How it works
Everything runs in your browser — your image is never uploaded. The tool builds the
tempdecal.wad and a preview, and you download the file to your computer.
What is tempdecal.wad?
A custom spray (decal) format used by GoldSrc games — Half-Life, Counter-Strike 1.6,
and Sven Co-op. By default these games ship only a few preset sprays; a
tempdecal.wad lets you spray any image you like, including full-color ones.
Where do I put the file?
Copy your tempdecal.wad into the folder shown for your game:
- Sven Co-op:
Sven Co-op\svencoop - Half-Life:
Half-Life\valve - Counter-Strike 1.6:
Half-Life\cstrike
To find your Game Folder, open Steam → Library, right-click the game and
choose Manage > Browse local files.
Recommended: set tempdecal.wad to read-only (right-click → Properties → check
Read-only) so the game can't overwrite your custom spray with a default one.
Sven Co-op
Enable custom sprays: launch the game → Options → Multiplayer → Advanced..., then under Graphics set Custom player sprays to Enabled.
Pick a Decal memory budget that matches your Sven Co-op texture cache:
- 2 MB cache — tightest fit, guaranteed to load on the smallest budget
- 4 MB cache — lighter budget
- 8 MB cache — recommended; works on Sven Co-op
- 16 MB cache — largest, only if your game supports it
Pixel-art sprays
To keep pixel art sharp instead of blurry, run this in the in-game console:
gl_texturemode GL_NEAREST_MIPMAP_LINEAR
(This tool also resamples with point sampling when the image has hard edges, which favors crispness.)
Supported image formats
PNG, JPEG, BMP — and generally any raster format your browser can load (except SVG).
