WOFF2 to XZ Converter
Processing entirely on your device — large files may take a moment.
Unpack XZ into ZIP/TAR for tools that cannot read LZMA2. If your files are still in WOFF2 format, this page is the shortcut: WOFF2 is the compressed web font format all modern browsers require. It typically shrinks TTF/OTF files by 50–70%, which is why @font-face rules expect it.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the WOFF2 format
WOFF2 (W3C, 2014) is the current standard of web fonts: the same TTF/OTF outlines compressed with Brotli, typically 30% smaller than WOFF and dramatically smaller than raw fonts, plus a table-transform optimization that shrinks glyf data further. Every browser since 2016 decodes it; no modern site ships anything else.
It is strictly a web container — you cannot install a WOFF2 into the OS directly — so the workflow is one-way: desktop font (TTF/OTF) converts to WOFF2 for the site, while the source file stays for design tools. Pair it with `font-display` and subsetting for maximum loading speed.
+Strengths
- ✓Smallest web font format (Brotli + transforms)
- ✓Universal modern browser support
- ✓Works with both TTF and OTF outlines
!Limitations
- −Not installable on desktop directly
- −No support in IE-era browsers
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert WOFF2 to XZ?
Think of it as moving your file to the container that fits the job. Not installable on desktop directly XZ works differently: Highest common ratio If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this WOFF2 to XZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WOFF2 to XZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are the files inside my WOFF2 archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the WOFF2 file.
