The Decal Tool is a single-use tool item. The Decal Tool can be used to spray a custom texture (or 'decal') on enabled items. Purchasing any item that the Decal Tool can be used on from the Mann Co. Store will also give players one free Decal Tool.

While using the tool the player will be guided through the steps to get their image onto the item. The file types accepted are:

.jpg
.bmp
.tga
.vtf

Oversized or odd aspect ratio images can be stretched or cropped to fit the 256x256 square. Depending upon the item the decal will be applied differently, check the specific item page to see a template for the most efficient decal templates. Once the decal has been chosen the image can be filtered using different options and finally applied to the item.
