Image from store A+ FontSize Changer
Description from store A+ FontSize Changer is a Chrome Extension and Edge Chromium add-on that lets the user customize the font text size, font text color, background color and font family on a page. It actually changes the fontSize of each element unlike Chrome's action with CTRL+ and CTRL- which zooms the page. Sometimes you wish to increase the text size without zooming the page so that paragraphs do not scroll past the edge of the screen. A+ FontSize Changer works where others fail! Even on pages with dynamic (ajax) content! Even on pages with iFrames! Just use the buttons to change the fontsize or use keyboard shortcuts ALT+ and ALT- ( or use ALT+Up Arrow and ALT+Down Arrow. You can change these hotkeys at chrome://extensions/shortcuts ) Some website authors use a gray text color instead of black which can be hard on the eyes. With A+ FontSize Changer you can also change the text color and background color on a page. With this feature you can also create your own custom Night Mode where you choose the text color and background color yourself and it does not invert image or video colors so that they are still viewable. NOTES: If ALT+ and ALT- are not working on a website then try these steps: 1. Reload the website (F5 key) or restart Chrome or Edge. 2. Click on a blank space on the website page before using the ALT+ or ALT- key. 3. Extensions are not allowed to work at Chrome Web Store, Edge Add-ons store or a chrome:// or edge:// page or the new tab page. The extension popup will display a red notice with "NOTE:" if you are on one of those pages. 4. If the website has disabled keyboard keys then click on the extension icon in the toolbar and use the buttons there. 5. If ALT+Up Arrow and ALT+Down Arrow are not working then see if they are active on the extension at chrome://extensions/shortcuts PRO FEATURES: * Create profiles to save text settings and color schemes. * Saves custom font type for each website you visit * Saves custom text size for each website you visit * Saves custom text color for each website you visit * Saves custom background color for each website you visit VERSION HISTORY 12/25/2022 - Version 1.5.1 + Added "Blacklist" for locked profiles so that users can add websites that will not be changed by the profile that is checked. + Grammar correction: from "it's" to "its". + Fixed bug of font-family not loading a profile with "Load" button until page was reloaded. 8/20/2022 - Version 1.5.0 + Updated to Manifest V3 + Checked (or locked) profiles no longer save the values to each website so that you can uncheck the profile and those websites will default to normal. 8/19/2022 - Version 1.4.9 + Performance improvements + Extension badge now displays if the user has changed the font color, background-color, font-family or as usual the font-size multiplier for a website. 1/10/2022 - Version 1.4.8 - Corrected some German spelling. 1/10/2022 - Version 1.4.7 - Added Portuguese language. (Português) 1/6/2022 - Version 1.4.6 - Added Chinese Traditional (zh-TW) and Chinese Simplified (zh-CN). 9/7/2021 - Version 1.4.4 - Fixed some license issues. No longer puts gray translucent background under Youtube video controls. 4/7/2021 - Version 1.4.3 - Cosmetic changes. Changed buttons and input fields to use font-family: Consolas, monospace. Changed footer background color. Added German language. 4/7/2021 - Version 1.4.3 - Cosmetic changes. Changed buttons and input fields to use font-family: Consolas, monospace. Changed footer background color. Added German language. 3/4/2021 - Version 1.4.2 - Now displays a notice if the user did not allow the extension to use the user's email address to check for license status from servers. Hopefully fixed it so that text size does not get larger than set size on some websites on page refresh because of slow loading external stylesheets or dynamic content. It will not work in all cases, otherwise the extension would have to be delayed for 10 seconds or more on some websites with many external resources. 2/16/2021 - Version 1.4.1 - Fixed a bug where the extension would not work when first installed on websites that were already open in the browser. Now it will work on a fresh install without refreshing the page. Also added better support for Edge Chromium browsers. 2/11/2021 - Version 1.4.0 - Fixed a bug in the license status check. It will now display an error message if the user did not approve access for the extension to check license status or if the user is not signed into Chrome and therefore the license status cannot be checked. 2/10/2021 - Version 1.3.9 - Fixed a bug from version 1.3.7 where backgrounds with url images with partial transparency would get a partial transparent background so that some video players like jw-player would not get the video blocked out. But the fix was being applied to the body tag as well. Fixed so that the body tag will always get a solid color and no transparency. Also added more error checking to license status check. 2/2/2021 - Version 1.3.8 - Added a filter to lower the brightness on page load for users that set the background-color to black or a dark color to try and prevent the original white background from showing. Unfortunately, it only works well some of the time. But the original white background is less bright more quickly than before. Also fixed a bug where Pro users that already paid were not getting the correct license. 