About this mod

A Paint.NET FileType plugin that supports BC7 and other modern DDS formats.

Permissions and credits
This plugin allows Paint.NET to load and save DDS files that use BC7 and other modern DDS formats.

The plugin is bundled with Paint.NET, but if you need the features from a newer version you can still install the plugin into the Paint.NET FileTypes folder.
The installed plugin will override the bundled version if it has higher version number.

The plugin supports loading and saving DDS files that contain single images and cube maps, texture arrays and volume maps are not supported.
If the file contains mipmaps only the main image will be loaded, the plugin has the option to generate mipmaps when saving.

Supported DDS Formats

The plugin can read most DDS formats, but only the following formats are supported when saving:


  • BC1 (Linear and sRGB)
  • BC2 (Linear and sRGB)
  • BC3 (Linear and sRGB)
  • BC4 (Unsigned)
  • BC5 (Signed and Unsigned)
  • BC6H (Unsigned 16-bit Float)
  • BC7 (Linear and sRGB)


  • R8G8B8A8 (Linear and sRGB)
  • R8 (Unsigned)
  • R8G8 (Signed and Unsigned)

  • B8G8R8A8 (Linear and sRGB)
  • B8G8R8X8 (Linear and sRGB)
  • B4G4R4A4
  • B5G5R5A1
  • B5G6R5

Legacy DirectX 9:

  • R8G8B8X8
  • B8G8R8
  • ATI1 (BC4 Unsigned)
  • ATI2 (BC5 Unsigned)
  • RXGB (A BC3/DXT5 variant used for normal maps)

Known Issues

  • DDS files that contain texture arrays or volume maps are not supported.
  • Manually editing mipmaps is not supported, but the plugin can generate them when saving.
  • You have to know the correct DDS format and options to use when saving an existing file, the plugin cannot automatically configure this information.
The best way to determine the DDS format of a file is by using the DirectXTex texdiag utility.


  • Close Paint.NET.
  • Place DdsFileTypePlus.dll, DdsFileTypePlusIO_ARM64.dll and DdsFileTypePlusIO_x64.dll into the Paint.NET FileTypes folder which is
    usually located in one the following locations depending on the Paint.NET version you have installed.

    Classic: C:\Program Files\Paint.NET\FileTypes
    Microsoft Store: Documents\ App Files\FileTypes
    <Paint.NET folder>\FileTypes

    3. Restart Paint.NET
