Resize the browser window to emulate various screen resolutions.

Image from store Window Resizer
Description from store This extension re-sizes the browser's window in order to emulate various resolutions. It is particularly useful for web designers and developers by helping them test their layouts on different browser resolutions. The resolutions list is completely customizable (add/delete/re-order). You can set the window's width/height, window's position, preset icon (phone, tablet, laptop, desktop) and even the option to apply the new dimensions to the entire window or just to the viewport. The extension also features customizable global key shortcuts, an option to export your settings and import them on another computer and more! Please report all bugs (or suggestions) using the support link on the extension's details page.

  • (2024-01-11) Josh Lee: GREAT TOOL, NICE FEATURES! Holy cow this thing may seem too advanced, I just wanted a single button that toggled from full screen to small, so I can see behind it, but once you play with the settings for about 5-10 minutes, you can make it do exactly what you want, just because it is so flexible. Tiny complaint: The ONE feature I don't like is HOW the hotkeys are set (hotkey for presets 1, 2,3) what if you change the order of the presets? And why when I am managing the presets, and right click one, can I not change the hotkey from there?
  • (2023-10-27) Sean S: Did exactly what I wanted. I'm not a web developer so I have on interest in the preset screen sizes but I DO want my windows in Windows placed exactly on my screen, and this can do that. However, it takes some fiddling because windows in Windows don't actually start at 0,0. More like -7,0 (for M$ Edge) and must be sized to 1934,1087 to take up the full screen. And, once you have manually sized the window to your wishes, this tool can capture that size into a preset. 👨‍🍳💋
  • (2023-08-02) Tuukka Rekonen: This used to work, but now after latest updates as i used after a while it does not work at all. Just makes incorrect sizes of my presets and shows small red note that chrome could not resize. This used to be good and worked, but now not even worth one start as sizes not able to match. Going to remove this and install another or use my very old separate html/javascript method. Maybe this was made in order to sell Pro version, but no thanks.
  • (2023-07-31) 神愛世人(神崎大帝): nice very userful
  • (2023-06-10) Eric B: Most buggy extension I've ever downloaded. None of the dimensions are actually correct if you verify them against other web tools that actually work.
  • (2023-06-07) Crystal Wang: Love it!
  • (2023-06-01) A U: doesn't work in chrome on mac
  • (2023-05-11) mino: 사용자 프리셋과 리사이즈 타겟 Viewport이 매우 편리합니다.
  • (2023-05-11) วิโรจน์ ดําชุม: Interesting but when we resize the pop-up does not appear.
  • (2023-04-05) Михаил Селюк: При разработке появилась нужда переключаться между UltraWide 3440x1440 на FullHD. Внезапно - верстка едет при реальном FullHD, и не едет при нативном (переключении в системе на FHD). Это расширение решило проблему. Спасибо.
  • (2023-03-15) Dylan Souza: works as intended. Mobile layout is perfect.
  • (2023-02-24) ‫صالح الزهراني (همس التواصل)‬‎: good
  • (2023-02-13) Margot Gabel: Super useful but could be redesigned 😅
  • (2023-01-27) EZMIL: If you're a web designer or developer looking for a way to test your layouts on different screen resolutions, look no further! This extension is like a magic wand for your browser window. You can resize it to mimic all sorts of different devices, from phones to laptops to massive desktop monitors. And the best part? You get to customize the whole thing to your heart's content. Add, delete, and reorder resolutions like a boss. And if you're feeling fancy, you can even set the window's position and choose a fancy preset icon. But wait, there's more! You can export your settings and import them on another computer, and even customize global key shortcuts. The only downside is that their latest update wasn't as user-friendly as they promised, but hopefully, they'll fix it soon. But overall, this extension is a lifesaver for anyone in the web design game
  • (2023-01-20) Simon Gibbard: Best one I've found. Perfect for recording browser-based training / sales videos. In fact, indispensable. Thanks.
  • (2022-11-16) EucliffeFT: I've been looking for this
  • (2022-10-25) Terry Tsang: Can it be resized to a resolution higher than my display? For example, 4K on a Full HD display, so that I can screen around the display area?
  • (2022-09-17) Addison Williams: Useful tool. Love it!
  • (2022-09-03) Colin S: Resizing viewport works on Chrome but not on Edge.
  • (2022-06-30) Nanako Mizuki: マルウェアを含んでいます。 この拡張機能をインストール、有効化していると検索エンジンが勝手にBingに変わってしまいます。 アンインストールして再起動すると発生しなくなるので、この拡張機能が原因です。 過去にもこの拡張機能はマルウェアを含んでいたことがありました。わざとですか?
  • (2022-05-23) Sergio López: Es todo lo que puedes necesitar si quieres una extensión de windows resizing, los que dicen que necesitan más opciones, no entiendo que podrías pedir extra.
  • (2022-05-02) Mike Knebel: Seems work very well, and easy to use! Thanks!!!
  • (2022-02-20) 비숑: 편리함 마우스드래그로 맞추는거도 힘들고한데 이건 간단~!!!
  • (2022-01-27) かみかつき: Nice! Wonderful design! Very easy to use.
  • (2022-01-10) Sebastian: Works perfect, thank you!
  • (2021-12-14) Randy Henry: Must have extension if you have a 4K monitor, or multiple different sized monitors. To be able to create custom window sizes and have them available at a click is a game changer for productivity!
  • (2021-12-13) Larry: Perfect
  • (2021-12-01) Jahm Alissa: Doesn't work on mobile sizes below the width of 500px.
  • (2021-11-21) Evan Clark: Works perfect and the hotkeys are great! The bad reviews are from people who misunderstand what it's supposed to do.
  • (2021-11-11) Akshay: Perfect!. I wanted to have a tab always open on the right side of my screen that is narrower as per my requirement. This extension does exactly what I needed. 🙌
  • (2021-09-21) Dave Ghidiu: So easy to use and increases my productivity. I love it. Hotkey configurations is awesome and the window locations remember which monitor (if you have more than one screen) the window show go to.
  • (2021-08-09) jig eye: love
  • (2021-05-24) Gabrielle Zapun: Best resizer out there!
  • (2021-05-23) Marcus Casagrande: I'm running on a 4K monitor. And after clicking on 1920x1080 option, for example, it should make the window go about 1/4 the monitor size with its content. But it's definitely not what's happening here. It's just setting the window size to windowed mode and occupying like more than 3/4 of my monitor, which is definitely not what I was expecting here.. so... Unless someone explian me what I got wrong here, the app note is the lowest possible for now, for me.
  • (2021-05-10) Mykol Harper: Would be cool if it allowed you to resize the window to the selected resolution excluding chrome's top bar ( tabs, bookmarks, and url )
  • (2021-04-28) jstamm: The sizes are all over the place. Selecting a preset size is way off the advertised sizes. The only one that is accurate is 1024x768. The 1440x900 preset results in 1424x780, 1680x1050 results in 1664x930, 1920x1080 results in 1904x960, and 2560x1440 results in 2544x1320
  • (2021-04-27) Ricsi Bohóc: Tökéletesen működik! 4 monitorom van. Azt is be lehet állítani, hogy az ablak több monitort is átérjen. Akár mind a négyet. Nagy táblázatnál, zene/video vágásnál ez nagyon hasznos! A kezdő pozíciót is menti, nem csak a méretet, tehát azt is megjegyzi, hogy melyik monitoron legyen az ablak eleje. Több különböző méretet is menthetsz előre. Nem kell magadnak megkeresni, hogy a kedvenc ablakbeállításod hol kezdődik és mekkora a mérete, csak állíts be az ablakot ahogy kényelmes, kattints az "current"-re és kész! A pro verziónak nem sok az előnye, mert mindent megkapsz anélkül is, ami kell, így azonnal meghívtam a készítőt a 4 dolláros italra! :)
  • (2021-03-23) Jacky Chou: it's very useful for web developing!
  • (2021-03-21) Mário Lins: A melhor extensão! Facilita muito a visualização do comportamento das páginas que você está criando e testando. Basta pressionar Ctrl + Shift + W e o número da opção que você quer aplicar. Simples e funcional.
  • (2021-02-20) BIOS-Pherecydes: Does what I need it to, exactly how I want it to.
  • (2021-02-05) Jainulabudeen M: Awesome
  • (2021-02-03) Jose Luis Romero: I couldn't find a way to see the current size of the screen, or if I drag it to change it
  • (2021-01-08) Alan A: wrong sizes...pls fix thx....
  • (2020-11-17) Danny Wood: Part of my workflow for years now - love the plugin, simple and gets the job done
  • (2020-11-14) Sylvio: Functional and useful!

