# WOFF vs. WOFF2: The Only Font Format You Need in 2026

For years, developers included a "bulletproof" stack of font formats (`.eot`, `.ttf`, `.svg`, `.woff`, `.woff2`) to ensure compatibility with Internet Explorer and older mobile browsers.

In 2026, this is no longer necessary. You only need **WOFF2**.

## 1. What is WOFF?
**WOFF (Web Open Font Format)** was standardized in 2010. It is essentially a wrapper around a standard TrueType (.ttf) or OpenType (.otf) font file.
*   **Compression:** It uses **zlib** compression (same as Gzip) to reduce file size.
*   **Metadata:** It allows foundry metadata to be attached to the file without affecting rendering.

## 2. What is WOFF2?
**WOFF2** was standardized in 2015. It is the successor to WOFF.
*   **Compression:** It uses the **Brotli** compression algorithm.
*   **Performance:** WOFF2 files are typically **30% to 50% smaller** than WOFF files.
*   **Parsing:** It is designed to be decompressed faster by the browser, speeding up the rendering pipeline.

## 3. Why Drop Legacy Formats?

### The "Bulletproof" Syntax (Obsolete)
You might see old tutorials suggesting this massive block of CSS:

```css
/* DO NOT USE THIS IN 2026 */
@font-face {
  font-family: 'MyFont';
  src: url('myfont.eot'); /* IE9 Compat Modes */
  src: url('myfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('myfont.woff2') format('woff2'), /* Super Modern Browsers */
       url('myfont.woff') format('woff'), /* Pretty Modern Browsers */
       url('myfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('myfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}
```

### The Modern Syntax (2026 Standard)
Since Internet Explorer is officially dead and all modern browsers (Chrome, Firefox, Safari, Edge) support WOFF2, you can simplify your CSS to just this:

```css
/* THE 2026 STANDARD */
@font-face {
  font-family: 'MyFont';
  src: url('myfont.woff2') format('woff2');
  font-display: swap;
}
```

### Browser Support
*   **WOFF2:** Supported by 98%+ of global users.
*   **The Remaining 2%:** Mostly Opera Mini or extremely old Android browsers that likely struggle to render modern JS anyway. For 99.9% of WordPress sites, serving a fallback is wasted bandwidth for the majority.
