FBX Texture Compression

Yes, the download stays FBX. If the model uses separate texture files, the output is a ZIP containing the optimized FBX and its maps, so you can drop it straight back into Maya, Blender, 3ds Max, or your game engine without re-exporting.

The output is a ZIP archive containing the optimized FBX and the compressed texture files. Relative references are preserved, so the FBX finds its maps as soon as you extract the archive. Keep the folder structure intact when you move or share it.

Common bitmap formats such as PNG, JPEG, WebP, BMP, TGA, and GIF are supported. The output format is set by the Texture Format setting (WebP/JPEG/PNG): WebP gives the best size/quality balance for web, PNG preserves alpha and detail, JPEG suits photo-like diffuse maps.

No. Only the texture bitmaps are resized and re-encoded; animation curves, skeletons, blend shapes, and geometry are exported unchanged. The FBX keeps the same structure, so nothing needs to be re-rigged or re-animated.

Embedded textures are re-encoded in place inside the FBX. External textures are re-encoded and delivered alongside the FBX in the ZIP, with references rewritten to the new files. In both cases the optimized FBX stays fully usable.

Yes. The output is a standard FBX with the same hierarchy, materials, and texture references, so it imports into Maya, 3ds Max, Blender, Unity, and Unreal without conversion.

The tool compresses textures in FBX 6.1 (FileVersion 6100) and newer files, ASCII or binary. Files older than 6.1 fail during parsing because their structure is different. Update them by re-exporting from modern 3D software, then compress here.
