DDS File Viewer

View DirectDraw Surface textures online with metadata, mipmaps, hex inspection, and structure analysis - all in your browser. Just need to convert? Use the DDS to PNG Converter for batch export. Need to analyze other formats? Try our RAW File Viewer, PSD Analyzer, or SVG Viewer. For deeper image analysis use the PNG Analyzer, JPG Analyzer, or WebP Analyzer.

How to View DDS Files

  1. Upload your DDS file by dragging it onto the upload area, or click to browse your device.
  2. View the texture in the Preview tab. Zoom in or open fullscreen for pixel-perfect inspection.
  3. Browse mipmaps using the Mip selector in the toolbar to see how the texture scales down.
  4. Examine metadata in the Info tab, inspect raw bytes in Hex, or explore the file Structure.
  5. Export a single mipmap as PNG, or use Export All as ZIP for the full mipmap chain. For batch conversion of many DDS files, use the DDS to PNG Converter instead.

Looking for the reverse direction? Use the PNG to ICO converter for icon files, or our Image Converters hub for other formats. For game asset workflows, the PSD Analyzer and SVG Viewer handle layered and vector sources.

About the DDS Format

DDS (DirectDraw Surface) is a container format created by Microsoft for storing GPU-ready textures and cubic environment maps. Originally built for DirectX, it has become the de-facto standard for game engines like Unreal, Unity, Source, and CryEngine because compressed DDS textures upload straight to video memory without decompression - dramatically reducing load times and VRAM usage compared to PNG or JPEG.

GPU-native compressed block formats (DXT, BC1-BC7)
Built-in mipmap chain support
Cubemaps and volume (3D) textures
DX10 extended formats (BC6H HDR, BC7 high-quality)

Features

Texture Preview

View DDS textures with zoom (25-400%), pan, fullscreen, and transparency checkerboard.

Mipmap Browsing

Step through every mipmap level to see how the texture scales for distant rendering.

Hex Inspector

Paginated hex viewer with offset display, ASCII column, and byte/text pattern search.

Structure View

Expandable breakdown of the DDS header, pixel format, caps, DX10 header, and each mipmap.

PNG Export

Save the current mipmap as a standard PNG. Use Export All as ZIP for the full chain.

Private by Design

Everything runs in your browser. Files never reach our servers - safe for unreleased game assets.

Supported Formats

DXT1 / BC1 Compressed

4:1 compression with optional 1-bit alpha. Best for opaque or sharp-cutout textures.

DXT3 / BC2 Compressed

4:1 compression with explicit 4-bit alpha. Good for sharp alpha edges like foliage.

DXT5 / BC3 Compressed

4:1 compression with interpolated 8-bit alpha. Best for smooth transparency.

BC4 / ATI1 Compressed

Single-channel compression. Ideal for height maps, roughness, and grayscale masks.

BC5 / ATI2 Compressed

Two-channel compression. The go-to format for normal maps (RG).

RGB / RGBA Uncompressed

RGB, RGBA, BGRA, BGR, and luminance formats with arbitrary bit masks.

Frequently Asked Questions

DDS (DirectDraw Surface) is a texture container created by Microsoft for DirectX. It stores GPU-compressed textures (DXT, BC formats) that load directly into video memory, making it the standard format for game development. For other game asset formats, try our File Viewers hub.

Mipmaps are pre-calculated, progressively smaller versions of a texture - each level is half the size of the previous one. They improve rendering performance and reduce aliasing when textures are viewed from a distance. Most game DDS files include a full mipmap chain.

DXT (DirectX Texture Compression) and BC (Block Compression) are the same family of algorithms under different names. BC1 = DXT1, BC2 = DXT3, BC3 = DXT5. BC4-BC7 are newer formats introduced with DirectX 10/11 that offer better quality and specialized use cases like normal maps (BC5) and HDR (BC6H).

Yes - your files are completely safe. All DDS parsing and rendering happens locally in your browser using JavaScript. Files are never uploaded to a server, which makes this viewer suitable for unreleased game assets and confidential prototypes.

Some DDS formats are not fully decodable in JavaScript. We fully support DXT1, DXT3, DXT5, BC4, BC5, and common uncompressed formats. BC6H and BC7 have partial support - if the preview falls back to a checkerboard pattern, switch to the Info or Hex tab to inspect the metadata. Still having trouble? Please contact us and we'll be happy to help!

Yes - use the Export PNG button to save the current mipmap level as a standard PNG. For multi-mipmap DDS files, Export All as ZIP downloads every level packaged with a README. If you need to convert several DDS files at once, use the dedicated DDS to PNG Converter - it handles batch upload, alpha preservation, and auto-bundles the output as a ZIP. To convert in the opposite direction, check our Image Converters.
