WOFF2 to WOFF Converter

Converting WOFF2 to WOFF re-compresses the font with zlib instead of Brotli. The result is larger but supported on older browsers that don't handle WOFF2, mainly IE9–11 and Safari before version 10. Useful for multi-format @font-face declarations.

What changes when you convert WOFF2 to WOFF

Lossless conversion. The font data is identical; only the compression algorithm changes. WOFF files are typically 30% larger than WOFF2. The tradeoff is broader browser support.

When to use this conversion

  • Adding a WOFF fallback to an existing WOFF2-only font delivery setup
  • Supporting legacy browsers (IE9–11) without giving up on modern font delivery
  • Matching a site's browser-support matrix that includes pre-2017 browsers
  • Preparing multiple format tiers for a progressive @font-face declaration

Where the output works

WOFF works in every browser since IE9 (2011). It's the broadest web-font compatibility format short of raw TTF/OTF.

About these formats

WOFF2 (Web Open Font Format 2)

WOFF2 uses Google's Brotli compression instead of zlib, cutting file size another 30% versus WOFF. It's the current standard for web font delivery, supported in every modern browser since 2017. A typical Latin-only WOFF2 is 20–40% the size of the source TTF.

WOFF (Web Open Font Format)

WOFF (Web Open Font Format) is a 2010 wrapper that zlib-compresses a TTF or OTF for web delivery. Files are roughly 40% smaller than raw TTF/OTF, with the same glyph data preserved exactly. WOFF works in every browser back to IE9 and exists primarily for the web.

How It Works

  1. Add your WOFF2 files Drag WOFF2 fonts onto the page, or click to pick them from your file browser. Batch uploads are fine.
  2. Convert to WOFF The converter reads the WOFF2 tables and rewraps them in WOFF form with appropriate compression.
  3. Runs in your browser Everything happens locally via WebAssembly. Nothing uploads. Font files stay on your device.
  4. Download WOFF files Grab each converted file individually, or download the whole batch as a single ZIP.

FAQ

Why convert WOFF2 to WOFF?

Only for legacy browser support. Modern browsers all handle WOFF2 directly. Adding a WOFF fallback is worth it when your audience includes IE9–11 users or very old Safari versions.

Will anything be lost?

Nothing. Both formats are lossless wrappers. The font data is identical; only the compression changes.

Are my files private?

Yes. The converter runs entirely in your browser using WebAssembly. Your font files are never uploaded, never sent to a server, and never leave your device.

Is there a file size limit?

There's no hard limit. Font files are usually small (under a few MB), so even very large fonts process without issue. Variable fonts with many axes are handled cleanly.
