GLB to TAR Converter
Processing entirely on your device — large files may take a moment.
TAR preserves the exact file tree and permissions that Linux tooling expects. If your files are still in GLB format, this page is the shortcut: GLB is the compact binary form of glTF — "the JPEG of 3D": one file carrying geometry, materials and textures, made for the web, AR and game engines.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the GLB format
GLB is the binary form of glTF 2.0 — the format the Khronos Group designed as “JPEG of 3D”. One self-contained file carries geometry, a full scene hierarchy, PBR materials with textures, skeletal animation and morph targets. It is the native asset format of three.js, Unity, Unreal, Blender and WebXR.
Converting to GLB is usually the upgrade path from OBJ/STL: materials become physically based and embedded, and scenes become portable in a single file. One honest caveat: Draco-compressed GLBs save space but many loaders need explicit decoder setup — plain GLB plays everywhere unconditionally.
+Strengths
- ✓PBR materials, hierarchy and animation in one file
- ✓The web/AR standard — loads natively in three.js
- ✓Compact binary with texture embedding
!Limitations
- −Mesh-only: no CAD solids or NURBS
- −Older niche tools may not know glTF
About the TAR format
TAR (tape archive) is Unix's fifty-year-old answer to bundling: it concatenates files with headers into a single stream, preserving POSIX permissions, ownership and symlinks — but compressing nothing. It is the container half of the classic .tar.gz pairing and the native format of Linux source trees and backups.
Being pure bundling, TAR pairs with a compressor: gzip (the classic), bzip2, zstd. Alone, a TAR is the same size as its contents. Windows 10+ ships bsdtar, so even Windows can unpack it now — permissions aside, where NTFS has no room to be faithful.
+Strengths
- ✓Preserves Unix permissions and symlinks
- ✓Streamable: works over pipes and tapes
- ✓The standard of Linux distribution and backup
!Limitations
- −No compression by itself
- −No built-in encryption
- −Permissions meaningless on Windows filesystems
Why convert GLB to TAR?
Converting makes sense where the strengths of TAR meet what GLB cannot give you. Preserves Unix permissions and symlinks Meanwhile Mesh-only: no CAD solids or NURBS One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this GLB to TAR 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.
Does the scale or orientation of the model change?
Vertex data is converted as-is. Formats without a unit system (like STL) are interpreted as millimeters by most 3D-printing tools — scale before converting if your model uses different units.
How large can the GLB 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.
