❓ Frequently Asked Questions

What font formats are supported? ▼

TTF, OTF, WOFF, and WOFF2. Most modern browsers support these formats. WOFF2 is recommended for best compression.

Is my font uploaded to a server? ▼

No! Everything happens in your browser. Your font file never leaves your device. The tool uses the FileReader API and FontFace to load the font locally.

What does the base64 @font-face code do? ▼

The CSS includes the entire font file as a base64 string inside the src property. This is a self‑contained way to embed the font directly in your CSS – useful for demos or small projects, but not recommended for production due to size.

Can I use the generated CSS on my website? ▼

Yes! Copy the CSS and paste it into your stylesheet. The font will be embedded as a data URI, so no separate font file is needed. However, be mindful of file size – large fonts can bloat your CSS.

🧠 Why Use Custom Fonts?

Custom fonts give your website a unique identity. They allow you to match your brand typography exactly, create a consistent user experience, and stand out from the crowd. With the @font-face rule, you can embed any font and use it just like a system font.

🎯 Brand consistency

Use your own fonts to reinforce your brand image.

⚡ Performance

WOFF2 offers excellent compression; use data URIs only for small fonts.
