Convert WOFF2 to WOFF
Convert a WOFF2 into a WOFF right here on the page. WOFF is a font packaged for websites, smaller than the desktop file it came from so pages load faster. Your file never leaves your computer.

- 4 Download the WOFF, or add more files and do the whole set in one go.
Why convert WOFF2 to WOFF

WOFF2 compared with WOFF
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | WOFF2 | WOFF |
|---|---|---|
| File extension | .woff2 | .woff |
| Colour depth | Brotli compression with a transformed glyf table | Per-table zlib compression over a TrueType or OpenType payload |
| Introduced | 2018 | 2009 |
| Developed by | Google, standardised by W3C | Mozilla, Type Supply and LettError, standardised by W3C |
Quality and what changes
Both sides are lossless, so every pixel survives the trip intact and converting back returns the same image. What changes is the size and what the file can carry: WOFF compresses the same data with a different algorithm, so the size can move in either direction.
- One WOFF limitation to keep in mind: superseded by WOFF2, which is around 30 percent smaller again.
Questions about WOFF2 to WOFF
Is my WOFF2 file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your WOFF2 is read straight from your own disk, converted on your machine and handed back as a WOFF. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several WOFF2 files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate WOFF downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
