Wolfie Font Swapper

About

See any website in a different font — instantly.

Wolfie Font Swapper lets you preview and swap fonts live on any page, so you can find the perfect typeface before you ever touch your code. Pick a font, watch the page change in real time, fine-tune it, then copy production-ready CSS in one click. Built as a fast, no-friction tool for designers and developers. Perfect to COPY/PASTE to the AI prompt as well.

WHAT IT DOES
• Live preview on the real page — hover a font to see it applied instantly; click to commit. No reload, no guessing.
• Swap whole-page or target areas separately — set different fonts for the whole page, headings (h1–h6), paragraphs, navigation and buttons.
• Google Fonts + your system fonts — 300+ Google families loaded on demand, plus the fonts actually installed on your machine.
• Fine control — weight, size, line-height, letter-spacing, letter case and color, per area.
• Presets — save your favorite font setups and switch between them in one click (e.g. Editorial, Mono, Brand).
• Per-domain rules — save a font setup for a site and it auto-applies every time you come back.
• Font picker (inspector) — point at any element on a page to see its font and license, copy its CSS style, add it to your library, or apply it to the whole page in one click.
• Copy ready-to-use code — export your choices as CSS, SCSS or JS instantly.
• License tags — every font is labeled Web-safe / Free / Premium / System, so you always know what you can use.
• 9 languages — English, Polski, Français, Deutsch, Español, Українська, Русский, Română, Italiano.

PERFECT FOR
• Designers comparing typefaces on real content before committing.
• Developers grabbing exact font CSS without DevTools digging.
• Anyone who wants a more readable, better-looking web.

PRIVACY FIRST
No tracking. No analytics. No data collection. Everything you configure stays in your browser. The extension reads only a page's hostname to apply your saved rules — never your content or anything you type

PRO (optional)
A Pro subscription unlocks unlimited presets. The free version is fully functional.

Stop imagining how a font would look — see it, on the page, right now.
