Font Finder Extension Guide: Detect Fonts Without Screenshots

Install a browser extension to hover any text and see its font instantly.

Extension vs detector vs DevTools — when to use each for speed and privacy.

Extensions read the live DOM, so they work on authenticated pages where a URL fetcher can't.

Setup

Pin the extension, allow on file URLs if you inspect local HTML.

Hover text → see family, size, weight, color. Click to copy CSS.

We never store pages; everything stays local.

This guide pairs with our detectors — no signup, runs locally where possible.

Inspect any URL or pasted HTML/CSS to list all web fonts, sizes, weights and where they're used on the page.

Step-by-step for Chrome DevTools, our Website Font Detector and what to do on private sites.

From PSD/XD to web equivalents — handling Adobe Fonts activation and fallbacks.
