High Contrast

Description from extension meta

Change or invert the color scheme to make webpages easier to read.

Image from store High Contrast
Description from store High Contrast lets you browse the web with your choice of several high-contrast color filters designed to make it easier to read text. When you install this extension, all pages are "inverted", so black becomes white and white becomes black. Press the "browser action" icon in the toolbar to toggle it on and off, or customize your settings on a per-site basis. Use a convenient keyboard shortcut to quickly change your settings while you browse. Other extensions try to change the default colors, but this ends up breaking many popular websites. Only this extension applies filters to your page that invert almost everything - the only exception is photos, which are left alone. Also note that the Chrome web store and other built-in pages like the New Tab page and Settings pages are unaffected - extensions like this one are not allowed to modify them, by design.

  • (2021-07-16) Elias Khalil: Fantastic.Thanks Devoloper
  • (2021-05-17) l z: 别的插件没法设置黑色背景的,这个插件可以,强烈期望给个白名单网站的选项
  • (2021-04-30) Tiago Franzoni: Bom e muito prático. Porém, ao meu ver, sertia muito melhor se houve a possibilidade de, alguma forma, selecionar quais guias do Chrome a extensão High Contrast estará ativa! isso facilitaria para ativar a extensão apenas nas páginas de leitura e as demais continuariam sem alteração. #Ficaadica!
  • (2021-04-18) Harshit Tomar: Does not work for PDFs😥
  • (2021-04-09) d d: 反転グレースケールが特に目に優しく感じます。ありがたい拡張機能です。 「画像は反転しない」という選択肢が欲しいです。 今は画像を確認するために反転を解除しないといけないので。
  • (2021-04-06) Larry Sessions: I like this extension, and it does a good job of fixing a problem that should come as a built-in option for Chrome in the first place. It is a crime that web designers have made the standards to make pages harder to read, but it is something that should be fixed natively in a browser. This extension is the best fix I have found. However, for some reason I cannot it to save the defaults. I dislike the inverted colors generally, and much prefer the increased contrast option instead. I can change to that, and it works fine during a single session. But it defaults back to inverted colors as soon as a close the browser and reboot. I strongly suspect that this is a Vivaldi/Chrome or Windows issue, not the extension, but it is mildly annoying.
  • (2021-03-30) Rick Richards: Does nothing at all.
  • (2021-03-30) wonduck Goldensquirrel: 사진이나 동영상등 화면에 표시되는 항목에 대해 고대비 현상 안좋네요... 사진이나 동영상등 화면에 표시되는 일반처럼 검은색 바탕에 (흰색 또는 노란색) 표시 설정시 사진, 동영상 고대비 영향을 안줬으면 합니다.
  • (2021-03-26) alok kumar: too many bugs
  • (2021-03-25) Jo Li: I downloaded this specifically for working on text documents on Google Docs and Grammarly. When it works, it works well enough. True to its name, it makes things high-contrast, which means that even in the Inverted color scheme, stuff is brighter than it needs to be. There's one other major problem that I've found. If you load a Google Drive/Docs page in a new window and that window isn't the focus, the extension simply doesn't work. You can disable and re-enable it and you can fiddle with the settings, but nothing happens. Why do I have to keep my eyes GLUED to a webpage for it to turn dark? That kind of defeats the purpose, for me. Honestly, I'm better off just using this for Grammarly and using a bookmarklet for other stuff…
  • (2021-03-24) Bint e Riaz: Found exactly what I was looking for! :)
  • (2021-03-23) Roger T. Imai: High Contrast, along with Ctrl/+, Ctrl/-, and Ctrl/0 is a major eyesight saver for me with Wet Age-Related Macular Degeneration. I found some months ago, because Facebook changed the way it handled some images on user home pages, user profile pictures disappeared, and just today, I discovered that it was related to High Contrast. It needs to be disabled (not removed) when viewing Facebook pages, to show user profile pictures (which appears in a circle in the header background at the top of the page.) Otherwise, a great extension!
  • (2021-03-21) MollyMaster: U dont need these extentions just go to setting on ur actual computer and click high contrast EASY u dont need this stuff
  • (2021-03-02) Mitha Aulia: Membuat tampilan chrome saya sedikit berbeda. jadi tidak bosan lagi :D
  • (2021-02-18) Jodi W: It would be perfect if it worked as described, however, even though it explicitly states "photos/pictures are unaffected? every photo I have in Google Photos became an x-ray when extension is enabled
  • (2021-02-15) Nathan Maddux: You have to turn it on site by site, so you get blinded with light while you scramble to turn it on. It doesn't work on some pages.
  • (2021-02-09) Amit A: Despite the privacy implications of this extension (it's owned by Google), I like using it for the fact that I like the contrast it provides. A suggestion to make it even more useful would be to provide an option where the increased mode does not get applied to the images on the page. The contrast on the images makes it extremely difficult to read charts and other readable elements on it.
  • (2021-02-03) Hubert K: It's changing json and blocking partial after sending forms.
