How to convert DDS to PNG
- 1
Add your DDS files
Drop one or many .dds files on the box, or click it to pick them. They are read on your device and never sent to a server.
- 2
Check the previews
Each file shows a preview with its format and size. Turn on "All mip levels" if you also want the smaller mipmaps as PNGs.
- 3
Download PNG or ZIP
Download one PNG, or all files at once as a ZIP. Cubemaps give one PNG per face, named posx, negx, posy, negy, posz and negz.
DDS formats supported
| Format | Also called | Typical use | Supported |

| BC3 | DXT5 (and DXT4) | Colour with smooth alpha | Yes |
| BC4 | ATI1 | One channel: height, roughness, masks | Yes, as greyscale |
| BC5 | ATI2, 3Dc | Two-channel normal maps | Yes, blue rebuilt as normal Z |
| BC7 | BPTC | High-quality colour and alpha | Yes |
| Uncompressed | A8R8G8B8, X8R8G8B8, R8G8B8A8, R8G8B8, R5G6B5, A1R5G5B5, A4R4G4B4, L8, A8L8, A8 | Lossless textures and UI art | Yes |

DDS viewer
Inspect one DDS file: zoom, R/G/B/A channels, every mip level and cubemap face.
PNG to DDS converter
Turn PNG, JPG or WebP into BC1, BC3, BC7 or uncompressed DDS, with mipmaps.
TGA to PNG converter
Convert TGA textures (8 to 32-bit, RLE) to PNG with alpha kept.
Texture a 3D model with AI
Upload a GLB, OBJ or FBX and describe the look; AI paints a new texture onto your model.

Frequently Asked Questions
No. The DDS decoder runs in your browser, so your textures stay on your device. That also means there is no queue and no file-count limit beyond your device memory; textures up to 8192x8192 pixels open.
BC1 (DXT1), BC2 (DXT3), BC3 (DXT5), BC4 (ATI1), BC5 (ATI2), BC7, and uncompressed formats such as A8R8G8B8, R8G8B8A8, R5G6B5 and L8, with old-style or DX10 headers. HDR formats (BC6H and float) are not supported yet; the tool tells you the exact format when it cannot open a file.
Yes. The PNG keeps the alpha values exactly as the DDS stores them, even where alpha holds other data such as a roughness or mask channel. Fully opaque textures are saved as RGB PNGs, which are smaller.
By default you get the full-size image (mip 0). Turn on "All mip levels" to get every mipmap as its own PNG. A cubemap gives six PNGs, one per face, and a texture array gives one PNG per slice.
BC5 stores only the red and green channels of a normal map. The converter rebuilds the blue channel from them, the way game engines do, so the PNG is a normal map you can use in Blender, Substance or our 3D tools.
