Font Previewer

See how different fonts look on any website, before you decide.

↑ Drag this button up to your bookmarks bar

Or just click it to try it on this page first.

Heads up: this is a bookmarklet for desktop browsers (Chrome, Edge, Firefox, Safari). Open this page on a computer to add it.

1. Drag the button up onto your bookmarks bar - the strip of saved links near the top of your browser.
2. Go to any website you want to change.
3. Click the button you just saved. A small panel opens in the corner - pick a font from it and the website updates instantly.

No bookmarks bar? Most browsers can switch one on (try Ctrl+Shift+B, or ⌘+Shift+B on a Mac). If yours can't, copy the button and paste it in as the web address of a new bookmark.

Works on most websites. A few (like GitHub, X, or online banking) block bookmarklets for security — if nothing happens, just try it on another site.

Try as many fonts as you like, use different fonts for headings, body and buttons, tweak size and weight, or upload your own — then copy the CSS for your site. Nothing is installed.

Your privacy

No accounts and no tracking of the pages you visit. The tool reads a page only in your browser (to detect or restyle its text) and never sends that anywhere. Fonts you upload stay in your browser — they're never uploaded.

Two things do reach the internet, like on any normal website: it counts anonymous, aggregate usage (how often it's opened — no personal data), and to preview a font it loads that font from Google Fonts or Fontshare, so those services see your device's IP address, exactly as they would on any site that uses their fonts.
