"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

SPU to DDS Conversion: FAQ

What are SPU files?

An SPU file contains an image created or edited using an image processor created for Atari computers. The program was called Spectrum and could support images storing up to 512 colors. The Atari brand was one of the first ones to gain an important share of the home users market, but its computers have now been discontinued for over 2 decades, so SPU files are uncommon and obsolete.

What are DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications. DDS is a container file and can be decompressed using a graphics processing unit (GPU).
