| Full Name | AV1 Image File Format |
| Extension | AVIF |
| Type | Image |
| Mime Type | image/avif |
| Format | Binary |
AVIF files are a re-imagination of the popular lossy compression image formats such as JPEG and aim to offer better compression ratios while delivering higher-quality results. Compared to the JPEG format, the AVIF format is still relatively new and has yet to gain widespread support among image viewing and editing applications.
With that said, support for AVIF files is growing and is now supported by the majority of web browsers, with support added in recently released versions.
Uses
Due to their high compression capabilities and support for transparency channels, AVIF files are becoming a popular alternative to both JPEG and PNG files, which makes them a perfect format for web based images and other similar applications.

| Format | Text |
An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.
As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.
Mesh Geometry
Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.
