TXTZ to GZ Converter
Processing entirely on your device — large files may take a moment.
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 a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip.
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 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 GZ format
A .gz file is one file squeezed by gzip — not an archive. kernel.org tarballs are “tar inside gz”, but plenty of logs, JSON dumps and CSV exports travel as plain .gz. Opening one means decompressing it back to the original bytes.
Repacking into ZIP or TAR gives the decompressed file a container that every GUI tool opens without a second thought.
+Strengths
- ✓Everywhere on Linux and macOS
- ✓Fast, well-understood compression
- ✓Streams natively from any tool
!Limitations
- −Single file only — no directory tree
- −No encryption or integrity metadata

Frequently asked questions
Is this TXTZ to GZ 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 GZ?
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 TXTZ archive modified?
No. Contents are unpacked in memory and repacked into GZ 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.
