How to Convert ICO to DDS

DDS is Microsoft's GPU-optimized texture format, built so graphics cards can read compressed texture data directly without a separate decompression step, which is why it's the standard format for DirectX games and engines like Unity and Unreal. Converting ICO to DDS is useful when an existing icon design needs to become an actual in-game UI texture, since DDS is the format those engines render most efficiently.

This conversion handles the decode and GPU-specific compression in one step, letting the resulting texture load and render the way the engine specifically expects DDS files to behave.

1. Install Batchify Image Converter and Resizer Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single ICO.
3. Drag your ICO file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to ICO and the "To" format to DDS.
5. Click Convert. DDS files are written to the output folder, fully offline.
