Muse to XZ Converter
Processing entirely on your device — large files may take a moment.
Muse is the minimal markup of Emacs Muse and Zim wiki — headings with asterisks, emphasis with underscores — designed for note-taking that stays readable for decades. 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 Muse format
Muse is the quietest markup in this list: an Emacs mode from the early 2000s (later adopted by the Zim desktop wiki) whose headings are leading asterisks, emphasis is underscore-wrapped, and that is most of the grammar. It was designed for personal notebooks that should still open cleanly in fifty years.
Muse files rarely hold anything more exotic than headings, lists and paragraphs, which makes conversion nearly lossless: Pandoc maps the small grammar onto Markdown, HTML or Word one-to-one. The only real work is deciding where the notes go next.
+Strengths
- ✓Extremely simple grammar — near-lossless conversion
- ✓Future-proof plain text
- ✓Native to Emacs Muse and Zim wiki users
!Limitations
- −Tiny ecosystem outside Emacs
- −No tables or footnotes worth mentioning
- −Effectively unmaintained as a format
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 Muse to XZ?
Converting makes sense where the strengths of XZ meet what Muse cannot give you. Highest common ratio Meanwhile Tiny ecosystem outside Emacs One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this Muse 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 Muse 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 Muse 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.
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.
