What is @font-face CSS?

The @font-face CSS at-rule allows web developers to specify custom fonts to display text on their websites. Instead of being limited to web-safe fonts installed on users' computers, you can use any font by providing the font files and telling the browser how to use them.

A properly configured @font-face rule includes the font family name, source files with format hints, and optional properties like font-weight, font-style, and font-display for optimal loading behavior.

fallback	Short block (~100ms), swaps within ~3s or uses fallback	Balance between speed and consistency
optional	Very short block, only swaps if immediately available	Performance-critical pages
auto	Browser default (usually similar to block)	Legacy behavior

Frequently Asked Questions

What is @font-face?

@font-face is a CSS at-rule that allows you to define custom fonts for use on your website. It specifies the font file location, format, and properties like font-weight and font-style.

How do I use the generated CSS?

Copy the generated CSS code and paste it into your stylesheet, or download the CSS file and link it in your HTML. Make sure your font files are accessible at the paths specified in the CSS.

What font formats are supported?

This tool supports WOFF2, WOFF, TTF, OTF, EOT, and SVG font formats. WOFF2 is recommended for modern browsers due to its superior compression.

Is my font file uploaded to a server?

No. This tool processes everything in your browser using JavaScript. Your font files never leave your device, ensuring complete privacy and security.

What is font-display and which should I use?

font-display controls how fonts are displayed while loading. 'swap' (recommended) shows fallback text immediately then swaps when loaded. 'block' hides text briefly. 'fallback' and 'optional' offer progressive enhancement.

Can I generate CSS for multiple fonts at once?

Yes! You can upload multiple font files at once. Each font gets its own @font-face rule with customizable settings for family name, weight, style, and display.

What's the difference between font-weight values?

Font-weight ranges from 100 (thin) to 900 (black). Common values: 400 is normal/regular, 700 is bold. Use the weight that matches your font file (e.g., a Bold variant should use 700).
