Many games, such as The Sims and Civilization 4, use DDS files to create the textures you see in landscapes. Although there are plug-ins you can download to allow you to resize DDS files, they are typically program-specific and may only work with one image editing program. The easiest way to resize DDS files is by converting them to JPG format, resizing them with any available image editor and converting them back to DDS.

Step 1

Download and install a DDS to JPG conversion program from the Internet (see Resources).

Step 2

Double-click the downloaded program to launch it. Press the "File to Convert" button and select your DDS file from the pop-up window. Press "OK." Select the "Convert To" drop-down menu and select "JPG." Press "Convert."

Step 3

Open a image editing program, such as Photoshop, Preview or Paintshop Pro. Press the "File" button and select "Open." Browse through the pop-up window until you locate the recently converted file. Highlight the JPG file and press "OK."

Step 4

Click on the "Image" menu and scroll to "Image Size." In some programs, this will say "Image Properties" or "Resize." Click on the box next to "Constrain Proportions" and enter a new pixel size in the "Height" box. The width size will automatically change. Press "Apply Changes."

Step 5

Save the image by pressing the "File" menu and scrolling to "Save." Export the image by pressing the "File" menu and scrolling to "Export." Select "JPG" under file type and enter a name in the text field.

Step 6

Return to the file conversion program. Press the "File to Convert" button and select your JPG file from the pop-up window. Press "OK." Select the "Convert To" drop-down menu and select "DDS." Press "Convert."
