Fonts on the tab you already have open
DevTools works. It is also four panels deep when you only wanted a family name.
The FontScanner Chrome extension lists the fonts on the active tab in one click. Open the toolbar popup, or right-click the page and choose Identify fonts with FontScanner. An overlay can highlight type on the page itself.
Detection is local: computed styles and @font-face already loaded in the tab. Nothing is sent to FontScanner unless you click through for a license check, a full-site scan, an image match, or the API.
What the popup is for
- See family names on the current page without opening DevTools
- Jump to a quick homepage license check for that host
- Start a full website or PDF scan when the page is only the tip
- Open image scan when the type you care about is in a screenshot, not in CSS
- Reach the developer docs when you want the same check in CI
The extension is a lens. FontScanner.app is the audit.
Privacy, on purpose
- No background crawl
- No remote code
- No upload of page HTML unless you continue on the site
activeTab+scriptingonly when you click the icon or the context-menu item
That is the same contract as the store listing: identify fonts on the page you asked about, then get out of the way.
Local list vs a FontScanner report
The popup shows what the browser computed on this document. A quick website scan re-fetches the homepage and flags commercial families. A credited full audit walks inner pages, linked PDFs, and can match your license inventory.
Use the extension to notice. Use a scan to document.
Install
Load it unpacked while the Chrome Web Store listing is in review:
- Open
chrome://extensions - Enable Developer mode
- Load unpacked and select the
extensionfolder from the FontScanner repo (the one that containsmanifest.json) - Pin the icon
Do not load a .pem or .crx. Google signs the store package.
When the listing is live, install from the Chrome Web Store the usual way — one click, same local detector.
Conclusion
If you already have the page open, you should not have to paste the URL to learn the typeface. The extension reads the tab. FontScanner still does the license work when you ask.
