| Full Name | High Efficiency Image File Format |
| Extension | HEIC |
| Type | Image |
| Mime Type | image/heic |
| Format | Binary |
An HEIC file is a relatively new image format created to offer greater quality and compression ratios than older formats such as JPG. HEIC has found widespread adoption among image editing software thanks to the use of the format by Apple on their phones and tablets.
Apple's adoption of the format was critical. Photos taken on Apple devices, such as their smart phones, being saved to the HEIC format has created a lot of interest in the format and a desire from third parties to support it.
Uses
As HEIC was designed to be a direct replacement for the JPG format, it shares the same uses; for example, it is best used for storing photographic images rather than logos and other images that require a lossless compression format.

| Type | 3D Model |
| Mime Type | text/plain |
| 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.
