QualityScaler-Go: local AI image and video upscaling

QualityScaler-Go is a free, open-source desktop application for restoring and enlarging images and videos on your own Windows or Linux computer. It uses Real-ESRGAN, BSRGAN, and CodeFormer; source media stays local instead of being uploaded to a cloud service.

What QualityScaler-Go processes

Choose individual images, videos, or folders for batch work. The video pipeline preserves the original audio and frame rate while it extracts frames, applies the selected model, and assembles the result. Use it for photo restoration, anime artwork, compressed footage, face enhancement, noise reduction, blur reduction, and 2x to 4x super-resolution.

Choose an edition for your hardware

TensorRT editions target supported NVIDIA GPUs for maximum throughput. ONNX CUDA editions use CUDA where TensorRT is unavailable, while ONNX CPU editions provide a no-GPU fallback. The application can automatically fall back when a preferred accelerator or model cannot run on the current machine.

Models and processing controls

Real-ESRGAN and BSRGAN provide general image restoration; CodeFormer can improve detected faces. The interface exposes model selection, scale, tile and VRAM-related controls, face enhancement, and memory or disk video-pipeline modes so that long videos can be balanced against available storage and GPU memory.

Before downloading

Review the installation requirements, edition guide, model descriptions, and troubleshooting steps in the manual. Release packages and source code are published on GitHub, where users can also report reproducible issues and verify the project license.
