WOFF2 → WOFF

Need the other direction? WOFF → WOFF2 →

Easily convert your WOFF2 font files to the WOFF format for improved compatibility with older web browsers. This tool is essential for developers maintaining legacy web projects.

WOFF2 uses the Brotli compression algorithm, which offers superior compression ratios compared to the original WOFF format. When you convert from WOFF2 to WOFF, the file is decompressed and re-encoded using the zlib compression standard. This process essentially bridges the gap between modern font performance and the specific technical requirements of legacy browser environments that do not support the Brotli-based WOFF2 standard.

The conversion is lossless, meaning the glyph outlines, kerning data, and font metrics remain identical to the original file.

Tips

Check your analytics to ensure the WOFF format is strictly necessary for your user base.
Keep the original WOFF2 file as a backup for modern browsers.
Verify that your CSS @font-face rules are updated to point to the new WOFF file path.

Common use cases

Supporting legacy browsers like Internet Explorer 11.
Ensuring font consistency in specialized embedded software environments.
Troubleshooting font rendering issues in older web-based applications.

Frequently asked questions

No, the visual rendering and metadata of the font remain perfectly intact.

Because WOFF2 uses a more efficient compression algorithm (Brotli), switching to the older WOFF format typically results in a slight increase in file size.
