OBJ to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
TAR.GZ is what open-source projects and Linux servers expect to receive. 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 TAR.GZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
!Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)
Why convert OBJ to TAR.GZ?
Converting makes sense where the strengths of TAR.GZ meet what OBJ cannot give you. Universally understood on Unix-like systems Meanwhile No animation, rigging or hierarchy One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this OBJ to TAR.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.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
How large can the OBJ file be?
Everything runs on your device, so memory is the only ceiling. Dense meshes with millions of triangles convert fine on a desktop computer, just over a slightly longer coffee break.
Will my TAR.GZ model keep its colors and textures?
Only if TAR.GZ can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
