Convert your BMP to DDS image files with our easy-to-use and free tool. Our tool lets you upload a BMP (Bitmap Image File) file and, from this, create a new image saved in the DDS (DirectDraw Surface) 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 BMP image files; up to 200 files at a time can be converted.
Along with converting BMP image files to DDS, 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 by selecting the Options button. Along with grayscale, you can also mirror or flip the image if needed. For single BMP file uploads, you will also see options to resize and rotate your image.
This option can be used to rotate the image in 90° increments.
When selected, this option will flip the image vertically.
When selected, this option will mirror the image horizontally.
When checked, this will apply a black and white filter to the image, turning any color image into a black and white image.
When checked, this will apply a negative filter to the image, inverting all the colors within the image.
Add a sepia effect to your image using this option. The intensity can be adjusted using the slider control.

The BMP file format is a two-dimensional image file format popular on Microsoft Windows operating systems. Data is stored in the BMP file in a raster format, with pixels being represented using various color depths ranging from monochrome 1-bit per pixel (bpp) to full color 24-bits per pixel.
The format can also contain an image alpha channel, which is typically 8 bits per pixel in size and is used to describe image transparency. BMP files can also optionally be compressed using a lossless compression algorithm, meaning smaller files with no loss of image quality.

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.
Yes! Our BMP tool supports full batch conversions. You can upload up to 200 BMP files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the DDS files individually or download them all in a single ZIP file.
First click the "Upload..." button, and select your BMP file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the BMP to DDS conversion has completed, you can download your DDS file straight away.
We aim to process all BMP to DDS 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 BMP file you submit to us. The resulting DDS file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
No. All our conversion tools process your BMP file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted DDS file quickly.
Yes! Our BMP to DDS 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 BMP conversion tool please consider white-listing our website. When an Ad Blocker is enabled there are some conversion limits and some settings may not be available when using our tools. Processing/conversion and download times will also be longer.
Yes. When you have converted your BMP to DDS, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
