DDS file information

Full NameDirectDraw Surface
Mime Typeimage/

DDS files are the native image file format used by Microsoft's Direct X gaming API, which was originally developed in the early 2000s as a means for game developers to store texture images in a standard format that are used in 3D game worlds.

The format was enhanced over the years to add lossy and lossless compression and other features applicable to 3D game development. The format has gained some modest support within image editing applications over the years; however, specialist image viewing software is needed to open and display DDS files on many devices.


The primary use for DDS files is in the realm of videogames, in particular those that run on Microsoft Windows-based machines such as PCs. DDS files are used to store imagery that is applied as textured materials to the surfaces of objects within 3D worlds; they can also be used in 2D applications.

Palette and Transparency Support

A DDS file supports both a 256-color palette mode and full-color 24-bit color. When using the palleted mode, the 256 colors chosen can be any color from the full 16.7 million possible colors. Transparency is also supported, with this capability being essential when using DDS files for 2D applications.

Compression Technology

The DDS format supports both lossy and lossless compression techniques, including the S3 Texture Compression (S3TC), which can be natively decompressed on PC graphics cards (GPU's).
