Extract the files to a suitable folder and launch OnnxSharp.exe. The included onnxruntime.dll is the CPU version, so the conversion will take some time (1–2 minutes).
Load files by clicking the "Select File..." button in the sidebar or from the File menu. Based on the file type, the application performs the following:
Prepare the high-performance ONNX AI engine with a single click.
Go to the sidebar and use "Select..." to pick a local ONNX model, or click "Download from HuggingFace".
Once selected, the model is loaded into memory. You can switch between CPU and CUDA providers in the dropdown menu.
By default, OnnxSharp includes the CPU version of ONNX Runtime. For significantly faster reconstruction, you can enable NVIDIA GPU acceleration.
Download the CUDA-enabled ONNX Runtime DLLs matching your environment (e.g., for CUDA 12.x or 11.x).
Copy all files from the CUDA-enabled package (including onnxruntime.dll and providers) into the OnnxSharp application folder, overwriting the existing ones.
Restart the application. You should now be able to select NVIDIA CUDA in the Execution Provider menu without fallback warnings.
Process multiple images or entire folders at once using the Batch feature.
Click the "Batch Conversion" button in the sidebar or select it from the File menu. You can select input/output folders and manage naming conflicts (Overwrite/Rename) before starting the queue.
