakpoints. It’s useful for designing websites.

The extension has a built-in offline preview mode. This mode doesn’t require any data, and it can be used in cases where there is no data available (ie. offline, development, testing, etc).

The extension is built using Google Chrome’s WebRequest API, which means that it works even with localhost URLs, perfect for development locally.

The extension was created by Google.

If you’re thinking that it might slow down your browsing, don’t worry, this is not the case!
