Image Super Resolution Tool
What Image Super Resolution Tool is
Image Super Resolution Tool is a free Windows desktop app for enlarging still images and folders with AI upscaling. It accepts JPG, JPEG, PNG, WEBP, BMP, TIF and TIFF files, and can scale images up to 4x. The installer includes ATD, HAT, Real-ESRGAN General Photo, and Real-ESRGAN Anime and Illustration models. The maker describes HAT as sharper but slower and more demanding on VRAM, General Photo as a balance of speed and quality, and Anime and Illustration as suited to artwork. The app detects an NVIDIA GPU model, its VRAM capacity and available VRAM, then selects suitable processing usage. It also automatically adjusts sharpening and denoising. During processing, a percentage bar, elapsed time and estimated remaining time show progress. The tool is intended for regular users and does not require coding. At first use, it downloads a local Python runtime, CUDA PyTorch and other dependencies to the current user's local app data folder. The maker recommends Windows 10 or Windows 11 and an NVIDIA RTX 4060 with 8GB or more. Initial setup needs a stable network connection and sufficient disk space. The software is provided under the MIT License.
