Real-ESRGAN aims at developing Practical Algorithms for General Image/Video Restoration.
We extend the powerful ESRGAN to a practical restoration application (namely, Real-ESRGAN), which is trained with pure synthetic data.

- ✅ Add the realesr-general-x4v3 model - a tiny small model for general scenes. It also supports the -dn option to balance the noise (avoiding over-smooth results). -dn is short for denoising strength.
- ✅ Update the RealESRGAN AnimeVideo-v3 model. Please see anime video models and comparisons for more details.
- ✅ Add small models for anime videos. More details are in anime video models.
- ✅ Add the ncnn implementation Real-ESRGAN-ncnn-vulkan.
- ✅ Add RealESRGAN_x4plus_anime_6B.pth, which is optimized for anime images with much smaller model size. More details and comparisons with waifu2x are in anime_model.md
- ✅ Support finetuning on your own data or paired data (i.e., finetuning ESRGAN). See here
- ✅ Integrate GFPGAN to support face enhancement.
- ✅ Integrated to Huggingface Spaces with Gradio. See Gradio Web Demo. Thanks @AK391
- ✅ Support arbitrary scale with
--outscale(It actually further resizes outputs withLANCZOS4). Add RealESRGAN_x2plus.pth model. - ✅ The inference code supports: 1) tile options; 2) images with alpha channel; 3) gray images; 4) 16-bit images.
- ✅ The training codes have been released. A detailed guide can be found in Training.md.
- Python >= 3.7 (Recommend to use Anaconda or Miniconda)
- PyTorch >= 1.7

There are usually three ways to inference Real-ESRGAN.
- You can try in our website: ARC Demo (now only support RealESRGAN_x4plus_anime_6B)
- Colab Demo for Real-ESRGAN | Colab Demo for Real-ESRGAN (anime videos).
You can download Windows / Linux / MacOS executable files for Intel/AMD/Nvidia GPU.
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 (the Windows example, more information is in the README.md of each executable files):
./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n model_nameWe have provided five models:
- realesrgan-x4plus (default)
- realesrnet-x4plus
- realesrgan-x4plus-anime (optimized for anime images, small model size)
- realesr-animevideov3 (animation video)
You can use the -n argument for other models, for example, ./realesrgan-ncnn-vulkan.exe -i input.jpg -o output.png -n realesrnet-x4plus
- Please refer to Real-ESRGAN-ncnn-vulkan for more details.
- Note that it does not support all the functions (such as
outscale) as the python scriptinference_realesrgan.py.
Usage: realesrgan-ncnn-vulkan.exe -i infile -o outfile [options]...
-h show this help
-i input-path input image path (jpg/png/webp) or directory
-o output-path output image path (jpg/png/webp) or directory
-s scale upscale ratio (can be 2, 3, 4. default=4)
-t tile-size tile size (>=32/0=auto, default=0) can be 0,0,0 for multi-gpu
-m model-path folder path to the pre-trained models. default=models
-n model-name model name (default=realesr-animevideov3, can be realesr-animevideov3 | realesrgan-x4plus | realesrgan-x4plus-anime | realesrnet-x4plus)
-g gpu-id gpu device to use (default=auto) can be 0,1,2 for multi-gpu
-j load:proc:save thread count for load/proc/save (default=1:2:2) can be 1:2,2,2:2 for multi-gpu
-x enable tta mode"
-f format output image format (jpg/png/webp, default=ext/png)
-v verbose outputNote 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.
- You can use X4 model for arbitrary output size with the argument
outscale. The program will further perform cheap resize operation after the Real-ESRGAN output.
Usage: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile -o outfile [options]...
A common command: python inference_realesrgan.py -n RealESRGAN_x4plus -i infile --outscale 3.5 --face_enhance
-h show this help
-i --input Input image or folder. Default: inputs
-o --output Output folder. Default: results
-n --model_name Model name. Default: RealESRGAN_x4plus
-s, --outscale The final upsampling scale of the image. Default: 4
--suffix Suffix of the restored image. Default: out
-t, --tile Tile size, 0 for no tile during testing. Default: 0
--face_enhance Whether to use GFPGAN to enhance face. Default: False
--fp32 Use fp32 precision during inference. Default: fp16 (half precision).
--ext Image extension. Options: auto | jpg | png, auto means using the same extension as inputs. Default: autoDownload pre-trained models: RealESRGAN_x4plus.pth
