GLB → GLTF: unpack a single file into editable assets.
or click to browse, paste supported
GLB files bundle models, textures, and materials into one package, which prevents editing individual parts. This tool unpacks a GLB into separate GLTF files: texture images, geometry data, and material definitions become standalone assets. You can then open the GLTF in modeling software and replace or adjust each element independently, without being limited by the packed format.
Separated export downloads a ZIP archive with the main .gltf file, model data (.bin), and separate texture images, ideal for editing resources individually. Embedded export downloads a single .gltf file with all resources inlined, convenient for single-file distribution but larger and less convenient for editing textures. You can switch modes in the conversion settings.
In separated mode, you get a ZIP containing the .gltf file, .bin model data, and texture images (.png/.jpg) linked by relative paths. In embedded mode, you get a single .gltf file with everything inlined, no extra files needed.
Yes, use the GLTF to GLB tool on this site to repack the multiple files into a single GLB file. If you have an embedded single-file GLTF, unpack it to separated resources first, or upload that file directly for repacking.
Texture images keep their original format, typically PNG or JPG. If the original GLB uses compressed textures like KTX2, they are converted to standard PNG so you can edit them easily.
Yes. Geometry, materials, textures, and animations are all kept; the conversion only changes the packaging from a single binary file to separate resources. The only exception: compressed textures such as KTX2 are converted to standard PNG for broad compatibility.
The .gltf file will still load the geometry, but materials will appear without textures, usually gray or default-shaded. Keep the whole unpacked folder together so the texture references resolve.
Y-upDetermines the 'up' axis of the exported model. Different 3D software uses different conventions. Selecting the wrong system may cause the model to lie on its side.
0°-180° – 180°Rotate the model around the X axis (degrees). Useful for correcting axis misalignment or print orientation.
0°-180° – 180°Rotate the model around the Y axis (degrees). Useful for correcting axis misalignment or print orientation.
0°-180° – 180°Rotate the model around the Z axis (degrees). Useful for correcting axis misalignment or print orientation.
Root node transformChoose how rotation is written to the exported model. Baking into vertices rewrites all vertex coordinates so every export format (including geometry-only formats such as STL and STEP) applies it consistently; root node transform keeps the original vertex coordinates, which is friendlier to animated or skinned models, but formats that ignore node transforms (such as STEP) won't apply the rotation.
SeparatedChoose how textures and buffers are organized in the output.
