Font Checker Support
Font Checker is an iPhone Safari extension for inspecting fonts and typography by tapping text on a webpage.
Initial Setup
- On iPhone, open Settings > Apps > Safari > Extensions. On earlier iOS versions, open Settings > Safari > Extensions.
- Select Font Checker and turn on the extension.
- Open a regular HTTP or HTTPS webpage in Safari.
Inspect a Font
- Open Safari's extensions menu from the toolbar and choose Font Checker.
- Tap the text you want to inspect. A panel shows the likely rendered font, CSS font-family, size, weight, line height, spacing, colors, and related details.
- Copy the font name or details as needed, and revisit saved results in History.
History and Data Deletion
When enabled, history is stored only on device and retains up to 100 entries. In the app's Settings, you can turn off history or use Clear All History to delete saved entries.
Unsupported Content
Safari's start page, settings pages, some PDFs, and frames embedded from another website may not allow the extension to run. Text drawn inside images, video, or canvas is not supported.
Browsers may use different fallback fonts for different characters, so Font Checker presents the rendered font as an estimate alongside the CSS declaration.
What to Include When Contacting Support
- Your iPhone model and iOS version

- The type of page and steps that produced the issue
- Any error message shown
FAQ
The extension does not appear
Open Safari's Extensions list in Settings and confirm that Font Checker is turned on. If it is still missing, restart your iPhone and check again.
Nothing happens after I choose Font Checker
Reload the webpage and choose Font Checker again. Try a regular HTTP or HTTPS webpage rather than an internal Safari page.
Are browsing content or inspection results uploaded?
No. Font Checker does not send browsing content or inspection results to CAEN or third-party servers. If you enable history, the data remains on your device.
Is this a subscription?
No. Font Checker is a paid-up-front app with no in-app purchases or subscriptions. Check the App Store for the price in your region.
