How to Convert HEIF 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. HEIF, despite also using efficient compression, is built for photo storage and display rather than real-time GPU rendering, and game engines generally have no native HEIF support since it falls outside typical texture pipelines.

Converting a phone reference photo from HEIF to DDS is necessary when you want to use that image as an actual in-game texture, letting the GPU load and render it efficiently the way it's designed to handle DDS files specifically.

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 HEIF file.
3. Drag your HEIF file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to HEIF and the "To" format to DDS.
5. Click Convert. DDS files are written to the output folder, fully offline.
