Website Font Detector
Detect all fonts used on any website — families, weights, and sizes. No sign-up required. 3 free scans per day.
How it works
Enter a URL
Paste any website URL. We load the page in a real Chromium browser.
We scan computed styles
Our engine reads every element's computed font-family, font-weight, and font-size from the live DOM.
Get the font list
All unique font families, their weights, usage context (heading, body, UI), and occurrence counts.
Who it's for
FAQ
What fonts does the detector find?
It finds all font families actually rendered on the page — including web fonts loaded via @font-face, Google Fonts, Adobe Fonts, and system fonts. It reads computed styles from the live DOM, so it captures fonts applied by CSS frameworks like Tailwind or Bootstrap.
Does it detect font weights and sizes?
Yes. For each font family, we report all font-weight values used (e.g. 400, 500, 700), the body font size, body line height, and the heading size scale (h1 through h6).
How is this different from the Site Audit tool?
The Font Detector focuses only on typography. The Site Audit tool extracts fonts plus colors, headings, tech stack, accessibility contrast ratios, and metadata — a complete design token extraction.