1/31/2021 - Version 1.3.7 - A number of performance improvements. It should use less resources now. Added Dark Mode support for the A+ popup. Added colors for hyperlinks including visited hyperlinks being a different color! Also boxes and buttons that do not have a default white background will now have a slightly different color than the color chosen by the user so that boxes and buttons are easier to identify. Version 1.3.5 was not converting background colors for elements with full transparency but was still converting elements with partial transparency. Now it will convert colors but with the transparency value also saved with the conversion. Hopefully this will help some video players like jw-player controls that use alpha to display correctly. Also elements with IMG or background-image with url images will have a slightly different color background. This helps if the image has a transparent background and a dark icon such as icons and the user has selected a black background color. IMPORTANT UPDATE: Chrome Web Store Payments in being deprecated by Google, therefore this update has a new permission to read a user's email address to process license information for both old Chrome Web Store payments and the new payments processor. 5/22/2020 - Version 1.3.6 - It seems that font changes and color changes were not working in iFrames since about version 1.2.5. This has been fixed. Previously, font size changes were only working if the user clicked on the iFrame first and used ALT+ or ALT- to change the size. Now pressing ALT+ ALT- and ALT-Backspace on the main page will change the text size for both the main document and iFrames without having to click on the iFrames first. Known Issue: Some iFrames with content like Disqus comments may have a problem loading saved settings correctly because of the delayed way that Disqus loads content and css. Text may get too large and crowded (line-height). This may also cause "Reset Colors" to not reset the iFrame without refreshing the webpage (F5 key). Now removes the default font from saving if reverting back to the default font on the page. 4/18/2020 - Version 1.3.5 - It now does not change the background color of elements that have a transparent background so that they can still be seen through. Also if the background-image is a gradient instead of a url then it will set the background-image to "none". 9/24/2018 - Version 1.3.4 - Added Languages in pop up. 4/16/2018 - Version 1.3.3 - Added "user-select:none" to css of the buttons in the popup. 4/6/2018 - Version 1.3.2 - Now you can use ALT+Up Arrow and ALT+Down Arrow to change text size. You can also change these hotkeys at chrome://extensions/shortcuts 3/30/2018 - Version 1.3.1 - Removed trying to make it work with Google's new tab page. With apologies it was not realized that there is no way to tell the difference between chrome://newtab and extensions that created their own new tab. 3/22/2018 - Version 1.3.0 - Lite and Pro Edition - Now the Lite Edition also changes font size by .1 increments instead of .2 increments, just like Pro. Also fixed in Lite Edition the contentEditable bug that would change size when the user changes to bold or italics. Bug Fix: Keeps the current page view scroll position in the same place after a font size adjustment for most pages by calculating the position before the change and then setting the scroll position after the change. This version also shows the color picker and the text input for color hex values, so you can manually enter hex colors or use the color picker. Also new setting added "Underline Links". So users can choose if links are underlined or not when the color is changed. The default is to "Underline Links" because on most websites it would be difficult to see the links when they are the same color as the rest of the text on the page. But some users prefer not to have links underlined. Also now line-height is adjusted if line-height is too small after a text size change. 3/21/2018 - Version 1.2.9 - Pro Edition and Version 1.2.5 - Lite Edition - Now using the custom color picker instead of the HTML 5 color picker because now some Windows users were having the same bug that Mac OS users were having of the HTML 5 color picker window opening and the extension popup closing. Using the custom color picker fixes that bug. 5/8/2017 - Version 1.2.4 - In the Pro edition you can now change the font type (font-family) for each website you visit and the font family will be saved. 4/20/2017 - Version 1.2.3 - Added note in extension popup that explains that extensions do not work in special chrome:// pages or at the Chrome web store. 4/12/2017 - 1.2.2 - Bug Fix for Mac OS X. I believe I have fixed the bug that some Mac users are experiencing of not being able to change the color. Apparently Chrome extensions have a bug with Mac OS using the HTML 5 color picker where when the color picker opens the extension popup closes causing the popup to not recognize the color commands. Now using a different color picker for Mac users. 4/9/2017 - 1.2.1 - Added change event to color picker to see if it would fix the problem for some users not able to get the text color or background color to change. 9/12/2016 - 1.2 - Now you may not have to reload the current page when you first install this extension or if you disable it and re-enable it. 08/12/2015 - 1.1 - Fixed alert "ERROR: Could not establish connection." when clicking on A+ icon when the extension is first installed. Now it tells the user to refresh the page. 08/12/2015 - 1.0 - A+ FontSize Changer created

  • (2023-11-09) Александр: На каждой страницы одного сайта надо настраивать заново. И если перезагрузил страницу - тоже. Бред.
  • (2023-09-15) Ellie T: Very easy to use. Helps my eye out a lot, especially as my screen is not set up close to my chair. Thank you for this.
