Window Resizer

Resize the browser window to emulate various screen resolutions.

Window Resizer is a versatile Chrome extension designed for web designers and developers to easily resize their browser window and emulate different screen resolutions. It allows users to test how websites appear across devices by adjusting window size and position, via customizable lists of resolutions.

Key features include fully customizable resolution presets (add, delete, reorder), options to set window width, height, and position, as well as preset icons representing phone, tablet, laptop, and desktop. Users can apply size changes to the entire window or just the viewport. Additional functionality includes configurable global keyboard shortcuts, and the ability to export and import settings for easy use on multiple computers. This extension streamlines responsive design testing directly within Google Chrome.

User reviews

Window Resizer is widely praised for its ease of use, reliability, and time-saving capabilities, especially for developers and content creators. Users appreciate its custom presets, hotkeys, and multi-browser support. However, recent updates have introduced bugs causing loss of settings and resizing errors. Multi-monitor scaling issues and some UI limitations are also reported. Despite these problems, many still find it an essential and efficient tool for managing browser window sizes.
Pros
  • Very useful and reliable window resizer that enables precise resizing and repositioning with custom presets.
  • Saves significant time and effort especially for content creators and developers needing specific window dimensions.
  • Supports quick workflow by allowing easy setup of hotkeys and multiple preset sizes.
  • Simple, fast installation and intuitive user interface makes it accessible to various users.
  • Works well across different browsers like Chrome and Edge and multiple monitor setups.
Cons
  • Recent updates have caused loss of user settings and introduced bugs preventing proper resizing.
  • Some users report that resizing sometimes causes incorrect dimensions, or extension fails to work as expected after updates.
  • Issues appear when using multiple monitors with different scaling settings, leading to improper window sizes or incorrect window moving behavior.
  • Lack of multi-language support limits usability for non-English speakers.
  • Some user interface features, like hotkey management, could be more flexible and intuitive.

This is in my opinion the best window resizer for Chrome. I've been using it for several years and it does exactly what I need it to do without any issues. Fantastic! I should probably throw some money at the developer to show my appreciation...

I use this extension every single day I'm a YouTuber and I rebroadcast my screen and having it at the right dimensions is everything saves me a lot of time and energy absolutely love it if you haven't paid for the paid version I would recommend doing so

chromeとEdgeで使用しています。 ・chromeにて、マルチウィンドウでディスプレイごとの倍率が異なるときに、現在表示しているディスプレイから別のディスプレイに、表示位置・表示サイズを指定して移動すると、表示サイズが合っていない。(倍率の違いによる影響と思われる) ・Edgeにて、複数のEdgeのウィンドウを表示しているときに、表示位置・表示サイズを指定して移動しようとした際、指定したのと違うもう一つのウィンドウのほうが移動してしまうときがある。

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Window Resizer does not require any sensitive permissions.

Risk impact analysis details
    Risk likelihood
    Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

    Window Resizer has earned a good reputation and can be trusted.
