TSV to XZ Converter
Processing entirely on your device — large files may take a moment.
Tab-Separated Values and XZ Compressed File exist for different jobs: TSV (Tab-Separated Values) is CSV’s cousin that uses tab characters as separators — common in bioinformatics, data-warehouse exports and Excel clipboard data. 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 TSV format
TSV is CSV's tab-separated sibling: rows as lines, columns split by tabs, everything plain text. Its quiet superpower is the clipboard — copy a range in Excel or Sheets, paste into a text editor, and you are looking at TSV; paste it back and the grid restores. That round-trip makes it the Lingua franca of ad-hoc spreadsheet work.
The tab delimiter avoids CSV's comma-in-text quoting dance, at the price of being broken by any value that itself contains a tab — there is no standard quoting. Like CSV it is untyped, single-table, and happiest as a quick exchange or import format.
+Strengths
- ✓Round-trips through the clipboard with spreadsheets
- ✓No quoting rules to worry about
- ✓Columns align visually in monospace editors
!Limitations
- −A tab inside any value corrupts the file
- −Untyped and single-table like CSV
- −Some tools assume CSV only
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 TSV to XZ?
Think of it as moving your file to the container that fits the job. A tab inside any value corrupts the file XZ works differently: Highest common ratio If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this TSV 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.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
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.
Are the files inside my TSV 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.
