TOML to XZ Converter
Processing entirely on your device — large files may take a moment.
TOML (Tom’s Obvious Minimal Language) is the config format of Rust’s Cargo, Python’s pyproject.toml and many modern tools — clearly typed, human-friendly key/value tables. 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 TOML format
TOML (Tom's Obvious Minimal Language, 2013) is config written for humans who read diffs: explicit key = value pairs, `[section]` tables, unambiguous types, and comments everywhere. Rust's Cargo, Python's pyproject.toml, and many modern build tools standardized on it exactly because there is no implicit typing and no indentation to get wrong.
The explicitness costs verbosity on deep structures — four levels of nesting in TOML is a stack of bracketed section headers, where YAML would just indent. For flat-to-medium project configuration it is close to ideal; for deeply nested data, JSON or YAML remain easier.
+Strengths
- ✓Unambiguous types and syntax
- ✓Comment-friendly and diff-friendly
- ✓Standard for Rust and Python project config
!Limitations
- −Deep nesting gets verbose fast
- −Rare in web APIs and serialization
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 TOML to XZ?
Converting makes sense where the strengths of XZ meet what TOML cannot give you. Highest common ratio Meanwhile Deep nesting gets verbose fast One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this TOML 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 TOML 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.
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 TOML 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.