  • (2020-08-19) Akhil Yeddula: Fantastic and must have for testing responsive websites.
  • (2020-08-19) Nirob Sheikh: Nice plugin
  • (2020-08-03) Leonardo Lica: Just Works. :)
  • (2020-07-20) ミルシア: とっても役に立っています! ブラウザを切り替えても幅までは変わらないので、スマホサイトのスクリーンショットが欲しい時はあきらめていましたが、このソフトのおかげで、スマホサイズの幅でスクリーンショットを保存できます! 寄付方法が英語でわからないのですが…有料でも欲しいソフトです。

  • (2021-12-17, v: Incorrect Size
    I have two monitors (A & B) with different resolutions. I have two pre-define sizes, one for each monitor. I have a pre-define size for monitor A. If my browser is in monitor A, selecting the pre-define size for monitor A works perfectly. But if my browser is in monitor B, and I select the pre-define size for monitor A, it does not work. It will move my browser onto monitor A (great), but the size is wrong (because the two monitors have different resolution). I think it does the re-size and then move. It should do the move and then resize.

    I have a Macbook Pro usually used with a 27" monitor. Whenever i select the dropdown to pick a preset (on my monitor view) it resizes but very frequently not to the correct size. I then have to open the resizer settings, do it again and then it changes to the correct size. Why would that be?
