PNG to DDS Converter

This tool converts PNG images to DDS texture format online, targeting game developers and asset pipelines. It accepts a PNG input, applies a chosen DDS compression (DXT1, DXT3, or DXT5), and outputs a DDS file with optional mipmaps. The process is deterministic and suitable for DirectX-based engines. Conceptually, the PNG data is interpreted as a texture, then compressed in 4x4 pixel blocks according to the selected scheme, with optional alpha handling. The tool supports resizing prior to compression, and the mipmap chain can be generated to aid texture sampling at multiple distances. Use cases include preparing textures for Unity, Unreal, or custom engines where DDS is the preferred container. Unique value lies in an online, repeatable workflow that reduces the need for local tooling, while exposing control over compression mode and mipmapping to fit performance budgets. Core features include input validation for PNG format, support for DXT1/3/5, optional mipmaps, and output metadata that describes dimensions, format, and compression. Typical workflows involve validating textures in a build system, then distributing the DDS assets to the game asset bundle. The tool focuses on domain logic, data integrity, and output predictability, without UI concerns or marketing messaging.
