TXTZ to XZ Converter
Processing entirely on your device — large files may take a moment.
Zipped Text Ebook and XZ Compressed File exist for different jobs: TXTZ is a plain-text ebook packed in a zip — the lightest format that still travels as a single file, common for Palm-era and minimalist readers. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
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 TXTZ format
TXTZ is the minimal ebook: a plain-text file (often with a lightweight markup of blank-line-separated chapters) zipped into a single deliverable. Palm-era readers and minimalists favor it because nothing can break — there is nothing inside but text.
The converter unzips, detects chapter boundaries the same way it does for raw text, and hands you an EPUB or clean text — the zip exists only for transport.
+Strengths
- ✓Nothing to break — text only
- ✓Tiny files
- ✓Chapters rebuilt from blank-line structure
!Limitations
- −No images, no styling
- −Chapter detection is heuristic
- −Few reader apps accept it
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 TXTZ 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 TXTZ 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 TXTZ file.
Are the files inside my TXTZ 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.
