The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.
As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular colour, transparency, and much more.
The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

When converting 3D model or mesh files using our OBJ converter, we will attempt to convert colour materials into a suitable format for use in the converted file.

A ZIP file is a compressed file container format that has been around for many years and has become a universal standard for compressing multiple files into a single package. Along with compressing individual files, ZIP files can also compress entire directory structures.
The compression algorithm of the ZIP format enables highly efficient compression of most file types, whether they be text, music, or images. ZIP files are a great way to group together and compress multiple files for easy storage and distribution.
As ZIP files have become a standard format for file compression, most operating systems and platforms are capable of creating and opening ZIP files without any additional software.
