XYZ to GZ Converter
Processing entirely on your device — large files may take a moment.
XYZ is the plain-text point cloud format: one "X Y Z" triple per line, comments with #. Every GIS, molecular-chemistry and 3D-scanning tool can read it, which makes it the lowest common denominator of spatial data. 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 XYZ format
XYZ is the plain-text point cloud format — one 'X Y Z' triple per line, '#' comments allowed. Molecular chemistry dumps, LiDAR exports and 3D-scanner output all land in XYZ because every tool can read it.
Conversion is a faithful column mapping: the first three numeric columns become X/Y/Z and any extra columns are preserved, so nothing is lost going to CSV or back.
+Strengths
- ✓The lowest common denominator of point data
- ✓Human-readable, diff-friendly
- ✓Every GIS/3D tool imports it
!Limitations
- −No rate, scale or projection metadata
- −Large files as plain text
- −No colour/normal standard
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
Why convert XYZ to GZ?
There is a concrete reason this conversion exists: No rate, scale or projection metadata GZ sidesteps that — Everywhere on Linux and macOS If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this XYZ 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 XYZ 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.
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 XYZ file.
Are the files inside my XYZ 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.
