| 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.

The STL file format is used for storing 3D models and is a common format for distributing 3D printable models. STL files emerged in the 1980s as a format for storing a 3D mesh as a simple list of triangles. Due to its age and simplistic format, it has gained widespread support within 3D modeling and CAD applications.
As a result of the simple file format and its widespread support amongst 3D editors, the STL format has found itself as the format of choice for the distribution of 3D printable objects. There are many websites that offer 3D printing downloads in the STL format.
Mesh Geometry
As mentioned, STL files make use of a simple structure for containing the 3D mesh data. The 3D model is stored as a continuous list of triangles, with each triangle containing three vertices specifying the location in 3D space of the triangle, which, along with a single vector normal, is all that is required to render the model contained within the STL file. There are two formats of STL files: plain text and binary. When used with large and complex 3D models, the text format leads to very large file sizes and should be avoided, with the binary format offering more efficient storage of the mesh data.
