WebP to DDS Converter
Convert WebP to DDS in your browser. WebP files usually come from websites, Chrome's Save image as, CDNs and Android apps; 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 WebP to DDS
- 1
Add your WebP 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.
Why use Aback Images for webp to dds
Where the DDS goes next
DDS opens in game engines, Visual Studio, Paint.NET, GIMP, NVIDIA and Intel texture tools.
DDS next to WebP
The DDS is written uncompressed, so expect it to be several times larger than the WebP, which stores lossy VP8 coding or lossless VP8L.
No new artefacts
WebP is already lossy, since it stores lossy VP8 coding or lossless VP8L; the DDS keeps the decoded pixels uncompressed, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
WebP vs DDS
What changes from WebP to DDS
Encoding: the WebP uses lossy VP8 coding or lossless VP8L; 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 bits per channel in the WebP; DDS allows 8 bits per channel for common texture formats, and the DDS written here has 8 bits per channel.
Colour: RGB; lossy WebP stores colour at half resolution (4:2:0) in the WebP; DDS supports RGB(A); normal maps and packed masks store data rather than colour, written here as 8-bit sRGB.
Transparency: the WebP stores it as a separate alpha plane, available in lossy as well as lossless files; the DDS keeps it as alpha inside the compressed blocks (BC2, BC3, BC7) or a 1-bit cut-out (BC1).
Animation: ANMF frame chunks, each with its own delay and blending; the DDS holds one image, so only the first frame is converted.
Metadata: the WebP can carry EXIF, XMP and ICC chunks; 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 WebP
WebP is Google's web image format. It supports lossy and lossless compression, transparency and animation, and is typically 25 to 35 percent smaller than JPEG at the same visual quality.
A WebP is a RIFF file: 'RIFF', a length, 'WEBP', then chunks. A simple lossy file is one VP8 chunk and a lossless one is VP8L; the extended VP8X header announces alpha, animation, ICC, EXIF or XMP chunks.
WebP files usually come from websites, Chrome's Save image as, CDNs and Android apps.
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 WebP to DDS makes sense
DDS is the better choice for game textures and mods, while WebP suits images on websites and in apps.
DDS strengths: Loads straight into GPU memory; Mipmaps included. Drawbacks to weigh: Not viewable outside game tools; Lossy block compression.
Limitations
- WebP images saved from websites are often already resized and compressed for the page, so the result cannot be sharper than that copy.
- 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 WebP to DDS lose quality?
DDS is written uncompressed, so the pixels are stored exactly as decoded. Artefacts already in the WebP stay, but nothing new is lost.
Is transparency kept in the DDS?
Yes. WebP stores it as a separate alpha plane, available in lossy as well as lossless files, and the DDS is written with an alpha channel, so transparent areas stay transparent.
Will my animated WebP stay animated?
No. DDS holds a single image, so only the first frame is kept. Convert to animated WebP, APNG or GIF to keep the motion, or export every frame with the GIF Frame Extractor.
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.
