3D Model Texture Compression

The tool automatically detects and processes all texture maps in your model including diffuse/albedo maps, normal maps, roughness maps, metallic maps, ambient occlusion maps, and emissive maps.

WebP offers the best compression ratio for web use. JPEG is good for photographs/diffuse maps without transparency. PNG is best when you need lossless compression or alpha channel. Keep original if you don't want format conversion.

Normal maps are compressed using the same settings as other textures. For best results with normal maps, consider using PNG (lossless) or keeping the original format to avoid artifacts that could affect surface appearance.

For most web applications, 1024px or 2048px is sufficient. Going below 1024px may cause visible blurriness. The original size option preserves full resolution.

Currently all textures in the model are processed with the same settings (max size, format, quality). If you need per-texture control, you can use a tool like glTF-Transform CLI to configure individual textures manually.

KTX2 is ideal for real-time 3D applications like WebGL games or VR experiences where GPU decoding performance matters most. For general web viewing and sharing, WebP or JPEG offer better compatibility with standard image editors and are easier to preview.
