Free, private, in-browser PNG/JPG → DDS (DirectDraw Surface). Supports DXT1/DXT5 compression for games like The Sims 3. No uploads.

For The Sims 3: Use DXT5 compression with power-of-two dimensions and mipmaps enabled.
ConvertResize's Image to DDS tool converts PNG or JPG images into DDS (DirectDraw Surface) textures directly in your browser. No registration and no uploads—everything runs locally for privacy.
DDS is widely used in games and 3D engines. This tool helps you prepare textures with power-of-two sizing, mipmaps, and DXT compression so they work correctly in games like The Sims 3, Source engine games, and more.
Supports DXT1 (BC1) for opaque textures and DXT5 (BC3) for textures with transparency. Both formats are GPU-compressed for fast loading and lower VRAM usage.
DDS (DirectDraw Surface) is a texture format commonly used in games and 3D engines. It can store 2D images, mipmaps, and cube maps in a GPU-friendly layout.
Why convert PNG or JPG to DDS?Many games and engines expect textures in DDS. DDS supports mipmaps, power-of-two sizes, and GPU compression for better performance.
Which compression should I use for The Sims 3?Use DXT5 for textures with transparency (like clothing, hair) or DXT1 for fully opaque textures. Both work with Sims 3. Make sure power-of-two and mipmaps are enabled.
Does this tool upload my images?No. The conversion runs entirely in your browser. Your files never leave your device.
What does "Make power-of-two" mean?Some engines (especially older ones) require dimensions like 256×256, 512×512, 1024×1024. This option rounds each dimension down to the nearest power-of-two for compatibility.
What does "Generate mipmaps" do?Mipmaps are automatically generated, smaller versions of your texture used when an object is far away. They reduce shimmering, improve visual quality, and can improve performance.
What's the difference between DXT1 and DXT5?DXT1 (BC1) compresses to 4 bits per pixel with no alpha transparency—best for opaque textures. DXT5 (BC3) uses 8 bits per pixel and preserves full alpha—use this for anything with transparency.
What does "Max Width" do?Scales the image down to a maximum width while keeping aspect ratio. Useful for large source images that you want to optimize for VRAM and performance.
Can I use this for normal images?DDS is primarily for games/3D. For everyday sharing and editing, PNG or JPG is usually better.
Image won't load? Make sure it's PNG, JPG, or WebP and not corrupted.
Sims 3 texture not showing? Make sure you're using DXT5 or DXT1 compression, power-of-two dimensions, and mipmaps. Also verify the texture path in your package file is correct.
Looks blurry? Turn off Max Width and re-export at original size, or generate mipmaps for better distance rendering.
Transparency not working? Use DXT5 compression instead of DXT1.
