Convert image files with our easy-to-use and free tool. Our tool lets you upload a DDS (DirectDraw Surface) file and, from this, create a new image saved in the EXR (OpenEXR) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple DDS image files; up to 25 files at a time can be converted.
Along with converting DDS image files to EXR, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available within the Options tab. Along with grayscale, you can also mirror or flip the image if needed. For single DDS file uploads, you will also see options to resize and rotate your image.
Here are two simple steps to convert your DDS to EXR.
First click the "Upload..." button, select your DDS file to upload. Select any configuration options. When the DDS to EXR conversion has completed, you can download your EXR file straight away.
We aim to process all DDS to EXR conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the DDS file you submit to us. The resulting EXR file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our DDS to EXR tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our DDS conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes! Our DDS tool supports full batch conversions. You can upload up to 25 and DDS files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the EXR files individually or download them all in a single ZIP file.

The DDS file format was introduced by Microsoft in 1999 and intended to be its standard image format for the DirectX 7 3D graphics API. The format is used to store textures for use within 3D graphics and game environments and can be compressed or uncompressed.
The compression algorithm used by DDS was the previously proprietary S3 texture compression, which could reduce the image file size and was easy for the GPU to decompress in real-time. The format is still used, and there are some third-party image editors that are compatible with it.

The EXR file format (OpenEXR) is an open-source and free image file format developed by Industrial Light & Magic in 1999. The format was originally developed to be a multi-channel, high-dynamic range raster image file format, which has evolved to include additional features over the years.
The format stores binary image data that can be either a 32-bit integer, a 16-bit integer, or a 32-bit floating point, which can also be compressed via a lossy or non-lossy compression method. The OpenEXR library is freely available to help developers implement the format in their applications.
