TXT to XZ Converter
Processing entirely on your device — large files may take a moment.
Plain Text and XZ Compressed File exist for different jobs: TXT is the simplest document format of all: just characters, readable by every program ever made, with zero formatting. 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 TXT format
TXT is the floor of computing: a sequence of characters and nothing else. No headings, no bold, no embedded images — and because there is nothing to interpret, every editor, terminal, programming language and operating system ever built opens one. Modern files are UTF-8; older ones may be GBK, Latin-1 or Shift-JIS, which is the only surprise plain text can still deliver.
Its limits are obvious — no formatting means no structure — yet that is exactly why TXT refuses to die: logs, notes, code, READMEs, config fragments and data dumps all live happily as plain text. When you need the content and not the styling, TXT is the lowest-friction answer there is.
+Strengths
- ✓Opens absolutely everywhere, including terminals
- ✓Tiny files, no parser, no corruption vectors
- ✓Perfect for logs, notes and machine-to-machine text
!Limitations
- −No formatting, structure or media whatsoever
- −Legacy encodings can garble non-English text
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

Frequently asked questions
Is this TXT 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 TXT 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 TXT 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 TXT file.
