How to convert WBMP to DDS

  1. Drop your .wbmp files above, or click Upload Files. You can add many files at once.
  2. DDS is already selected as the output. Open the settings (gear icon) to fine-tune the result.
  3. Click Convert All. ImageMagick runs inside your browser through WebAssembly; nothing is uploaded.
  4. Download your .dds files as soon as each one finishes.

What to know about WBMP to DDS conversion

  • DDS uses lossy compression, so files are usually much smaller than WBMP. Use the quality slider to balance size and detail.
  • DDS is best for GPU-compressed textures for games, and opens in game engines, DirectX tools and texture editors.

Frequently asked questions

Is it safe to convert WBMP to DDS here?

Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.

Is there a file size limit?

There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.

Can I convert several WBMP files at once?

Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
