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 WebP file is a next-generation image file format designed for the web. It allows large and highly detailed photographic-quality images to be stored using a very small file size, making it an ideal format for use by websites where bandwidth comes at a premium.
It's aim is to replace other photographic formats, such as JPEG, by offering similar levels of compression and quality while offering a superior reduction in file size. As well as storing static images, the WEBP format can also store animations, making it a great alternative to the traditional animated GIF format.
As the WEBP format is still relatively new, support for it is best found in modern image editing applications or those that benefit from regular updates.
