The easiest way to identify fonts on web pages.

Image from store WhatFont
Description from store What is the easiest way to find out the fonts used in a webpage? Firebug and Webkit Inspector are easy enough to use for developers. However, for others, this should not be necessary. With this extension, you could inspect web fonts by just hovering on them. It is that simple and elegant. It also detects the services used for serving the web fonts. Supports Typekit and Google Font API. Recommended by Wired WebMonkey, Lifehacker, and SwissMiss.

  • (2022-08-01) Darryl Edwards: App is OK but find it unusual that I can't examine font via the right click menu on the page. It's not good UX to access from a menu within a menu. Even if I pin to taskbar, it's not as accessible as it would be via right click on the page. Uninstalled and installed "Find Font" instead
  • (2022-07-31) Jennifer Reed: I design Word documents and often visit my clients' websites to get a feel for their design preferences. Previously, I had to go through rigamarole: clicking F12 and digging through the source code. It was difficult because I had no idea what I was doing. Using the WhatFont extension is so easy! Click it and hover over the text on the page. That's it. It also displays the font weight, size, and even the color (so helpful). I highly recommend this extension to anyone wanting to know what fonts are used on websites.
  • (2022-07-28) prinny cupcakes: hmm extension seems to be good & working.. not too sure about all the virus problems.. anyone can confirm again? i've had the app for many years
  • (2022-07-07) Mounir El-Abbas: Comes freshly packed with a virus Do not download. It comes with a browser-redirect feature that is not welcome.
  • (2022-06-25) Jules the Boombox Zombie: It helps me locate where my favorite fonts are and the ones exclusively used in the Starfall.com website (e.g. Starfall Block).
  • (2022-06-15) Matthew Cirola: Works great
  • (2022-05-19) UPAN Fry Pan: This works well I have been using it for a few years and has proven a excellent tool in getting the font and text spacing right
  • (2022-05-12) Krystal Hudson: Doesn't work. I have tried to use it 101 times and not once has it worked.
  • (2022-04-26) On Game: Nice, thank you!
  • (2022-04-21) Boogiepop: Amazing, this one is a must for every web developer! 🔥❤️🙏
  • (2022-04-16) Freedom Wings: I badly want this font ID extension, but it doesn't work for me in Chrome, except ONLY on the dev's test page :P. On all other webpages, when I click on the extension, all that happens is the menu drops down. If there is a known issue that stops it from working, this should be listed on the dev's website. If someone can please respond to tell me how to get this to work, I'll change my rating. I want to love it. Thanks! :) Update: Rating upgraded from 1 to 3 stars -- Had to uninstall and reinstall. Only then did refreshing the page work for 2 out of 5 webpages, but not on the 3 others. Is this extension restricted on certain types of webpages? Helpful Input would be appreciated. Thanks! :) (Also, on some webpages, the font ID bubble is so far below the font pointer, that if the font is near the bottom of the page, then you can't see the ID bubble because it drops out of site.)
  • (2022-04-14) 1118_Hafiz Sakib: How to use it? It didn't hovered anything on mouse pointer
  • (2022-04-06) Abdul Mubeen: Amazing tool. Works perfectly
  • (2022-04-05) Ahmad ALi: Its Good but did not tell the Letter Spacing . Please add this feature as well. Thanks
  • (2022-04-04) Janis Peipins: very good
  • (2022-03-18) Michele Rumi: Amazing, especially love that it also gives the color and so much other info
  • (2022-03-06) Máté Kuna: Wasnt disappointed there is an addon even like this for chrome! After clicking the addon icon it instantly shows font name, and more details as well!
  • (2022-03-01) Rahul Hasan: i think its a great and lightweight plugin...
  • (2022-02-23) Fynn: Doesn't seem to do anything . . . except read my information on all websites.
  • (2022-02-23) Samuli Asmala: BEWARE OF MALWARE! When I modified my Google search results this extension always forwarded me to searchwithpure.com. After removing this extension the problem disappeared.
  • (2022-02-13) SoloSlater: Works very good. Fonts are cool
  • (2022-02-09) Anthony Tumiwa: it's not really accurate, i got some wrong identification
  • (2022-02-03) Marta Rabadan: A aquellos que no os funciona, seguramente tenéis que reiniciar el navegador. Una vez reiniciado clickais en el botón de la extensión y funciona guay.
  • (2022-02-02) Dinesh Gupta: What if the developer has changed the font-family name in the css?
  • (2022-01-30) Jinka Rakesh: If anyone feels like it's not working , just click extension icon once and click on text you want to recognize, if it doesn't work yet. Just refresh the page. Click on extension icon again to exit whatFont. Now, the extension stops working in background reading website data.(Last sentence for people with privacy issues.)
  • (2022-01-22) Hiệp Nguyên: Hay lỗi
  • (2022-01-18) Eric Liphardt: Installed Malware on my Mac - beware! When turned on this extension tried to download .js files from a site called funsource.net every time I did a Google search. Caught by my antivirus. Uninstall!
  • (2022-01-16) Arty: No sirve!
  • (2022-01-13) Danielle Miller: it doesn't work. Some spammer is going to call me a liar misspelled, but it just doesn't work, regardless of refreshing, clicking the extension, hovering, trying to see if there's a setting off, or what. It just doesn't work.
  • (2022-01-11) Ntsoalalaina Ralijohn: Worked perfectly! This will save a lot of time and hassle. Thanks
  • (2021-12-27) Lee Moreau: Doesn't work at all. It only works on their test page, any other page clicking the icon just opens a dropdown and does nothing. Uninstalling since it's GARBAGE.
  • (2021-12-14) Alireza Rostaminia: Amazing but the logo doesn't be synced with Auto Dark/Light mode on MacOS. Would you please fix this?

