WOFF2 to GZ Converter
Processing entirely on your device — large files may take a moment.
Web Open Font Format 2 and Gzip Compressed File exist for different jobs: 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. Unpack a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 GZ format
A .gz file is one file squeezed by gzip — not an archive. kernel.org tarballs are “tar inside gz”, but plenty of logs, JSON dumps and CSV exports travel as plain .gz. Opening one means decompressing it back to the original bytes.
Repacking into ZIP or TAR gives the decompressed file a container that every GUI tool opens without a second thought.
+Strengths
- ✓Everywhere on Linux and macOS
- ✓Fast, well-understood compression
- ✓Streams natively from any tool
!Limitations
- −Single file only — no directory tree
- −No encryption or integrity metadata
Why convert WOFF2 to GZ?
Converting makes sense where the strengths of GZ meet what WOFF2 cannot give you. Everywhere on Linux and macOS Meanwhile Not installable on desktop directly One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this WOFF2 to GZ 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 GZ?
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.
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.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