  • (2023-08-13) Jason Fuhrmann: Excellent! Works great. Being able to change not only the font size, but font color and background color is a lifesaver! Makes reading much more easy and enjoyable!
  • (2023-06-24) Rachel Hagan: Shockingly hard to find a "darkroom" theme or extension (red text on black screen), which is sometimes all my eyes can handle. This app fixed THAT problem AND more...My eyes thank you...
  • (2023-06-08) Diane Hofstetter: I turned 76 years old this week. Thank you for making me feel young - or at least capable - again.
  • (2023-04-30) Scy master (Scymaster): neat, increase font size as prefered for each page without much effords
  • (2023-02-10) Pat MySecret: Perfect! The stock chart side numbers were too tough to read.. This sizes them up right! Will also change Font and background color.. upgrade saves it to site.
  • (2023-02-09) Chris Vydas: Trial for font size?! Oh wow.
  • (2023-02-03) Daniel Rem.: Doesn't save my settings,after every refresh it resets to white background. No option for free use,money hungry extension.
  • (2023-01-30) Dean Gladish: I loved it. How is this interactive with GMail and to what extent?
  • (2022-08-07) Rocky Nelson: This extension slows down my Facebook browsing to almost un-usable annoyance. In addition, it scrambles my email server from fastmail.com. I submitted a service ticket and the tech who investigated my problems recommended getting rid of my Chrome Extensions one by one to see what happens. I turned off A+, rebooted Chrome, and my email problems were solved, as well as being able to use Facebook again. I want my money back! This extension might have worked a decade ago, but it warps current software. Background colors change back and forth as I switch tabs. Background colors flicker as I open links. I am sorry that I spent $10 to find out .. I was offered to buy the "PRO" version, but the Chrome store link sold me "LITE".. I have no idea if there is a pro version at all. I am pleased that I can use Ariel Black for my default font, but I could have done that with other extensions for free.
  • (2022-06-26) Mohamad Issa: it was good until i paid for the pro version... now its not working properly!!!!
  • (2022-06-11) John Pen: its just zooming in and out absolute garbage
  • (2022-04-26) Andrea Segantini: Just started using this extension, saved my eyes a bit of stress and saints from my rage
  • (2022-03-16) T N: It doesn't save the settings after refreshing the page.
  • (2022-01-04) JACKY CHERNG: 為什麼都會【自動更改】我所設定的【讀寫權限】 ??? 😣
  • (2021-04-28) Alan DJIGSTAR: так то работает, шрифт подменяет, но в Chrome Vivaldi и прочем всё равно после Firefox все размазаннное, что глаза болят. Оценку снимаю за платность
  • (2021-02-24) Iñaki Jiménez Miranda: Ideal para personas que tiene resto de visión o para proyectar en la pared mediante el cañón proyector aumentando el tamaño de la letra.
  • (2021-02-06) Mia WallaceB52: Je viens juste de l'installer, principalement pour la taille de la police et c'est nickel, mieux que d'autres que j'ai testées par le passé. Je verrai à l'usage mais à priori je la conseille.
  • (2020-09-16) Bree Vwhyman: seems to work as it states.....thanks for the free EXTENSION. It is used here to increase the TEXT SIZE in the "messenger window" or the regular worldwide facebook web page page.
  • (2020-07-22) Andrey Kova: Работает как надо!
  • (2020-06-24) Alex S.: An extension that allows the user to increase and decrease the size of the ENTIRE web page. The key word ENTIRE is missing in the description!
  • (2020-03-07) Jing Li: it helped me a lot. Thanks author.
  • (2020-03-05) Brandon Lee: NExt refresh or open restore website default. (Mac latest, Chrome latest)
  • (2020-02-24) King Dedede: A bit confusing but it's still ok
  • (2020-02-02) Sheldon Buchler: I've tried most of the other extensions that claim they can change font size and this is the only one that does it in a reliable and consistent manner. It also has very easy to remember keyboard shortcuts. Highly recommend!
  • (2020-01-26) Ananstracated: Like people say, it is only a trial, because it won't save settings. That is why I use advance font settings and FC on my computer. The background changing with this extension makes it easy on the eyes. Google dropped external CSS support, but there is an extension that will use one, go to userstyles.org ..
  • (2020-01-05) Steve Z: I like the instant independent color changers for both font and background but Dark Mode extension by Grephy is faster and quicker that comes with a toggle switch for dark background that retains the setting for free even when you leave a page. The zoom-font function is also identical to (but slower than) Chrome's built-in zoom feature (accessible using Ctrl with + and - or Ctrl with the mouse scroll wheel) except that Chrome automatically remembers your setting without charging $4.99 for a Pro version... so you'd be paying that price just for the font and background COLOR settings to be retained. I'm keeping the Lite version extension for the color changers—it's nice to choose exactly what colors for long reading.
