How to use

1

Upload your font

Drag and drop a TTF or OTF file onto the upload zone, or click to browse. The font loads instantly in your browser — no server upload needed.

2

Configure @font-face

Set the font-family name (defaults to the filename), font weight, style, and font-display. Choose 'swap' for the best performance in almost all cases.

3

Choose a fallback stack

Select a fallback font stack (Sans-serif, Serif, Monospace, or System UI). This ensures readable text even if the custom font fails to load.

4

Copy & deploy

Copy the @font-face CSS, usage snippet, and Tailwind config. Download the full CSS file. Upload your font to your server's /fonts/ directory and add the CSS.

When to use custom web fonts

Brand identity

Custom fonts are a core brand asset. A unique typeface makes your website instantly recognizable and differentiates you from competitors using generic system fonts.

Publishing platforms

Blogs, news sites, and documentation platforms use custom fonts to maximize readability for long-form content. Serif fonts can increase reading comfort for dense text.

SaaS products

Modern SaaS products use carefully chosen sans-serif fonts to convey professionalism, clarity, and technical credibility in dashboards and UI components.

Creative portfolios

Designers and agencies use expressive display fonts for portfolio headlines and project titles — impossible to achieve without custom @font-face implementation.

eCommerce stores

Product typography directly affects conversion. Premium-feeling fonts make products feel more desirable. Consistent typefaces build customer trust across product pages.

Mobile apps (PWA)

Progressive Web Apps use @font-face to match their native app counterparts. Consistent typography between web and native experiences reinforces product quality.

How it works

FontFace API

The browser's FontFace constructor loads the TTF or OTF from an ArrayBuffer (read by FileReader) directly into the browser's font engine without any server upload. A unique name prevents conflicts with system fonts.

Live preview

The preview applies the loaded font via fontFamily CSS on the preview container. Switching modes renders different HTML structures — headings, paragraph, specimen, hero, and UI — all using the same loaded font.

@font-face generator

The CSS generator assembles the @font-face block from your settings: the public filename (for your server), format string (truetype or opentype), weight, style, and display property. The usage snippet shows the complete font-family stack.

100% browser-side

All processing — file reading, font loading, preview rendering, CSS generation — happens in JavaScript in your browser tab. No files are transmitted to any server. Your font assets remain private.

Frequently asked questions

Quick answers about this free online tool.

@font-face is a CSS rule that lets you embed custom fonts directly in a webpage. Instead of relying on fonts installed on the user's device, you host the font file on your server and reference it with @font-face. The browser downloads the font and applies it. The key properties are font-family (the name you'll use in CSS), src (the file URL and format), font-weight, font-style, and font-display (controls loading behavior).

WOFF2 (Web Open Font Format 2) is the recommended format for modern web use — it compresses 30–40% better than TTF or OTF and is supported by all browsers released after 2015. For maximum compatibility including older browsers, you can include both WOFF2 and WOFF in the src list. TTF and OTF work in all modern browsers too, but their larger file sizes make WOFF2 the clear winner for performance.

WOFF2 is a compressed web font container format designed specifically for the browser. It wraps a font (which may originally be a TrueType or OpenType font) in a compressed package using the Brotli algorithm, resulting in significantly smaller file sizes than the raw TTF or OTF. A 400 KB TTF file typically becomes ~150 KB as WOFF2. Smaller files mean faster page loads and better Core Web Vitals scores.

Three steps: (1) Upload your font file (TTF, OTF, or WOFF2) to your web server — typically in a /fonts/ directory. (2) Add a @font-face rule in your CSS pointing to the file: @font-face { font-family: 'MyFont'; src: url('/fonts/myfont.woff2') format('woff2'); font-display: swap; }. (3) Use the font in your CSS: body { font-family: 'MyFont', sans-serif; }. This tool generates steps 2 and 3 automatically based on your uploaded font.

Yes — extend the fontFamily key in your tailwind.config.js. For example: theme: { extend: { fontFamily: { custom: ['MyFont', 'sans-serif'] } } }. Then use it with the class font-custom. You still need to add the @font-face rule in your global CSS (or import the font from Google Fonts). This tool generates both the @font-face CSS and the Tailwind config snippet.

font-display: swap tells the browser to show the fallback font immediately while the custom font loads, then swap to the custom font once it's ready. This prevents invisible text (FOIT — Flash of Invisible Text) during loading. The alternatives are: block (brief invisible period), fallback (short invisible period then permanent fallback if slow), and optional (use fallback if font isn't cached). For most text, swap is the recommended choice for the best balance of performance and user experience.

Typography is one of the most powerful design tools — it establishes brand identity, improves readability, creates visual hierarchy, and communicates tone. Web fonts let designers move beyond the small set of fonts installed on users' devices (Arial, Times New Roman, Georgia) to any typeface that suits the brand. Well-chosen custom fonts can increase time-on-page, reinforce brand recognition, and significantly elevate the perceived quality of a website.

A font fallback stack is a comma-separated list of font families in the font-family declaration. If the first font fails to load, the browser tries the next one. For example: font-family: 'MyFont', Arial, sans-serif. The browser uses MyFont if available, falls back to Arial if not, and finally uses any available sans-serif font. This ensures your text is always readable — even if the font file fails to download due to a network error or slow connection.
