About FontScanner
FontScanner finds the fonts on a website, inside a PDF, or in a screenshot — and puts them in a clear report, including commercial typefaces that may need a review. You can also schedule recurring website scans, run a free homepage check, use the Chrome extension, call the developer API, or deploy the whole product on-prem.
Why FontScanner exists
Most teams cannot name the fonts a live site actually loads. Themes, CDNs, screenshots, and linked PDFs add typefaces that never made it into the brand guide.
We crawl a site the way a browser does, read a PDF you upload, or match visible type in an image. Recurring website scans can run on a daily, weekly, or monthly schedule — in our cloud or on-prem. The same engine powers a free homepage checker, a Chrome extension, a CI API, and an on-prem install for teams that need scans to stay inside their network. The report lists every font we found and flags known commercial families so you can decide what to do next.

See how an on-prem install works →Ways to use FontScanner
Scheduled crawls, a free homepage check, the Chrome extension, a CI API, image scans — plus on-prem for teams that keep everything inside their network.
On-premises
We can install FontScanner on your infrastructure. Talk to us.
See on-prem →Scheduled scans
Daily, weekly, or monthly website crawls from the dashboard. Same report, without starting it by hand. Cloud and on-prem.
Open scheduled scans →Image scan
A screenshot, logo, or mockup is enough when you do not have a URL. We match visible text and flag commercial licensing risk.
Identify fonts from an image →Quick website scan
No account. We check the homepage only — two free checks per day per IP — so you can see if a full crawl is worth a credit.
Try the homepage checker →Chrome extension
Fonts on the tab you have open, in one click. Detection stays on your device until you choose a license check or a deeper scan.
Add to Chrome →Developers
Enterprise CI/CD: website, PDF, and image jobs from your pipeline. Contact sales for an API key — keys are not created in your profile.
Open the developer docs →How it works
From a URL, a file, a screenshot, or the tab you have open — to a report or JSON.

We find the fonts
Pages, CSS, JavaScript, CDN links, linked PDFs, embedded PDF fonts, or visible type in a photo.
You get a report — or JSON
A list of fonts, commercial flags, and where they appeared. Export as PDF or receive a webhook.
What we detect
FontScanner finds fonts on live sites, inside documents, and in images.
Google Fonts & Bunny Fonts
Fonts loaded via CDN links, link tags, and @import rules.
Adobe Fonts / Typekit
Commercial fonts loaded through Adobe's Typekit JavaScript and CSS endpoints.
Self-hosted fonts
WOFF, WOFF2, TTF, and OTF files served from your domain via @font-face rules.
CSS stacks & system fonts
font-family declarations in stylesheets, inline HTML, and computed page styles.
Uploaded & linked PDFs
Embedded fonts in PDFs you upload, plus PDFs linked from pages during a site crawl.
Screenshots & images
Visible type in a photo, logo, or mockup — matched against the catalog and flagged when a commercial license is likely.
What the report covers
The same sections you see on a completed scan.
Commercial fonts
Paid typefaces loaded or distributed from the site, with vendor and pages.
PDFs
Embedded fonts in a file you uploaded, or in PDFs linked from the site.
Page by page
Which page loaded which font, and from which CSS or JS file.
License management
You can also keep an inventory of licenses you own. When you scan, those records are matched to the commercial fonts in the report.
Your license list
Store font name, vendor, type, covered domains, seats, dates, and a proof-of-purchase file.
Matched to scan results
Commercial fonts found on a site or in a PDF are checked against your inventory on the same report.
Who it is for
Anyone who needs a straight answer: which fonts are on this site, in this file, or in this screenshot?
Agencies & studios
Check a client site, a deliverable PDF, or a mockup screenshot before launch.
Brands & stores
See what actually loads on marketing pages and in sales PDFs — or run a 10-second homepage check.
Developers
Catch fonts added by a theme, a widget, or a CDN change — locally in Chrome, automatically from CI on the Enterprise plan, or from an on-prem API inside your network.
IT & security
Keep crawl data on your PostgreSQL or SQL Server. On-prem is for teams that cannot send site content to a SaaS crawler.
