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.

GIF files have been around since the dawn of the internet and are a popular choice of format for storing images and animations. Images stored within a GIF file can be stored at low bits per pixel to reduce the size of the GIF file, leading to improved download speeds. Reducing the number of bits per pixel, if done correctly, can lead to no noticeable difference in image quality.
Along with static images, GIF files are also capable of storing short video or animation sequences. This capability has proved very popular, with animated GIFs being created and used on websites and social media. GIF files are also a popular format for storing and transmitting internet memes.
With newer and more capable formats such as PNG and WEBP taking over as the default standard for images and animations on the web, the GIF format is slowly declining in popularity. Support for GIF files within image editing software is still strong and will likely continue.
