EOT to XZ Converter
Processing entirely on your device — large files may take a moment.
EOT is Microsoft's web font format for IE4-IE8 — a TTF wrapped in a header with embedding permissions. The raw TTF rides at the tail of the file. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the EOT format
EOT (Embedded OpenType) is Microsoft's answer to web fonts from 1997: a TTF wrapped in a header carrying embedding permissions, root-string domain locks and a URI table — designed so foundries could license fonts for the web without giving away the raw file. IE4 through IE8 required it.
The actual sfnt rides unchanged at the tail of the file, so extraction is a pure slice: read FontDataSize from the header, take that many bytes from the end, and you have a TTF every modern browser accepts.
+Strengths
- ✓Carries embedding-permission metadata
- ✓Lossless TTF recovery from the tail
- ✓Required reading for legacy IE archives
!Limitations
- −Dead format — no modern browser loads it
- −Header variants (compression flags) exist
- −Root-string locks are trivially stripped
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 EOT to XZ?
Converting makes sense where the strengths of XZ meet what EOT cannot give you. Highest common ratio Meanwhile Dead format — no modern browser loads it One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this EOT 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 EOT 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.
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.
Are the files inside my EOT 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.
