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 color, 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.

FBX files are an open 3D file format developed by Autodesk for use with their Maya and 3Ds Max applications. An FBX file may contain any number of 3D objects, their associated geometry, materials, textures, animations, and more, all within a single convenient package.
The content of an FBX file is a mix of binary and ASCII text, producing a format that is both human-readable and compact. Due to their compact size, ease of use, and widespread support, FBX files are a popular choice for creating 3D animations and are also a staple in the videogame development scene.
The development of the FBX format continues to this day, with new features being included in each release. Along with being used within Autodesk's own editing solutions, FBX files can also be opened and edited in other popular 3D modeling applications, such as Blender.
