# Convert WOFF2 to WOFF.

> Repack WOFF2 as WOFF for legacy browsers — output grows.

Going from WOFF2 back to WOFF trades size for reach: zlib compresses less than Brotli, so expect the output to be 25–40% larger — **same font, older wrapper**. Useful when a legacy browser or an old toolchain insists on WOFF.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop TTF, OTF, WOFF, WOFF2 or EOT files anywhere on the page — or click to browse.
2. Pick the output format — the font tables are repackaged losslessly, never re-drawn.
3. Convert, then download each font on its own or the whole batch as a ZIP.

## The short list that still wants WOFF

Downgrading only makes sense when something in the chain cannot read WOFF2 — and that list is short, specific and shrinking.

| Environment | Why it needs WOFF |
| --- | --- |
| Internet Explorer 9–11 | WOFF2 support never shipped |
| Android 4.x stock browser & webviews | Frozen before Brotli existed |
| Old smart-TV & e-reader browsers | Engines forked around 2013–2015 |
| Strict CMS / email-builder allowlists | Upload validation predates WOFF2 |

## Budget for the growth

Expect the output to land 25–40% above the WOFF2 you started with — zlib simply cannot match Brotli on font tables. A 70 KB WOFF2 typically becomes a 90–100 KB WOFF. If both files end up on the same site, serve them as a pair in @font-face with the WOFF2 listed first, so only the browsers that truly need the bigger file ever download it. Upgrading in the other direction is [WOFF to WOFF2](https://compress-pro.com/woff-to-woff2).

## Frequently asked questions

### Why is the converted file bigger than my WOFF2?

Because WOFF uses zlib and WOFF2 uses Brotli, and Brotli simply compresses better. The font inside is identical — the older wrapper just costs 25–40% more bytes. That is the honest price of legacy compatibility.

### Who actually needs WOFF today?

Browsers that predate 2016 — IE9–11, old Android stock browsers, some embedded webviews — and the occasional tool or CMS that validates uploads against a WOFF-only allowlist.

### Am I allowed to convert this font?

Converting a font never changes its license. Many desktop licenses do not cover web embedding (and vice versa), so check yours before publishing a converted font. Fonts under the OFL or Apache licenses and fonts you made yourself are fine. Your file also never leaves your device — nothing is uploaded anywhere.

### Is it private?

Yes. The font is repackaged entirely in your browser — it is never uploaded, and the server does nothing but deliver this page. For licensed fonts that matters twice over: nothing is redistributed to any third party, and no copy lingers on a server afterwards. Want proof? Run one file through, switch your connection off, and run another — it still works.
