How to Convert PNG to DDS Online in 3 Easy Steps

Turn PNG images into DDS (DirectDraw Surface) textures for game mods, 3D projects, or other apps that require DDS. Convert a single PNG or a whole texture set for free. BC1 (DXT1) keeps opaque textures compact, BC3 (DXT5) preserves transparency, and RGBA8 stores textures without compression. You can also generate mipmaps or resize textures to power-of-two dimensions.

Choose your PNG artwork

1Add your PNG files

Click “Select Images” or drag in your PNG files. Add a single image or a whole set of textures at once.

Convert the artwork to DDS

2Set up your DDS output

Keep DDS selected. Use Auto or pick BC3 (DXT5) to preserve transparency. Set mipmaps as needed, then click “Start Conversion.”

Download the texture files

3Save your DDS textures

Download a DDS file on its own or save the whole batch as a ZIP.

PNG to DDS for Game Textures and Mods

A single project can use everything from opaque wall textures to decals with soft edges. Convert your PNG artwork to DDS with compression and dimensions that suit each asset.

Convert PNG to DDS with Transparency

BC1 (DXT1) keeps opaque textures compact. BC3 (DXT5) preserves transparency in assets like foliage and decals. Uncompressed RGBA8 avoids block compression artifacts and produces larger files.

Prepare Textures for Different Viewing Distances

Mipmaps store smaller versions of a texture for use at different viewing distances. When enabled, this converter generates them only if both output dimensions are powers of two. If your project needs those dimensions, you can round the width and height up separately.

Batch Convert PNG Textures to DDS

When a set of textures shares the same compression and sizing settings, convert the PNGs together. You can download the finished DDS files as a single ZIP.

PNG to DDS FAQ

What does Auto compression choose for my PNG?
Auto checks whether the image has any transparent pixels. Fully opaque images use BC1 (DXT1), while images with transparency use BC3 (DXT5). If your game or engine requires a particular DDS format, select it directly.
Will a transparent PNG keep its soft edges in DDS?
BC3 (DXT5) keeps partial transparency, which works well for soft edges on decals or foliage. Uncompressed RGBA8 also keeps the alpha channel and produces a larger file.
Why is my DDS missing mipmaps even though I enabled them?
This converter generates mipmaps only when both output dimensions are powers of two. A 256 × 512 texture qualifies, but a 300 × 512 texture needs resizing first.
Will these DDS textures work in Skyrim or Fallout mods?
That depends on the game edition and the kind of texture you’re replacing. Use the original DDS as a guide for compression, dimensions, and mipmaps. Check how the replacement looks in the game before publishing your mod.
Can I keep my PNG’s original width and height?
Yes. The converter keeps the original dimensions by default. Power-of-two resizing rounds each side up separately. For example, a 300 × 500 image becomes 512 × 512, which changes its aspect ratio.
Can I convert a whole set of PNG textures in one batch?
Yes. A batch uses the same settings for each image, and you can save the DDS files individually or as a ZIP. Both single-file and batch conversion are free.

HiCompress PNG to DDS Converter Features

Automatic DDS Compression

Converting a mix of opaque and transparent artwork? Auto picks BC1 for fully opaque PNGs and BC3 for images with transparency.

Batch Convert PNG to DDS

Prepare a whole texture pack in one batch with shared settings. Download individual DDS files or save the full set as a ZIP.

BC1 (DXT1) and BC3 (DXT5) Compression

BC1 keeps opaque textures compact. BC3 keeps partial transparency for details like soft lettering edges and translucent decals.

Generate DDS Mipmaps

Mipmaps give 3D scenes smaller versions of a texture to use at a distance. You can include them when both output dimensions are powers of two.

Power-of-Two Texture Dimensions

Keep the original size or round the width and height up separately when your project needs dimensions such as 256 × 512.

Uncompressed RGBA8 DDS

Store color and transparency without block compression when its artifacts would be noticeable. RGBA8 files are larger than BC1 or BC3 files.
