Real-ESRGAN
- Colab Demo for Real-ESRGAN .
- Portable Windows executable file. You can find more information here.
Real-ESRGAN aims at developing Practical Algorithms for General Image Restoration.
We extend the powerful ESRGAN to a practical restoration application (namely, Real-ESRGAN), which is trained with pure synthetic data.

We have provided a pretrained model (RealESRGAN_x4plus.pth) with upsampling X4.
Note that RealESRGAN may still fail in some cases as the real-world degradations are really too complex.
Moreover, it may not perform well on human faces, text, etc, which will be optimized later.
Real-ESRGAN will be a long-term supported project (in my current plan
Here is a TODO list in the near future:
- optimize for human faces
- optimize for texts
- optimize for animation images
- support more scales
- support controllable restoration strength
If you have any good ideas or demands, please open an issue/discussion to let me know.
If you have some images that Real-ESRGAN could not well restored, please also open an issue/discussion. I will record it (but I cannot guarantee to resolve it
Portable executable files
You can download Windows executable files from https://github.com/xinntao/Real-ESRGAN/releases/download/v0.1.1/RealESRGAN-ncnn-vulkan-20210725-windows.zip
This executable file is portable and includes all the binaries and models required. No CUDA or PyTorch environment is needed.
You can simply run the following command:
./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png
We have provided three models:
- realesrgan-x4plus (default)
- realesrnet-x4plus
- esrgan-x4
You can use the -n
argument for other models, for example, ./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n realesrnet-x4plus
Note that it may introduce block inconsistency (and also generate slightly different results from the PyTorch implementation), because this executable file first crops the input image into several tiles, and then processes them separately, finally stitches together.
This executable file is based on the wonderful Tencent/ncnn and realsr-ncnn-vulkan by nihui.
