OBJ to GZ Converter
Processing entirely on your device — large files may take a moment.
Unpack a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip. If your files are still in OBJ format, this page is the shortcut: OBJ is the veteran plain-text 3D format from Wavefront: vertices, faces and texture coordinates in a human-readable file that almost every 3D package imports.
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 OBJ format
OBJ (Wavefront, 1990s) is the veteran of 3D model exchange: a text file of vertices, UV coordinates and faces, optionally paired with an MTL material file and texture images. It predates every modern pipeline yet still opens everywhere, which keeps it as the default export of modeling tutorials, asset stores and scan software.
It is static by design — no animation, no rigging, no scene hierarchy beyond groups — and MTL's habit of referencing textures by relative path means a lonely .obj file often shows up untextured. For static meshes with appearance, it remains a dependable common ground.
+Strengths
- ✓Opens in every 3D application, old and new
- ✓Text-readable and easy to generate programmatically
- ✓Carries UVs and materials via MTL
!Limitations
- −No animation, rigging or hierarchy
- −Texture references break when files travel alone
- −Text format is bulky for dense meshes
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 OBJ to GZ?
There is a concrete reason this conversion exists: No animation, rigging or hierarchy 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 OBJ 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 OBJ 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 OBJ 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.
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 OBJ file.
