How do I convert WOFF2 to WOFF?

Add your WOFF2 file to the upload area above, then press Convert. The WOFF file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to WOFF reduce quality?

No. WOFF is a lossless format, so the conversion preserves exactly what is in your WOFF2 file. Note that it cannot recover detail that was already discarded when the WOFF2 was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 40 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

WOFF2 and WOFF explained

WOFF2 uses Brotli compression, producing web fonts roughly 30% smaller than WOFF. It is the format every current browser prefers.

WOFF wraps a TrueType or OpenType font with compression and metadata, specifically for delivery over the web.

Where WOFF2 files come from: Modern web font delivery.
Where WOFF is used: Web font services and site asset pipelines.

WOFF2 vs WOFF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

WOFF2 compared with WOFF
Property	Source	Target
Compression	Lossless	Lossless
Introduced	2014	2009
Browser support	All modern browsers.	All browsers including old ones.

WOFF2 is stronger at: The smallest web font format available. Supported by all current browsers. Directly reduces page load time.
WOFF is stronger at: Compressed for the web. Supported by every browser including very old ones. Carries licensing metadata.

Why convert WOFF2 to WOFF?

People make this switch when they run into the limits of WOFF2: desktop installation, or supporting very old browsers. WOFF is the better fit when you must support browsers from before roughly 2016.

WOFF2 limitations that prompt the switch: No support in browsers older than roughly 2016. Not installable as a desktop font.
What you give up: Around 30% larger than WOFF2. Superseded for any modern browser target.

What is preserved when converting WOFF2 to WOFF?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