  • (2021-10-29) Shayan Babar: Time Waste
  • (2021-10-27) Chandima Karunaratne: Love the extension but the logo becomes invisible if you're in dark mode (for chrome). Idk if its possible to have a dynamic logo that changes color, but its pretty much invisible when in dark mode :/

  • (2021-10-21) Edvin Åberg: doesn't work
  • (2021-10-15) Antluh Wood: As a web developer it would be good to use it without reloading as many programs can't load exactly as when reloaded. Thanks!
  • (2021-10-03) Mahfoudh Bouboutt: I love it. It does one thing and it does it well.
  • (2021-09-21) Faruk Mia: It doesn't work.
  • (2021-09-11) Міла Галько ІП-01: НЕ РАБОТАЕТ
  • (2021-09-09) Kamrul Hasan Raza: Great app. I use it often to learn about fonts
  • (2021-09-03) David Camp: It works as expected
  • (2021-09-03) Najla N. A: It's great, now i don't need to use developer tool (press f12/Cntrl+Shift+I), and just need to use it with simple click. For some people that don't understand; You need to click the extension icon and hover it to the text to make it show the font, and you can exit using the font by click the extension icon again or the button on the upper left written "Exit WhatFont". And If the extension doesn't work; Try to REFRESH THE TAB/PAGE (all extension, anytime after you adding/enable any extension to your browser you need to refresh the page, or restart the browser, it's both the same.) If it's still not working, try to reinstall. If all that still not working, then maybe it's just broken. Btw I like how you can change the extension icon appearance, It's cool so when I switch my browser theme, the extension will still look nice:)

  • (2021-07-07, v:2.1.0) Karen Yin: Bug
    I have been using WhatFont for years and it's not working the past few weeks, hence I uninstalled it. It stopped working like it used to be. If I click at the icon on the top, it will only show the dropdown to go to a webpage/Options/Remove. The behavior changed completely and I couldn't "turn on". On top of that, my default search bar all of a sudden changed from google to yahoo and other malware search site. This behavior stopped once I uninstalled this plugin. Took me awhile to figure out because I have been using it the longest time and it's the last plugin I disabled. Your code may have security issue.
  • (2021-05-23, v:2.1.0) Brandon Gosnell: hijacking my searches

  • (2019-09-24, v:2.1.0) Frank Dana: "Exit" button is hidden behind menu, when open
    Because the "Exit WhatFont" button appears in the upper right corner of the page when the extension is activated, if the extension has been moved to the Chrome menu (instead of the toolbar) then the button will be invisible because it's completely covered by the menu. This makes it very difficult to determine whether the extension is activated or not — you have to open the menu, click the icon, click outside the menu to close it, and then look for the "Exit WhatFont" button. Perhaps the button could appear in the lower right (or even lower left) corner, instead of the upper right?
