Convert 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/use within image file editors or use for high definition printing applications. Our conversion tool can also batch convert multiple BMP image files, up to 25 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 greyscale filter to the image. These additional options are available within the Options tab. Along with Greyscale, you can also mirror/flip the image if needed. For single BMP file uploads you will also see options to resize and rotate your image.
Here are 2 simple steps to convert your BMP to DDS.
First click the "Upload..." button, select your BMP file to upload. Select 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 deleted 15 minutes after upload and the download link will expire after this time.
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 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 BMP tool supports full batch conversions. You can upload up to 25 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.
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 colour depths ranging from monocrome 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 my Microsoft in 1999 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 down and was easy for the GPU to decompress in real-time. The format is still used and there are some 3rd party image editors that are compatible with the format.
