TGA to DDS Converter
Convert TGA to DDS in your browser. TGA files usually come from game engines, 3D renderers and texture painting tools; DDS is the better fit for game textures and mods. You get an uncompressed 32-bit RGBA DDS texture with a single mip level, or DXT1 or DXT5 block compression if you choose it. Nothing is uploaded.

How to use TGA to DDS
- 1
Add your TGA files: drop them here, choose them, or paste from the clipboard.
- 2
Choose the DDS compression: none for an exact 32-bit texture, DXT1 or DXT5 for smaller GPU-ready files.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .dds files one at a time or together as a ZIP.

Where the DDS goes next
DDS opens in game engines, Visual Studio, Paint.NET, GIMP, NVIDIA and Intel texture tools.
DDS next to TGA
Neither format compresses much, so the DDS lands close to the TGA in size.
Written without a lossy pass
The DDS is written uncompressed, so the pixels decoded from the TGA arrive unchanged.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
TGA vs DDS
What changes from TGA to DDS
Encoding: the TGA uses uncompressed or run-length encoded (RLE); DDS uses block compression (BC1 to BC7, also called DXT) or uncompressed RGBA, and the download is an uncompressed 32-bit RGBA DDS texture with a single mip level, or DXT1 or DXT5 block compression if you choose it.
Bit depth: 8, 15, 16, 24 or 32 bits per pixel in the TGA; DDS allows 8 bits per channel for common texture formats, and the DDS written here has 8 bits per channel.
Colour: RGB, greyscale or a colour map in the TGA; DDS supports RGB(A); normal maps and packed masks store data rather than colour, written here as 8-bit sRGB.
Transparency: the TGA stores it as the fourth byte of each 32-bit pixel (or one bit in 16-bit files); the DDS keeps it as alpha inside the compressed blocks (BC2, BC3, BC7) or a 1-bit cut-out (BC1).
Metadata: the TGA can carry an image ID field and an optional extension area with author and date; DDS can carry a 128-byte header (plus a DX10 header) describing the pixel format, nothing about the picture, but nothing is copied across.
About TGA
TGA is a simple raster format still widely used for game textures and 3D rendering pipelines because it stores alpha channels reliably and loads fast.
A TGA has an 18-byte header (ID length, colour map type, image type 2 for true colour or 10 for RLE, origin, size, bits per pixel and a descriptor byte whose bits give the alpha depth and whether rows run top-down), then the pixels; version 2 files end with a 'TRUEVISION-XFILE' footer.
TGA files usually come from game engines, 3D renderers and texture painting tools.
About DDS
DDS is a GPU texture format used by DirectX games. It stores block-compressed textures (DXT/BC) and mipmaps that graphics cards decode directly.
A DDS file starts with 'DDS ' and a 124-byte header giving the size, mipmap count and pixel format: a FourCC such as DXT1 or DXT5, or 'DX10' followed by an extra header naming a DXGI format. The largest mipmap comes first.
When converting TGA to DDS makes sense
DDS is the better choice for game textures and mods, while TGA suits game textures and 3D software.
DDS strengths: Loads straight into GPU memory; Mipmaps included. Drawbacks to weigh: Not viewable outside game tools; Lossy block compression.
Limitations
- Some writers store rows bottom-up and some top-down; the descriptor byte says which, and the decoder follows it, so orientation is preserved.
- The DDS has a single mip level, so generate mipmaps in your engine or texture tool if it needs them.
- Uncompressed DDS textures take 4 bytes per pixel; DXT1 is an eighth of that and DXT5 a quarter, at the cost of lossy 4×4 block compression.

Frequently asked questions
Does converting TGA to DDS lose quality?
DDS is written uncompressed, so the pixels are stored exactly as decoded.
Is transparency kept in the DDS?
Yes. TGA stores it as the fourth byte of each 32-bit pixel (or one bit in 16-bit files), and the DDS is written with an alpha channel, so transparent areas stay transparent.
Which apps open DDS files?
Game engines, Visual Studio, Paint.NET, GIMP, NVIDIA and Intel texture tools. It does not open in web browsers.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
