Convert your DDS file to QOI

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 QOI (Quite OK Image Format) 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 QOI, 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.

Upload a DDS

Click the "Upload a DDS File" button and select a DDS to upload. The maximum file size is 100MB.

Download your QOI

Click the download link once completed to receive your QOI file.

Rotation

This option can be used to rotate the image in 90° increments.

Flip Vertically

When selected, this option will flip the image vertically.

Mirror Horizontally

When selected, this option will mirror the image horizontally.

Greyscale Image

When checked, this will apply a grayscale filter to the image, turning any color image into a grayscale image.

Negative Image

When checked, this will apply a negative filter to the image, inverting all the colors within the image.

Description

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.

Description

The QOI file format is a modern image format capable of storing full color (32-bit) images in a compact format, with file sizes of QOI files similar to those of a PNG file.

QOI files are designed first and foremost with encoding and decoding speed in mind. It is many times faster to encode or decode an image into the QOI format than other formats, such as PNG.