  • (2019-09-22) Andrew E: Great for small text websites like Wikipedia! Now I can do research without having to strain my eyes!
  • (2019-08-05) Matt Forrest: Working great so far. Many websites have white text on black background and it kills my eyes. I always set it to black text on a light coffee/cream background. Your eyes will thank you!
  • (2019-02-09) Randy Knowles: doesn't work
  • (2019-01-09) AloneEpic: Its Was Good Just That We Need To Pay For The App To Save The Font Color. And I Don't Want To Go Back And Forth To Change The Color
  • (2018-12-29) Come On Fhqwhgads: Nice. I was getting really tired of every website I look at on my huge desktop presenting itself like a blown up mobile version of the page.
  • (2018-11-25) 張廷光: 非常實用 讚
  • (2018-10-14) Monica Ornelas: I like this one, it was a good way to get my feet wet, in all honesty, I really like the the Pro better, just the fact that I own it along with other things lately that I have had to buy, it hit me, like a brick to the face.
  • (2018-08-29) Ting: 好用
  • (2018-07-05) Alеksandr Kovalenko: Отличное решение
  • (2018-07-04) mark klein: Works good just wish you could save changes.
  • (2018-06-01) Handsumguy Bo: I have used other extensions to change contrast or font etc in order to read text better and this works GREAT and hits the mark perfectly for me. It also improves the text on printed pages without causing any blurry action unlike other extensions I tried. I will take a look at the paid version.
  • (2018-05-06) vovx21: After 1.3.0 update, it started to messing up my new tab page. I use non-default page, which gets broken by your extension. __________ Now works well, however text color grid with bugs
  • (2018-03-22) restcure: Good at what it does, though it would be better described as a "demo", like other software that works the same as the paid version except that you can't save.
  • (2018-02-26) gg g: Does not work for all sites once changed. Will it work in Pro for all sites if once changed.
  • (2018-02-21) Somedumb Shmoke: Using the pro makes all the difference Love it.
  • (2018-02-10) Danny McCarthy: Useless product that tries to do too many things and fails miserably at all. [email protected]
  • (2018-01-24) Big Japko: Color change doesn't work (Chrome 63 Windows 7)
  • (2018-01-22) Deb Hickerson: Only changes background color, not font color.
  • (2018-01-12) Marx Santanna: Muito bom!!
  • (2017-11-10) Gersivan Oliveira: Útil para alguns casos.
  • (2017-10-29) Annie .B: Such a great extension! I wish I discovered it sooner. I would love to buy the pro version, but for some reason, I can't. A "price not available" message appears in front me instead.

    Hi! I’m a user who supports you to purchase copyright! I hope you can add an option to filter URLs! (Some websites don’t use this feature), because if you use this feature like 'Baidu Search', the screen will not be able to display part of it. The text is over! It becomes a black screen! In addition, some programs also have a [whitelist] option, so I hope you can add this option too! Thanks! Thank you!

    I loaded the lite version and it worked. I then paid for the pro version and deleted the lite version. Then the pro version wouldn't work at all so I reinstalled the lite version. Now when I press alt-+ pr alt uparrow the font size just goes large-amall-large-small over and over continuously. And apparently the pro version still doesn't work as the profiles don't work.
  • (2018-05-25, v:1.3.3) Robert Lindsay: Want to change font colors on all sites.
    I want to change the color in all webpages across the board. I do not want to have to go and change the font colors for each new page I go to. PITA. Also it never saves my colors. Say I have the fonts on a page set to grey, if I open the application, they are always switched back to the default. So the app does not remember the colors I specified for any given page.
  • (2018-03-31, v:1.3.1) Steve W.: New Tab Issue
    Thanks. I sure wish I knew that the Google search in new tabs was a known issue. I went to a lot off unnecessary and time consuming steps for nothing.
  • (2018-03-31, v:1.3.1) Steve W.: New Tab Issue
    Thanks. I just installed the latest update and so far it's working. Is there some way to have extensions update by themselves?
  • (2018-03-30, v:1.3.0) Steve W.: New Tab Issue
    Out of the blue, when I open a new tab, it goes to Google search! This only happens with your extension since the problem goes away if I turn it off.

  • (2017-06-28, v:1.2.4) Neil J: Bold
    Hi Mr. JB., For instance, on page https://www.civilized.life/articles/car-accidents-legal-marijuana/ , the font "size" is OK. But I'd like to change the spindly font to "Bold." That would be sufficient. ------ Also, I'd go Pro for remembering the font size for each website, but I'm reluctant to give Google my credit card info. I don't remember them offering Paypal (as if Paypal is better). I'm up to about two dozen extensions, and A+ FontSize Changer Pro is the only one that I'd feel enthusiastic about paying for.
