When to Convert

Common scenarios where this conversion is useful

Creating fallback fonts for Internet Explorer

IE9-11 support WOFF but not WOFF2. If your site must support these browsers, convert WOFF2 to WOFF to provide a fallback in your @font-face stack.

Supporting older Android browsers

Some Android 4.x browsers and older WebView implementations support WOFF but not WOFF2. Generate WOFF versions for these legacy mobile environments.

Email client font embedding

Some email clients support web fonts via @font-face but only recognize WOFF. Convert WOFF2 to WOFF for email templates that use custom fonts.

Building a complete @font-face stack

Best practice is to provide both WOFF2 (primary) and WOFF (fallback). If you only have WOFF2 files, generate the WOFF fallbacks from them.

Frequently Asked Questions

Why would I convert WOFF2 back to WOFF?

The main reason is legacy browser support. IE9-11 and some older mobile browsers support WOFF but not WOFF2. Converting creates a fallback for these environments.

How much larger is WOFF compared to WOFF2?

WOFF files are typically 20-30% larger than WOFF2 for the same font. The difference comes from zlib being a less efficient compressor than Brotli for font data.

Is any quality lost in the conversion?

No. Both WOFF and WOFF2 are lossless container formats. The font data — glyphs, kerning, features, metrics — is identical in both formats.

Do I still need WOFF fallback in 2024+?

For most websites, WOFF2-only is sufficient as it covers 95%+ of global browsers. WOFF fallback is only necessary if you must support IE or very old mobile browsers.

How do I use both WOFF2 and WOFF in CSS?

List WOFF2 first in @font-face src: src: url('font.woff2') format('woff2'), url('font.woff') format('woff'). Browsers use the first supported format.

Is my font data private?

Yes. The conversion runs entirely in your browser using JavaScript. No font data is sent to any server. This is safe for all licensed and proprietary fonts.

Are variable fonts supported?

Yes. Variable font data is preserved during conversion. However, note that IE and older browsers that need WOFF may not support variable fonts anyway.

Can I convert color fonts from WOFF2 to WOFF?

Color font tables (COLR, CPAL, sbix) are preserved in the output. Browser support for color fonts in WOFF depends on the specific color table format.

Will the font render the same in WOFF?

Yes. WOFF and WOFF2 contain the same font data, just with different compression. The rendering is pixel-identical across both formats in any browser.

Can this tool also do WOFF to WOFF2?

Yes. ChangeThisFile offers both directions. Use the WOFF to WOFF2 converter to upgrade fonts to the smaller Brotli-compressed format.
