What WhatFont is

After activating it from the toolbar, hovering over text shows the font family, and clicking an element opens a details panel. The developer says version 3.3.0 added real font names, where the font comes from, letter spacing, line height, and one-click copying of individual values or all the CSS.

Tradeoffs to know

  • Middling store rating for its scale
  • Some pages prevent it from running
  • Does not tell you a font's license terms

Permissions and privacy

Page access

WhatFont runs when you activate it from the toolbar on the page you want to inspect, then reads computed styles for the text you hover. The developer says version 3.0 revised its permission model to better respect privacy. Inspecting local files needs Chrome's Allow access to file URLs setting turned on for the extension.

Data notes

The listing declares that the developer does not collect or use your data. Font detection works from the computed styles of the page in front of you, and the listing describes no account, sync, or cloud component, which makes it a low-exposure tool to keep installed.

Pricing

Free, with no paid tier. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