  • (2021-02-01) denise m: It is fine for text if you don't mind white on black but is messes up all the photos for shopping (I prefer black on white not bloody grey). Can't we get a setting that just darkens what is there?
  • (2021-01-27) Jen Ames: do not download
  • (2021-01-20) Kees Mills: Great plugin but breaks Google Docs (won't show images) and Youtube (Videos won't load). Would be nice to be able to exclude videos, images and/or sites from high contrast.
  • (2021-01-04) 橋本ヘンリー: 視野障害があってこのような拡張機能なしでは活字がほとんど読めません。大変助かっています。強いて言えば、若干困ったことがあります。1.Gmailのメッセージを印刷しようとする時に、反転したままで印刷されます。できれば原本の通りに印刷したいです。2.写真や画像も反転されるので余計に見にくいです。
  • (2021-01-03) Robert Sturgess: There are quite a few sites this extension doesn't work with and it hasn't been updated for qutie some time. The font contrast extension for firefox is far better.
  • (2020-12-20) Kiri Blakeley: didn't seem to work for me. Hit control, shift, F12 and it did nothing except change my volume. Does this not work on Macs or something?
  • (2020-12-18) Pavlik: Могут возникать приступы эпилепсии при использовании
  • (2020-12-10) Kiraz Kolukırık: Bende olmadı siz yine de deneyin yada ben mi fark edemedim belki de çok az etki gösteriyordur.
  • (2020-12-09) Wojtek B: Shift + f12...? Really...? On Chromebook...!?
  • (2020-12-08) Terry Davis: I now normally zoom in to read many sites but sometimes even then the text was too light against a white background. After installing this extension and turning on the "Increase Contrast" setting all the text is just plain simple readable black. So much better! A great extension.
  • (2020-12-03) Lev Kulgavin: It kills Facebook profile pictures
  • (2020-12-02) Kitiarian: Does not work as described, changes all or nothing but also not reliably. There is no adaptation to account for sites using coloured text either - it just makes that worse - can turn into bright pink on blue or something. Only use it because can't find a better option
  • (2020-11-28) Kali STD: Rozjaśnia jedynie wszystko, nie polecam
  • (2020-11-23) Fátima Guadalupe López Pérez: no se quitarlo ayudA aa
  • (2020-11-06) 田志浩: 再多个夜间模式选项就好了
  • (2020-10-29) Alex P: Отлично!
  • (2020-10-23) Sculpted Paint: I can't live without this readability extension yet it has made Facebook profile images disappear with their new update (Oct 2020) so you can't see who you're talking to in a thread! My profile photo has also disappeared to blank white. How to get ahold of Google to tell them this! How to read the frickin web AND see images on Facebook?? Who was the idiot that made the web unreadable in the first place and how to change it back to what WAS working to not need all these workarounds???
  • (2020-10-07) Supriya Bashetty: Most of the times its not working,Every time I select different contrast i need to refresh the page.Worst extension I have ever used.
  • (2020-10-06) Guy Shahar: Great idea, but interfered with other plugins, stopping them working - so I had to uninstall.
  • (2020-10-04) Len Kowalik: the only exception is photos, which are left alone Not true! It inverted colours in WhatsApp and in Google photos, at which point I wrote this review and removed it
  • (2020-10-01) Michael Sanft: Messes with images.
  • (2020-09-29) galaxyrizki: Burned my eyes, Plus when i went to youtube, Or any of my browser games, Everything was bright and white and blue and it made me dizzy
  • (2020-09-19) bangun waloejo: Cukup dapat mengubah tampilan di monitor screen menjadi lebih tajam untuk pengguna yang sudah uzur usianya........ Sebaiknya Menu untuk kontras lebih di buat simple pengaturannya. Tks
  • (2020-09-16) Jackson Rutner: i tried to disable it but it wouldn't now my full screen button is gone
  • (2020-09-16) Alice Freeman: I added this for migraines and light sensitivity and I can't get it to work at all, I love the concept. I could be doing something wrong or not doing at all. I also suffer from TBI's.
  • (2020-09-14) Shivian Morgan: Really like this extension, but I sincerely wish that bright-green-on-black was one of the color options. Yellow-on-black is pretty great, but not my favorite.
  • (2020-09-11) jock look: 图片显示不正常,其余还好
  • (2020-09-05) William Zhao: It used to work very well a few months ago. That is, until they started changing to program to try to not invert some parts of the screen. Now there's bugs all over the place, when I load into a webpage there's a chance I have to refresh a few times before it started inverting the colors. The site customization don't work anymore and colors get inverted even if I tell it not to... Like I'm fine with toggling it off once a while when I actually want to look at videos or photos, but I'd much more prefer the intuitive behavior that it used to have.
  • (2020-09-03) Ryo Tedeschi: doesn't really function properly anymore. half the websites i visit it doesn't kick in includng google docs. or it wont *stay* enabled and when i go to another page it's off again.
  • (2020-09-03) Ziad Krayem: Very useful and nice. And the options to visual assistance option is awesome instead of assuming one shoe fits everybody. One hopeful request: On Chromebooks, Shift+F11/F12 are reserved for adding removing desktops and cannot be overridden, so I am unable to use the shortcuts and have to do it from the extension menu every time. Please add the option to select different keyboard shortcuts. Thank you so much.
