File format information for PNG and GLB

Extension	PNG
Full Name	Portable Network Graphics
Type	Image
Mime Type	image/png
Format	Binary
Opens With	Paint.Net, Photoshop

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colors down to 256 or 16 colors to help reduce the file size of the PNG.

Extension	GLB
Full Name	Graphics Language Transmission Format
Type	3D Model
Mime Type	model/gltf-binary
Format	Binary
Opens With	Blender, MeshLab

GLB files are the binary equivalent of the GLTF 3D file format developed and maintained by the Khronos Group. GLB files are designed to be an open and expandable 3D format that can store 3D graphics and their assets, such as textures, animations, and more.

The content of a GLB file is binary and enables highly efficient storage and transmission of 3D data. This efficiency of size, along with its ability to store all the associated assets in the same file, has made GLB files one of the preferred formats for use within 3D web content and other applications.

Due to their open format, GLB files are widely supported by 3D editing software. The format has gained traction amongst videogame developers and other 3D artists as a primary means of exchanging 3D data between different applications.

Information for converting from PNG to GLB

Our PNG converter will convert your PNG file to a 3D model using the Heightmap process, whereby 2D pixels, based on their luminosity, are converted into 3D space to create a full 3D GLB model ready for download for further processing in your favorite 3D editing package or for printing on a 3D printer.
