About this tool
For previewing textures, posting screenshots of them, or dropping them into a document, JPG is the convenient choice: small and viewable anywhere. The texture is decoded from its DXT/BC compression in your browser; transparent areas are flattened onto white, because JPG has no alpha channel.
About the formats: DDS (DirectDraw Surface) is the texture format game engines and modding tools use: Skyrim, Fallout, GTA, Unity, Unreal, and countless others. It stores GPU-ready, block-compressed pixels (DXT1/DXT5/BC7) together with a mipmap chain, which is exactly why ordinary image viewers and editors cannot open it without a plugin. JPG (JPEG) is a lossy format built for photographs. It compresses aggressively, produces small files, and opens on every device ever made, but it cannot store transparency and each re-save costs a little quality.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your DDS files into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click Convert to JPG and wait a moment.
- Download the results individually or all at once as a ZIP.
Frequently asked questions
Should I pick PNG or JPG for a DDS texture?
PNG if you plan to edit the texture or need its transparency; JPG for quick previews and sharing.
Which DDS formats can be opened?
DXT1, DXT3, DXT5 (BC1-BC3), ATI1/ATI2 (BC4/BC5), BC6H, BC7, and the common uncompressed layouts such as 32-bit BGRA/RGBA. Both classic and DX10-header DDS files work.
What about mipmaps, cubemaps, and texture arrays?
The full-size base level is converted. For cubemaps and arrays, the first face or layer is used.
Why does the transparency or color look strange?
Games often store non-color data in textures: specular or roughness in the alpha channel, or two-channel normal maps (BC5) that appear red and green. The conversion is correct; the texture simply was not a picture in the usual sense.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
